TV Antenna Signal Amplifiers Explained: Do They Improve Reception?
HTML-код
- Опубликовано: 15 авг 2024
- This is my video that explains the two main kind of TV antenna signal amplifiers: preamplifiers and in line amplifiers. Both boost the incoming signal either up at an antenna or on an incoming coaxial cable. In many cases they can improve your TV reception but not in all scenarios.

I have worked in telecommunication
Is it OK/necessary to use a distribution amplifier if you already have a pre-amp?
@@ChewyChicken589 no
@@AntennaManthank you, that's what I figured but I just wanted to double-check. I'm getting really good reception with just the Channel Master preamplifier anyway
I come here to check myself when making tweaks to my set up I started a few months ago when I cut the cord. When I first put up my OTA antenna I got 60 channels that surprisingly all come from the same direction. I was happy with what I got but I would lose a channel or two due to weak reception I guessed. Then I learned that all that extra run cable was hurting the set up coiled up in the attic plus the unnecessary 4 way splitter. I got a two way splitter instead and got precisely measured quad shielded RG-6 cables even remapped the cable run for the shortest run possible and trial and error correction antenna position and wham now I get 81 channels with 3/5 bar measurements on the weak stations instead of 1/5. I no longer lose channels and according to FCC website I am getting all the channels optimal to my area. I am satisfied and happy Tyler makes these videos.
Smart, concise explanation for those who don't understand the amp concept. Amps are made to overcome line loss in cable. You can't really boost or add gain to "no signal". Gotta have a signal to increase!
As Tyler continues to make good short videos,
he will amplify his number of subscribers.
Bahahah Good one . Grin
Both useful signal AND noise it seems. Hope that guy you installed for doesn't stiff you.
And he will amplify his pockets to so I think it's petty of him to say it takes a lot of time to make these videos so contribute to my channel.
He does a decent job of explaining and cheapens it with begging.
@@RG-gl6sm If it bothers you so, you should stop watching him. For those of us who are okay with his pitch, we will continue to view his videos......and learn things from him.
@@goofe.washington953 I did stop watching after this comment. These youtubers act like they want to educate people just because they are "good teachers " and don't want the public to get "taken" by companies making products but in fact they are after your money to. Just saying, and that's my opinion.
The preamp with power insert has been a breakthrough for me ! Thank you. And I used your recommendation of the onn preamp. Very effective.
And the fact that too much gain can make a channel disappear was a great help too.
This is the most informative place for Antenna set up that your ever going to fine. I’ve learned a lot here and made my set up work great from the get go. Thanks Tyler.

Tyler - you are 100% correct you have to buy the best antenna components to get tge best results i am bought a new antenna based off of your RUclips channel just need a preamplifier we have tree coverage but its thin out since the nabor bought the lot nextdoor and cleared out some of them helped out
I find all your videos very helpful Keep up the great work!
you did a great job answering all my questions and educating me on the subject. thank you
Tyler, great videos. I live just east of Akron, Ohio and have tried desperately to tune in a station out of Youngstown so I can watch Steeler games. Your tips have been a great help in tuning in that station. Very much appreciated.

KitzTech 500 and the ChannelMaster 8 port amplified distribution amplifier worked well for me.
3ft of rg6quad copper going from my Antop 400V to the KitzTech amp. Then 110ft going from the preamp to the channel master distribution amp and 10 to 75 foot runs from the distro amp to the sets.
Antenna boosters are good when using coax splitters to many TVs since those are usually -3.5dB or more per output port so adding a few dB close to the antenna helps compensate for that.
A distribution amplifier might be more useful in your scenario.
@@OlivierCaron Thanks for the "quick" reply (2 years).
@@davidjames1684 Olivier will send you a bill for the advice. Make sure to forward your contact info.
Thanks Antenna Man. I didn't understand what exactly the amplifier would do. Maybe I should have looked before I ordered a preamp, a distribution amp and an LTE filter. I wont get them until next week. I'll give them a try anyway. It can't hurt to have a try. I appreciate the clear and concise explanation that is common to all of your videos.
Truth and Quality.
Practical and Useful Information.
Many Humans think amplifiers " Pull " signal from the antenna , and " Pull " signal through coax.
This is not the truth.
----------------------------------------------------------------------------------------------
From a simple point of view the amplifier accepts the signal with the amplifier close to the antenna , amplifies the signal and pushes the amplified signal through the coax that goes in the direction of Tv's.
So the best place for the amplifier is , closer to the antenna.
Closer to the antenna means the signal is stronger to start with.
If the amplifier connected to the coax at a place that is far away from the antenna then the signal will be weaker at the location that is far away from the antenna and the amplifier will be starting with weaker signal.
Because the signal is stronger closer to the antenna , before going through a long length of coax.
---------------------------------------------------------------------------------------------
Here is Truth.
Antennas do not "Pull " signal from the air , the metal reception elements of the antenna Do Not work like a vacuum cleaner hose.
The signal acts on the metal reception elements , more metal reception elements means more signal received and transferred trough the coax to the Tv,s. Or if a amplifier is connected then through the amplifier and then coax to the Tv's.
Thank you for the straight forward information! Cuts through all the BS my friends try to tell me!
Thank you so much for your vast knowledge of antennas and signal! Super helpful!
"junky antennas I tell them not to buy but they buy anyway"
People, stop buying those junky antennas!!!!! 😂😂😂
I'm 75-80 miles due east of several Nashville transmitters up on the highland rim. That means my terrain sits higher than Nashville, which sits in a basin and must help my reception more than it should be expected from such a great distance. I've got an Antennacraft 8 bay antenna, model U8000 masted at the west gable end of my house about 22' from the ground to center mass of the antenna, and the strongest CM preamp. My coax runs the length of my house plus the rise, so it's about 95' but my power supply is plugged in before the length of the house is applied, because I originally ran two t.v.'s at opposite ends of the house. So the cabling runs about 60' with nothing to counter that signal loss.
About three weeks before repack 6, I was getting every high power UHF signal out of Nashville save CW 58. However, I'm pretty consistently receiving CW 35 miles to the east even with my antenna pointed west. I've got one local station 7 miles to the south that's PBS. It comes in full strength and rarely over loads.
Anyway, about three weeks before the repack date, MeTv programming left the ABC affiliate tower and went to an independent that broadcasts closer to my home by 1/4 the distance, and I used to get that channel but now have lost it. It must be at a lower power or lower position or terrain between us. This was programmimg we watched daily. After the repack, I've now lost Fox 90% of the time (used to receive it 90%), still don't have MeTv as a sub channel, CBS is weaker but usually comes in and Ion 28 is weaker nut still comes in. A Nashville tv forum states that Fox may be on weaker power temporarily but hasn't said; that CBS is definitely running weaker temporarily with a side mouny antenna; and that Ion is permanently gone to weaker power. So I'm waiting it out, but if I don't get back the performance that I had, how can I further upgrade? I know that I can replace my coax to run the power supply closer to my set running that power most of the length back up the line, or move my antenna to the other gable end to shorten down to about 45' and that either of those two actions should help some. I may can get a used tower take it down and erect it at my home. But what about my antenna? Is it guaranteed that I'd get more gain if I got an identical antenna and double ganged them together, or would that likely be a waste of money? I can get a high gain directional yagi, but then I may need a rotator and not a big fan of that hassle; and may possibly be no better or even worse off after spending hundreds trying to do better. The magnetic direction from my house to the transmitters are from 267 to 277. Distance is from 70-80 except for MeTv which is 54.
You are correct that simply throwing an amp in the works will NOT get antenna to "bring in" more stations or make weak ones stronger. The amp really can only help overcome "losses" during the signals journey from the antenna terminals to your TV set. I always install an amp like the first one that mounts right below the antenna on the mast. The exception would be if the customer is super close to the transmitters, like a big city, and has a properly sized outdoor antenna and a short run to one set. Regardless of city or rural installs, if customer is going to run a whole house system of like 4 or more taps to supply TV's in many rooms, THEN a strong distribution amp/splitter is needed. That's the metal box you showed with just 2 connectors and a power cord comes in handy. Of course the output would go to a multi tap splitter then. Oh ya, it fun.
Hey I have a channelmaster extremetenna 80 that I bought for my mother about 3 years ago. She lives in 38012.I installed it myself and used her existing directv dish mount. I also installed a pct ma2 amplifier. The problem is she gets better reception on cloudy days than sunny days, she can even do a rescan on cloudy days and have new channels coming in from further away. On sunny days those channels disappear. What is the technical reason for this?
@@memphistiger4647 Wow, interesting. As long as the station antennas are within reception distance, all I can think of is maybe moisture has gotten into coax or signal amplifier, or connector exposed to the sun? Meaning, the warm sunshine may cause condensation to form in the part killing signal, but when colder, moisture may vaporize a bit and not attenuate the signal as much. Just a guess.
@@curtchase3730 It's really a weird thing. I'm gonna have to play with and replace things to see what I come up with. Here in TN when the snow came all last week and cloudy overcast she got great signal on all channels. Once she got the first peek of a sunshiny day some channels disappeared. I haven't seen any Google posts yet like this.
Some realities of antenna amplifiers from a radio tech/spectrum policy wonk:
• A key issue if the "noise figure"/NF -en.wikipedia.org/wiki/Noise_figure- of the amplifier. NF is a measure of the sensitivity of the amplifier and is different than gain. Unless the NF of the amplifier is comparable to or lower than the NF of the TV set it won't help in most cases. Unfortunately NF data is rarely available and it is difficult to measure outside of a lab.
• "Third-order intercept point"/IP3 -en.wikipedia.org/wiki/Third-order_intercept_point- is important if you are in an area with strong signals and you want to receive a distant weak signal. IP3 is a measure of how much the amplifier unintentionally converts strong signals into noise at otehr frequencies, such as the one the weak signal are one. Fortunately this conversion is only possible for certain mathematical relationships between the strong signals and the weak signal frequency (NOT channel number)
• If a indoor antenna with a short cable to TV has an amplifier, it may actually make things worse than an nonamplified antenna if the NF and IP3 values aren't adequate.
• Using an amplifier to cancel loses in cables is most useful with outdoor antennas with long lengths of cable. Then again, best to check IP3 and NF though.
I live 1 mile from the TV broadcast towers... lots of overload here, but I use a high-gain preamp because I have custom filters that attenuate all 6 MHz of each of the 3 blowtorch DTVs here before my preamp in the attic.
Google User, FM broadcast is also a problem, but all the others you’ve mentioned at not a problem at my particular location. So the easy solution is to add an FM bandstop trap. The ones built-in to the preamps are not adequate to attenuate strong overloaders below 92 MHz, but a full bandstop is. Don’t forget LTE cell phone tower interference. That’s a big problem too if not addressed. Channel Master makes traps for those. But only use what you need, since attenuating everything is not necessary. You just gotta find the reason for your particular problem.
My experience with preamps is to use coaxial cable with a solid copper core rather than copper clad steel coax. Copper Clad coax works fine with indoor inline amps but I wouldn't use it again with a preamp, I'd make sure to go with solid copper.
I have a little old TV indoor antenna that came with the TV purchased 25 years ago. I also have an older GE multimedia drop amplifier I purchased about 15 years ago. Using it makes quite a bit of difference between with or without it my Digital television
Quite likely the extra cable run is providing that perceived signal boost. There is absolutely 0 reason to use an amplifier on an indoor antenna with a short cable run. It amazes me that people can watch and listen to a scientific explanation and then infer the science is wrong because they don't understand how their own equipment works. Almost always when I see someone describe their equipment with a heavy dose of nostalgia involved (I bought this 500 years ago!!! Kids these days!!!!!) they have 0 idea how that device works, nor have they tried any sort of comparison or double blind test. I see this in a lot of communities, with audiophiles generally being the worst.
I'm 99% certain that youd get better performance out of a random wire run from the antenna socket of your TV than that crappy old setup. Would not surprise me 1 bit if that pack in antenna has long since corroded its connections or has a blown out balun and is essentially doing nothing and all the work comes from exposed copper and steel along the signal path getting just enough gain from the amp to work.
Great info! I had no idea this is what an amplifier did!
Great explanation Tyler; keep up the great work. Bob
Thanks for the video .. great information ... I actually learned something
Yes good explanation and every time I tried Amplified it was horrible worse anyway still beats the cable. Bill I actually have a three-year-old antenna now it is weird it works better outside sometimes it's an indoor outdoor antenna my cousin actually gave it to me I get well I have to move it around a different spot but I can get 32 watchable channels that's pretty good for me anyway thank you
Thanks Antenna Man!
This young man has put out a lot of great information. However, one subject that I have yet to hear discussed is RG6 copper clad steel vs solid copper core. It's my understanding, and I'm relatively new to this subject, that solid copper core RG6 is the only RG6 that will work with a pre-amp because the copper clad steel core RG6 isn't capable of carrying enough voltage back upstream to power the pre-amp. Tyler, can you chime in on this topic, or any other readers out there? Thanks and keep up the great work.
thanks for this. removing the amp from my antenna improved my reception quite a bit
its all about signal to noise ...so a pre amp is always the best option for weak stations.
I have both a Clearstream 2V and Clearstream 4V combined through an RCA preamp (the 2V connected to the VHF input of the preamp). Both 2V & 4V have VHF dipoles and the whole set up is outdoors 30 feet up. I still need a Channel Master inline amp to get our local channel 5.1-5.3 which includes our ABC affiliate and Cozi we watch all the time. It took me some time to figure out the configuration that can get me these channels but I finally hit on it, the signal is just so weak. If I remove even one of my components though I lose the 5s. It really irritates me that it's so difficult to get ABC, a major national network, around here with an antenna. I now get every single OTA channel available in my area but boy was it a pain to get them finally.
Everything I spent years telling customers at Radio Shack. I wish I could find a adjustable gain preamp like we used to sell however. Some stations it helped turned up, some all it did was amplify the noise. Btw you mentioned quad shielded cable, but not why it's good. Same with RG-6. Shielding keeps interference from electrical devices and other transmitting towers from affecting the signal, and RG-6 is a much lower loss cable than, wow it's been a while, RG-59?
I have the clearstream 2max antenna mounted in my attic as I did not want it outside.. I have it pointed at the abc tower that is only 20 miles away.. I also added an lte filter and replaced coax as I was getting pixalation .. While it no longer pixalates I still see and get weak signal comments on my tv.. Does this mean I may need an amp to boost signal to push through shingles? Was looking to get a channelmaster CM 3412 2-Port as I eventually want to hook up 2 tv's.. Right now I am just trying to secure the one so I can cut the cord.. lol... Thanks for you helpful videos..
At what distance (feet) of coax should I be using a preamp?
Post-repack I need to rebuild my yagi, it's now designed to pick up 4G & 5G, not broadcast TV. I need longer elements for the 600mhz frequency...shorter elements calibrated to 700 or 800Mhz aren't doing the job anymore.
Adding more yagi directors will narrow the "gain bubble", but this makes sense in regions like Philly or NYC where all the channels are broadcast in one small location (Roxborough or One World Trade, respectively). That's how you pull in more channels. The preamp simply gives the signal a boost down the lossy coax.
I would purchase one of those Channel Master LTE filters. About $15 and is outdoor rated. on the reverse end of the spectrum, FM traps are also a good thing to have if you have low channel hi-vhf and low-vhf channels in your market.
Do they make a signal joiner for three or more antennas? Or would a person just have to gang them with a couple of two way joiners? I have a pretty tall tower and need to get three antennas in different directions I really don’t like to mess with a rotor.
I made a video on this topic. Combining two antennas directly can result in multipath interference that kills weaker stations. Your best bet is to purchase a rotor.

Your videos are the best I’ve seen
Good video. my indoor antenna that I travel with just broke and I'm thinking about buying a non-amplified indoor antenna and buying an in-line amp since I can connect more devices without dealing with signal loss.
Very very very helpful and thank you for your knowledge
Any in-line amplifier I have ever tried has always made my reception worse. Granted, they were all el-cheapos. :-) The problem with mast-mounted pre-amps is they tend to get zapped by the first lightning storm that comes within 10 miles of your location.
@THE ORIGINAL PROFESSOR CHAOS I don't think making your post all-caps helps you
I have people calling me up asking questions about how to set up an antenna system. It's not that I'm against giving help but one thing I've learned that there is no one size fits all. They get upset with me because no matter how good they are at describing the situation, it really all depends. There are so many factors involved that there simply is no way I can give recommendations unless I can run diagnostic tests at their location. This is why I'm starting to charge $80.00 to give estimates so I don't waist my valuable time with those that are simply looking for me to teach them how to do it themselves on my dime!
80 bucks? Too much . 40
I'm with you John. I have a lot of people that ask me pretty much how to setup a situation based on their specific scenario. At first I asked for voluntary contributions to my channel but very few contributed. Now if someone sends me an extensive list of questions I request a $10 channel contribution or I won't waste my time. I am not trying to be rude, greedy, whatever you call it. I have very little free time with how much my business has blown up and it's not fair for me to spend hours helping people out. In a way I am providing them a service.
@@curtismuma1931 I'm sorry but I simply can't afford to be giving my time away for free nor cheap. Electricians and plumbers charge on average $80.00 bucks for house calls. I also apply the charge to the final price of the completed set up just like they do. Besides, it only takes a few cable bill payments to pay for my service and then it's free for ever afterwards.
@@AntennaMan At the end of the day our service is valuable! If set up correctly the customers will have trouble free service for 10, 20 or more years.
@@curtismuma1931 If I may be frank, would you charge $40.00 to basically teach someone how to set up a system that would last them 20 years or more?
Those drop amps cable companies use work great.
PCT makes some awesome drop amps.
They even make models that work with MoCA now.
So a preamp or amplifier isn’t useful in any scenario where you have a short coax cable run?
hi, I am in Baltimore and I live 4.6 miles from Wiz tower channel 13. it broadcasts in vhf. I use the amazon recast and I get very pixelated picture. I have a 4 max clearstream antenna. have you heard or do you have any info on the amazon recast issue? when I use the built in tv tuner everything is fine. I think the signal is too strong for the recast. is there something that can reduce the signal?
Good info. I am only 8 miles from most of the transmitters so an amplifier doesn't make much sense. But this is helpful if you live further from the towers.
Depends. If you have a really long coax cable or lots of splits then a preamp will still help. I would go with a variable gain preamp, like the kitztech 0-35db kt500 model.
@@lakorai2 I didn't realize you could get a preamp with variable gain. I only have two TVs and live in a condo, so there is not a long coax run. But if a station is tinkering with its tower and goes to a lowered signal, this might make a difference.
@@hilaryweiner893 there are only a few unfortunately on the market.
KitzTech makes 3 variable gain amps depending on your situation and canle run.
The kt-100vg goes from 0 to 20db of gain and would work well for long cable runs when close to a tower. It does not have an fm trap or lte filter.
The kt-501 is a dual purpose fm and tv preamp with a 0-18.5 db gain. Supposedly best for pulling in fm stations.
The KT-500 is the one I bough which has a 0-36db gain and an fm trap. This would be best with a tv antenna no matter how far the towers are.
ChannelMaster has a CM-7777hd dual mode preamp, which Tyler here has reviewed multiple times. Has a 18 or 33db selectable gain, but not fully variable.
Lastly is the Antop SBS series of antennas have a preamp with an inside variable preamp. This is pretty nice since you can adjust it without having to go to the antenna mast. It however has a gain from 8db to 22db and it's noise figure is over 1db; KitzTexh is all less than 1db.
The CableTronix CT-BDA24 ia a 6 to 24db preamp, but has a high 4db noise spec and I would avoid it.
The ChannelMaster is the only one with a built in LTE filter. However I would recommend the KitzTech models with an external Channelmaster LTE filter do to their much lower noise specs. You shouldn't "need" an fm trap unless you have lo-vhf stations, which are rather uncommon now. Most stationa after the fcc repack went to UHF and a few straglers are still pn hi-vhf (channels 7 to 13)
@@lakorai2 Thank you!
I replaced the cheap, "I don't recommend buying it" antenna with a Clearstream 4MAX and went from 40+ stations to 6. I guess I'll be returning it and buy another cheap one. My cheap one lasted about 3 1/2 years but was damaged in a windstorm.
A.M. Since Coaxial cable looses signal, what about using a Solar MC4 cable instead. They are meant for very weak current transmission. I have tried coaxial cable on my solar system, (cheaper) and it wouldn't conduct enough current. Please experiment with a Solar cable with MC4 connectors to see if you can reduce signal loss.. :)
Tyler, Did you see that 6 ABC Philadelphia asking people with antennas asking if they have issues receiving their station. The survey results are going to be used to try to get FCC permission to boost their signal.
No I did not. Thanks for mentioning this. Where did you hear this? Their signal is horrible. Even I have trouble getting them in some areas.

Thanks for the info John. I'll be sure to share the information in a future post. When the weather cools off let me know if you need help with your setup. I believe you said in the past you were in the Lehigh Valley.
@@AntennaMan Thanks! Yes, I am in Allentown and good for now. The cheap antenna is now on a 12' pole on the roof, the pole and cable are grounded. I have two TVs and a free standing DVR working fine. When the cheap antenna dies I will put up a big yagi with long VHF elements. I have been having fun tinkering with antenna stuff and VoIP. I am a techy guy who does IT work for PPL.
I bought the Channel Master 7777V3 and it worked extremely well for 4 days and died. Exchanged it for a 2nd one and it worked great and died too. No storms, no lightning, no reason I can find for the failures.
They shifted their manufacturing plant to Bulgaria so that may have something to do with it
my best recipe so far; RCA ANT122Z $18. on amazon. PLUS HDTV Antenna indoor rabbit ear Retractible Dipoles 33694 by GE $14.50 on amazon. the main rabbit ears is the RCA where one ear is a straight up and the second ear is angled to the best reception. i use an inline amp boost on this (just a random one left over from a black square ant. that didn't work). i add the RCA for UHF mostly and it has an inline amp thats not plugged in. adjust these elements or move the wires to them -cause even the wire placement matters. here on the west coast LA area i find if you can receive channel 7 and channel 9 you will get all VHF channels . UHF is easier to get.- you may not need the GE ant. at all.
Some of those Mohu flat antennas come with little junk amplifier devices. Have you ever measured how well those work? I live in a metro are and use antennas like those as a backup for cable outages and blackouts by the cable company.
Thanks man, great vids very helpful. 👍
I remember once going to a service call, I got there early, standard 40' house, I checked the cable signal outside + 6 dbmv; the owner drives up he has 1 new projection TV that's it, he was maybe 25 feet in, I expected +2 to +4 ( less if he has a hidden splitter ), My SSM was pegged ! took 3 -20DB pads ( I just needed to know : ) ), I asked him where his amps are , he had 3 daisy chained so he burnt out his tuner.
I disconnected them went back to his TV +3 dbmv, but...he burned out his tuner, I told him call the place he bought it, and don't tell them he had 3 amps connected.
Back then those TV's were pricey for subpar pictures.
Too much of a good thing is just as bad as not enough, sometimes it can be worse.
I got the new Channel Master Pro so far it works great just to let you know I purchase it 2 weeks ago. And there are already sold out.
Good information
Thank you for posting this helpful video!
Thanks for watching it!
@@AntennaMan Your channel is excellent, in my 61 years I've learned more about antennas from you in 20 minutes than I have ever known:) Thanks very much for all the work you put into these videos.
You should talk about noise specs too. Not all preamps are created equal.
What if you already have an amp, but it's some cheap 20db one, will a better quality amp with say 25db or even higher help? I have a channel that sits between 30-50 signal and it just barely comes in sometimes or not at all, I just have a buffering icon forever.
I am in Phoenix. All towers are NW of my location. NBC is light green for my address on that website you suggested. Some days I get NBC and some days I don't at all. It is driving me crazy.
Always helpful. Thanks.
Good video and thanks but I think more should be said about how boosters will boost all channels at the same time. Most booster problems start when you receive a strong channel and a weak channel. If you boost the weak one it will normally degrade or wipe out the strong one by saturating it. Always buy an adjustable or variable booster so you can find the sweet spot. At least until they decide to produce a better quality booster that will attenuate the signals. Personally I have not seen one for home antenna systems and that's because it will be expensive.
I am always amazed at how nobody seems to use TWIN LEAD wire instead of coax. In many instances, you can skip the preamp entirely if you just use twin lead, since it's not so lossy in the first place!
Twin lead is also less shielded from interence from other signals and electrical interfence for things in modern homes.
Twin lead used to be common 50 years ago.
This is one thing I learned about preamps is it makes a simple connection complicated.
Thanks I like my yagi
Hi Tyler, I'm a new subscriber.. I like the contents of your channel and your short videos straight to the point... I cut the cable TV and installed an outdoor antenna, but since I still have high speed internet, I was wondering what are your recommendations to run the air antenna signals and the COX high speed internet combined in one cable, if possible, and what combiner you'd recommend to accomplish that task... I only have one RG6 cable running to my living room and I'm trying to avoid running another cable and drill another hole on the wall...Thanks a lot in advance! Eddie.
You CANNOT run broadband and an antenna on the same line. It will affect your internet and possible your neighbors. In an extreme case the ISP may disconnect you. You'll have to run another wire to connect the modem...
I bought a RCA ANT3036 antenna and installed it on top of my two story house with a RG6 coaxial cable. I have a Visio V585-H11 smart TV. I bought a TiVo Bolt OTA 1TB. My problem is I can get 32 channels through the TV channel scan but through the TiVo channel scan only 16 visible and more that the scan found but the screen is black when I go to that channel so I called Weaknees because they were the company that refurbished the TiVo. They said there is nothing is wrong with the TiVo . They said I needed a amplifier because the TiVo required a stronger signal than the TV because it shows the picture frame by frame. What would you recommend I do? Thanks Greg
Does it matter where you place the power source as long as the preamp is within a few feet of the antenna?
Some people plug it in behind their TV's even tho the preamp unit is near the antenna.
I have a Terk TV42 that clips to my satellite dish which I want to discontinue. When I disconnect the satellite receiver the TV42 doesn't pick up any signal at all on scanning. Is there a way to make it work without the receiver?
Antennas Direct Juice should be on that list.
I must be an anomaly, 84085 zip, 25’ of coax on a small outdoor Wally World special. 11 channels before.Ran an onn preamp and generic inline,, 41 after 🤷🏽♂️ being a CB enthusiast, a pre amp does amplify the RF gain, meaning receiving frequency is amplified, and an inline amp, boosts what it’s given but idk
Thanks.... your recommendations really helped.
I brought the antenna that you showed in your video and I was wondering if I need a antenna amplifier for it
It depends. If you have a long coax cable over 30 feet an amplifier might improve your reception. Otherwise one might not be needed if you don't have any issues with your local channels. You can find a list of recommended amplifiers below. www.amazon.com/shop/antennaman/list/XLT94P404QUY
Good points! Thank you for producing this. I was considering installing an inline amplifier but based on what you convey, I don't think it will help my TV reception situation.
Q: Is it possible to damage the "front end" of a TV receiver if a signal is over-amplified at the RF input? If so, how likely is that to happen if you daisy chain two inline amplifiers together? (Asking for a friend.)
Yes you can damage a tuner that way. Limit an antenna to one preamp or powered cable splitter
Super helpful, thanks!
I don't have a long run from my antenna to TV and when I don't use my electroline 8 port the digital signal is weak and scanning stations without it on gives me only half of the available ones. I'm not technically savy on this subject, and even though your explanation was very detailed, I'm not grasping why it gets more stations with it on if it doesn't magically pull stations in as you put it? I'm really asking and not trying to be a smartass just an FYI
I have a new Sony Bravia, 65", cheapo from Costco. I think has a QAM tuner. Gets No Channels, cable or non amped antenna, so.... think its the Antenna or the TV? Also, My old Visio 43", ten yrs old, gets the cable and antenna channels. Again, Bravia gets 'no' channels. Yes, tried all the menu combos but nothing. Any thoughts appreciated.
I installed the Radio Shack in Line Amplifier, but for some reason some channels did not work saying no signal while other channels worked well. Absolutely no help from Radio Shack as to what is the problem
How would you make a range extender antenna on a drone remote controller powered? You can buy them amplified but there like $500 . I paid 150 for non amplified antenna , is it possible to convert it myself??? Thanks
My experience with preamps wasn’t very good because although I was using RG6 Quad Shield Coax, it was CCS meaning a copper clad steel center conductor. TV frequencies tend to travel on the skin of the wire and this cable will do fine. However, preamps require electricity and electricity is at a much lower frequency and travels through the core of the cable. In this case that section of coax from the power supply to the preamp should have a solid copper core as copper does a better job than steel at conducting voltage. The CCS cable is just fine for everything else including being used with an indoor amplifier. I used CCS coax and my Channel Master CM-7778 preamp burnt out in 6 Months. Even some connectors were burnt out.
My coax is less than 2ft long, yet with an amplifier it got more channels and cleaned up channels that were pixelated. Why?
Truth and Quality.
Practical and Useful Information.
Because amplifiers do.
And Yes I know that there are many Humans at the internet web sites that say no the amplifier will not improve reception.
However Defacto by the very nature of the act , the amplifier Yes does improve reception.
Is a situation of misinformation becoming the truth.
This is a common situation on the internet , misinformation being accepted as truth.
And the Humans repeating the misinformation over and over again with out thinking about what they are saying.
And Yes amplifiers can be overloaded by strong signals and this will cause bad reception.
Do you still need a ground block. Some Amplifiers state the coax should run from the device directly to the indoor power supply. How do you ground that?

Can anyone recommend a diy amplifier circuit?
Good info as always.
Another reason you may need an amplifier is if you split the signal. A 2 way split contributes at least 3 dB of loss in each leg.
I see you cover this in other videos.
I keep having internet and cable service problems? Do have any suggestions.
My antenna came with an amplifier. Luckily it was a removable inline amp because it did in fact make my signal worse. The antenna works great without it.
Didnt know that....thanks
Yeah it does help dude. I installed one for myself and it helped me get 3 new channels. 😏
Did you even watch the video? If you got more channels from using and amplifier it's likely because of signal loss in the cable.
Hello Antenna Man. Have you ever heard of this from Home Depot and do you know if it really works as a booster and a signal finder? Philips Outdoor HDTV Antenna Amplifier with Built-In Signal Strength Meter 4K digital signal booster. Thanks!
Hello what kind of amp should I use for my indoor antenna? And or what cable. Please let me know ASAP

CAN YOU USE A TELEVES AND A ARRIS DROP AMP TOGETHER thank you
Do I need HD coax for a 15 - 25 ft run?
No such thing as HD coax. You want RG6 quad shield coax. You can find a list of recommended cables below. www.amazon.com/shop/antennaman/list/4RBGOO8SD5CC?ref_=aip_sf_list_spv_ofs_mixed_d
I have a question about the use of distribution amplifiers and RG6. My set up is both good and sketchy at the same time. I use a Clearstream 4 max atop a 50' tower ( with an OLD school rotator from the 70s) in a rural area close to town. (Necessary because I'm in a low area with heavy trees , and the height gets it just at or above tree tops. ) Cable length and condition is my problem. All told, its probably 130' of cable into the attic where it hits a 4 way distribution amp. 3 of the taps are in use and I'm about to hook up the 4th. Is the loss present for each tap there regardless of whether all taps are used or say just 1 ? In other words, adding the 4th tap isn't going to affect the other 3 , right? A second question is about RG6 cable performance based on age. Its run underground in conduit to the house , but is now over 20 years old. When I cut new connectors on , the shielding foil and braid is very weathered and oxidized , but intact. The center copper seems good and isn't green . But I always wonder how much performance I'm losing because of the old cable. The system is very usable as is and pulls in all the local stations i am supposed to get , with weather sometimes degrading the weaker stations. Running new cable would be both very expensive and laborious. Just seeking opinions...
In general the cable can have a huge impact on your reception. See video below: ruclips.net/video/2xiDvxz35Ec/видео.html

Is there a Canadian version of antenna web?
Do you have a recommendation for the type of coaxial cable to use for burring a coaxial line? (I just dug a trench to move my propane tank to the back of my lot by my garage and thought I should drop an antenna line in there too. It is about 18" deep) I am putting my Yagi Antenna up on my Garage Roof 20+ feet high and to my house is about 125 foot run to my connectors. Thoughts?
RG11 is what you'll want. amzn.to/2MCpQtl

I have the GE Pro outdoor/attic mount antenna. About 100ft of RG6 coax cable. I am looking to split the signal to my bedroom. I know I need a distribution amplifier because I tried a standard splitter and that was a nightmare. However, if I was to add a preamp to the antenna on the roof, would I need a distribution amp to split my signal or should it be okay? Great video!
I don’t know if you know anything about broadband. I live in an area where I just very poor signal. My LTE signal other than just one side of my mimo antenna
Thanks
