Great job on that dipole. This why I can't believe that someone said that CB is dead. Well, listen to that, it sure busy on the band.

I made quite a few of these in my day . Use old Clothes line props or tent poles ! they work very well.
It’s fun to experiment with homemade antennas.
Sometimes they turn out to be the best antennas you’ve ever used.
Keep playing 🇨🇦
Thanks for posting the video. I'm in McMinn County, Tennessee.
I will be building an 11 meter antenna soon.
This coming weekend, there will be a radio swap and shop in Cleveland Tennessee.
I hope to make that one and pick up some parts and stuff.

It is a half wavelength dipole antenna. It can be mounted horizontally or vertically. It is a good antenna with plenty of radiation and gain.
Congrats! Now spent a few bucks and change that feed cable to LMR400 and your jaw will drop even more! Your losing so much effective power at the radials because your coax has high loss. I used RG8x at 50' for years and when I switched it to LMR400 I couldn't believe the difference. Both RX and TX where so much better. Cool idea for tuning it! I used solid core 10ga wire on mine but had to keep pulling it apart to tune it. But mine was mounted vertical. I might have missed it but how are you planning on long term mounting it? Horizonal or vertical?
Of course you had to pickup the loud mouth in the desert (Hard drive)...lol
I finally found your channel !!
I subbed 👍
I love my homemade single beam antenna. Been using it for 2 years. I'm using two 102" steel whips. Using 50 ft LMR 400 coax. 73's to ya.

@@jmanranger7271 hey whatever works. I'm walkin the dog and kickin the cat. That's all that matters.
I used a 102 inch antenna and a 102 inch length of wire and mounted it vertically with a center fed connections. It does great from 24.8Mhz to 30Mhz. There are benefits to mounting it horizontally also, if you have an antenna rotor. However, my antenna is on a fixed mount so a vertical is better.
I need someone to make me one or send me the parts
great dipole antenna. Sounds like it is working good on the recieve.
looks reallyreally
A little harsh but you’re right. 14:11
CQDX ! I haven't heard anyone say that in a long time 😆😆😆😆🤣🤣
say it all the time.
I say it regularly.
Single beam? it's a horizontal dipole. It's not a beam unless it has at least one director or a reflector.
I have that same CB 1978 model
looks like your mic gain is turn down your needle was not moving when you talked
Cheap driven element speaker wire is the best
I used that meter in 1971
Hahahaha, single beam, wtf? Thats a dipole! Omg
It can also become a vertical groundplane if two more 102 inch radials are set to the base of the antenna and spread out at around 45 degrees. I rather think a vertical dipole is likely better than a groundplane antenna.
Isn't this the same as a 1/2 wave centre fed dipole?
It's one with 102 and 107 inch3 Cb Radio Homemade Single Beam Antenna Female So239 Mount video and 102 and 107 inch Cb Homemade Single Beam Antenna Jb Weld UHF Female So239 Mount video on RUclips.
It's been weather proof with grollia glue spray on pvc pipe on camo so rain cant get in it.
Yup. That's exactly what it is, a 1/2 wave centre fed dipole. I think he gets the "beam" idea because when horizontal it "theoretically" radiates in 2 directions broadside but doesn't radiate off the ends.
Of course in the real world the radiating lobes will be all over the place depending on the quality of the ground underneath and the height that the antenna is mounted above the ground. (The dipole should be mounted as a minimum 1/4 wave above the ground, (around 9 feet for CB), but really it should be much higher than that. 18 feet above the ground is a good compromise height.
There is not much actual gain compared to even a standard 1/4 wave vertical. Certainly less than a quarter of an S point.
But still it is worth building because it is a good antenna :)
@@jasonphillips1777 If mounted vertically, it would radiate omnidirectionally. A vertical dipole requires no ground plane. I have one I made out of a 102 inch stainless steel antenna and a 102 inch length of wire and mounted it vertically.
@Indrid Cold yes but it isn't mounted vertically, so what's your point? I have made many half-wave end-fed antennae complete with appropriate impedance transformers. But we are not talking about that. He is taking about a horizontal antenna being a beam. Maybe you misunderstood . . . . . Everything??
Anywhere Knoxville????
I like how all these CB guys think a 1:1 SWR is all you need. If only it WAS that easy.
You say all CBers. I'm a CBer. Why don't you elaborate for me, you know, the other things for me. Please impart some of your wisdom. How about answering this question for me. What is the definition of antenna resonance, in this case, a half wave dipole?
@@arconeagain Antenna resonance is defined as the frequency at which the input impedance at the antenna terminals is purely resistive, but, your question lacks any actual context, for instance, what is the desired frequency, gain, bandwidth, impedance, and polarization? I could quote from the MILLIONS of pages of analysis, theorems, theses, and such done over YEARS of research by countless persons WAY smarter than you, but I'm sure you've read all of it already, so I would be flogging a dead horse with your superior intelligence in ALL matters antenna. So I turn the question back on you, explain how much you know, we're all ears.
Make me one and ill buy it
Its 12 gauge speaker wire inside PVC pipe it's been tune right I put 103 inches on speaker wire.when trim 102 the swr went to 1.0 back in 2022.

GOOD LORD MAN, WTF is a "single beam antenna"...sounds like something a CB'er would say, no doubt. You've built a DIPOLE antenna for the 11 Meter CB Band (26.965 MHz to 27.405 MHz) not a "Beam Antenna". Dipoles are directional from both "sides" (perpendicular to the radiating elements) but hardly a "Beam Antenna". Also the needle your SWR meter is not calibrated correctly, it should "rest" at the low-end of the scale, not a 1/4" below it, so you SWR readings are higher than you think.
