I think that I would personally recommend a diversity receiver using a circular polarized antenna on one channel and a (helical or patch antenna) on the 2nd channel over an antenna tracker with a single antenna, the tracker costs more and requires that a device on your R/C sends your coordinates back to the tracker. It is also important to note that some vendors in Asia sell Right Hand Circular Polarized (RCHP) antennas as well as Left Hand Circular Polarized (LHCP) antennas and they do not work well together. Most vendors appear to sell RHCP units but a few such as Foxtechfpv.com sell LHCP units so be careful not to mix the two.
Another good vid thanks. What I have not seen anything on, is the number of leafs on a circular polarized antenna. Often it said to have 3 on tx and 4 on rx, and some of these antennas have 5. I imagine that it's not really a big deal, but I'm just curious because there doesn't seem to be much between the different brands available (other than quality) and prices. But some people recommend certain circular polarised antennas as the best (perhaps it's just personal preference).
What is the max. range with both circular antennas @ 5.8 Ghz 600 mW in your opinion? I mean I dont want to build an antenna tracker for helical and at the same time I want to fly about 5 km. Is it doable? What is your experience in that matter? Will cloverleaf antenna suffice for 3-5 km ?
Max range will happen with a 600mw or larger Vtx on the model with a circular polarised antenna and a more directional antenna on the ground (patch, helical, crosshairs). There are about to be some very cool RSSI based antenna trackers on the market that will mean that by using a few of those type of antennas in an array you can get great distance and coverage too. Watch this space!
Hi Colin, glad you found it useful. There are a few more videos in this series that you may like and find useful too. See ruclips.net/p/PLYsWjANuAm4rQfddw-7YZDzckoJ_KyOpm for the playlist. Happy flying!
Hi Professor, are Helical compatible with RCHP and LHCP clover leaf antennas, or would they have to match the circular direction, please? I can't find any info on this one; would you happen to know, please? Cheers and Safe Flying!
Which mean I need a circular antenna 3dbi and a patch antenna 14dbi for my fpv goggle that with dual antenna. This a good idea for indoor(circular antenna) and outdoor(patch antenna)
Ah right. My quadcopter s antennas are near vertical and my tx is horizontal at the min. so I should have my quadcopters antennas horizontal and my tx horizontal. Hope I got this right thank you for taking time to help me CHEERS!!
I thought your video was very clear and well described. A major issue I am struggling with is how to tell right hand circular polarized antennas from left hand. Could you please either add to this video or do another which describes how to tell for clover leaf, helical, and patch antennas? For example, are left-handed clover leaf antennas those with leaves that when turned in a clockwise direction will tend to "drill" into a surface at the end of the antenna? Or am I mixed up? Also the methods for RHCP and LHCP with helical and patch antenna polarization are desperately needed by someone who knows. Thanks. Jim
James C Eastep You can see the difference if you Google and look for the antenna that don't' have the covers on. Most will be right hand unless otherwise stated. You need to make sure that the Tx and Rx share the same type to work. Happy flying!
Hey quick question my reciever has a dipole and my transmitter has a cloverleaf. Will that work? and I wil really reccomend your channel to fellow pilots!
it was a very informative video and I did learn plenty. I'm a newbie in drone flying and became interested in aftermarket antenna's when researching goggles for flying drones. I LIVE IN THE COUNTRY AND WILL BE FLYING HIGH AND FAR , MOSTLY. It didn't occur to me that both drone and goggles could benefit from aftermarket antenna's. 1st, let me describe what equip. I am interested in purchasing : Drone : Xiaomi FIMI A3 5.8G 1KM FPV With 2-axis Gimbal 1080P Camera GPS RC Drone Quadcopter RTF - 5.8G FPV Goggles : New V2.0 Version FXT VIPER 5.8GHz Diversity HD FPV Goggles 2nd, some people have mentioned or obviously replaced original antenna's w/ 2 different aftermarket antenna's on the goggles (patch on 1 side & circular polar on the other). Question : What is your opinion on this technique ? (benefits, pro's / con's) ? 3rd, all that said, what is your antenna recommendations for setting up my 1st drone system, (goggles & drone) as I have described above ? Thanks you very much for your generous consideration, sincerely ............................
Take a look at the other videos in the Introduction to FPV playlist for a lot of the basics to be covered. I use Fat Shark goggles with a good diversity receiver with pagoda antennas on the model and goggles and a patch antenna on other conection on the goggles too. Best of luck!
Thanks, What is the best orientation for the Circular polarized antenna on the receiver and transmitter, do they have to be pointing upward or downward for best reception
Great vid. Question: my Splashdrone has a simple dipole antenna in the arm, sitting horizontal. Not the best but it's meant to be waterproof. Video reception to the Diversity stinks, two cheap dipoles on it. Would a combo helical and cloverleaf improve that, I assume the dipole wire means it's not circular polarized.
+NorthOlbo You need to look at using a circ.pol antenna on the Vtx (I use SpiroNet from FatShark mainly) and those antenna on the Rx would work well. Best of luck..
Hey @Painless360, your videos are amazingly informative. I understood a great deal from your video about quadkopters. I have a whip on my video receiver and a circular on my video transmitter, I get lot of signal issues, I don't do much of long distance, but I need to do it between buildings and trees etc? currently i have whip on vRx and circular on vTx.please tell me which combination I should use to make the best out of it.should I use both circular to get a good reception?
Awesome video. Very informative. I have a couple of Hubsan H501A and SS drones with their advanced H906A controller. These drones have 2.4Ghz for the control and 5.8Ghz for the FPV. I would like to have your opinion as to what setup would give the best transmission/reception for 2.4Ghz control and 5.8Ghz FPV for doing long waypoint flights for video recording. I seen many videos on the so called best antennas and still have no idea what TYPE(S) of antennas would work best for this. I have modified the drones so I can put whatever external 2.4 and 5.8 antennas on them that I need too. So, I should be able to use paired antennas if that's the way to go. Great videos dude thanks for posting on RUclips...well done.
wow great video! I have a SJ-V01 goggle that comes with two rp-sma connectors. I fly in a park full of trees and primarily keep the quad 90% of the time in front of me. Would getting a circular antenna and VAS crosshair antenna work together on my goggle to maximize range as well as all around flight or is that overkill?
+SlNlST3R If you are in a park then a good set of circ. pol. antennas should be fine. As you've got diversity I'd add a second antenna, something like a patch that will give you a good degree of 'view' and increase the range in front of you a little too.. Best of luck!
Would you be able to suggest to me a setup that would get maxium penetration and decent range? I was thinking diversity with a circular polarized antenna and not sure on the second.
+The RCAddict Depends on how you will fly. Extra range is achieved by reducing the coverage you get. I would use one of the setups in the video - circ.pol. and helical or two helicals.Best of luck and keep in mind any laws concerning maximum distance when flying RC..
Understood. Then if all of the trees are in front then I'd use a circ.pol and a low turn helical pointed directly at the trees. Remember that 5.8GHz has very low penetrating power so you are relying on reflections from hard objects to bounce the signal back to you... Best of luck!
Because the pros/cons of the CP Antenna and the Planar/Helical antenna, wouldn't the best course of action be to use a diversity system with a Circular Polarised antenna and a Planar/Helical with a tracker? This seems logical, but is it practical and actually feasible?
I a complete newbie to this so please excuse me if this is a dumb question but I own the eflite umx timber and I recently purchased a ready to go fpv system. I had a mini dipole antenna. I'm looking at buying some goggles that are diversity with a patch and a clover antenna. Will this work well? Do I need to match antenna types?
Please see my reviews of the little indoor quadcopters. If your model has a little dipole antenna, then you're better putting linear antennas on to your goggles. I like to use a linear antenna dipole as well as a linear patch if I'm flying one of those. Hope that helps
Hi, love your videos. i have a older system( fat shark dominator with a dual diversity mod set up) so i noticed on my googles the patch antenna is lhcp and the other attenna mad mushroom is a rhcp. for the plane in this setup does it matter if i use a left or right circular antenna?
Great Video - Thank You! I have a question though...I have recently purchased a diversity receiver and a patch antenna (as shown in your video). The patch antenna has the sma connector at the rear (to connect to goggles, I assume) but if connected to the receiver, it will point upwards! Looking at your video, I have to assume it won't be as effective even though I have noticed some people have indeed connected their patch in this orientation. May I ask what your thoughts are on this? Regards Stuart
The way that I've got round this is by using one of the following two options - 1) buy an SMA extension cable, get a thick one and you can bend it to shape 2) Buy two SMA right angle connectors, plug the first into the goggles and the second into that one so you can mount the antenna facing slightly up (dl.dropboxusercontent.com/u/67301981/Goggles.jpg - sorry for the roughness of the diagram but you get the idea!) Hope this helps. Happy flying!
Then when people use a circular antenna and a patch together they can fly on a field on a decent range and then when they facing the quad they can go even further? Is this like the typical combo?
Hi again, I was wondering if you could explain antennas a little for me. Normal transmitter antennas. I'm confused about if I need 2.4ghz or 5.8 and what dbi and gain means and if there's any laws when it comes to it. Thank you.
+Mystical Daptfyie the vast majority of modern radios are 2.4ghz, they use linear or dipole style of antennas for good all round reception. Same principles as the ones we look at in this video.. Happy flying
please ;i wannt to khnow what a frequence can i take in the 4g for the telephonie mobile not for other applicatiobn just telephonie mobile i need it fo my brief thank you
+Chahinez Drif I'd look at the websites for your local authority you'll find it. A google search will usually let you know too - www.4g.co.uk/4g-frequencies-uk-need-know/
Hi, question, can I use a vertical polarised Panel antenna as a transmitter instead of a receiver. I want to use it for my Phantom 3 standard RC transmitter which gives me hardly any range.
hello painless 360 good video it is helping thanks ……. my question is could you use a right hand clover with a patch and or with a helical ,say a five turn r/hand helical for instance and if you had, say the eachine 2000 goggles i think thats what there called …. those new ones you know.could you use patch and helical with clover all at the same time
It's one of those things that isn't clear is it? I've got a few videos on 'diversity' receivers and setups that allow you to have an omnidirectional antenna (like a cloverleaf) and a directional high gain antenna (like a helical or patch) working together to give you the best of both. You just nee to make sure the antennas all share the same right or left-handed setup.. Hope that helps!
You can but the range of the signal won’t be great. Use the same style of antenna or a circular polarised on the model and a patch on the goggles.. best of luck!
quick question regarding fpv antennas i have CP i have LHCP and RHCP does my antennas have to match between receiver and transmitter or can i mix them ?
Thanks for good video. I haev Devo F7 I want modify antenna for bigger range of controll.. which type of antenna I will change to and have some link or picture how I do this modify thanks friends Thanks
+ocular ocular The Devo F7 is a radio transmitter? These antennas are for FPV and there are other options for radio controllers but I've never had to use them. Best of luck.
How to mount/orient the cloverleaf antennas? Should they face straight to the ground or face back pointing to the transmitter when copter show its back?
+FotoAmg AmgFoto You can get away with mounting them in lots of orientations. I tend to mount mine facing upwards but I know many pilots that just have then mounted horizontally too.. Both work great when using circ. pol. antennas.
Thank you! As I checked the radiation grapsh it seemd that if it is pointing to me there is hole... m.modellfluginfo.de/Modellflugzeug-wAssets/img/cloverleaf-antenne.png www.freeblog4u.com/wp-content/uploads/2014/02/Diapositiva1-1_zps7ba0d95d1.jpg as I am in the center of the donut, but if you experienced no difference it could be only theory and I won't worry.
In terms of performance not a lot. You do need to have the same on both the Tx and Rx kit, if you don't then you are actually only seeing the 'reflections' of the signal and they will be of a lower power than the un-reflected ones. Hope that helps..
Those helical antennas, what if you simply turn your head towards the quad doesn't that basically make it 360 degrees if you keep rotating yourself towards the quad?
+William 1 Yep, the only difference is that some use SMA and some use RP-SMA connectors on their kit so you need to make sure you are getting the right sex of connector.. Apart from that it's all easy.
Hi, Painless, nice video as usual. Im gonna build a new 250 fpv quad, and I would like to achieve a good quality signal (obviously, 1 second of signal loss with fpv goggles = crash). The thing is , Im currently using cp antennas in my 450 quad but when I roll or Im avobe myself 90% of the signal is lost. Im afraid that I can lose the signal when doing aerobatics with the 250 quad, so would you recommend a particular model of clover leaf antennas that work well with fast 250 quads? Regards.
Haha, thanks for the advice, Ill take a look, because firstly I'm not sure to spend too much in a rounded copper wire, but it seems different brands really make the difference. Thanks again for your tip Painless.
Why don't wifi router use circular polarized antennas while both uses 2.4/5.8GHz RF? If Wifi control vehicle such as AR Drone 2.0 uses circular polarized antennas, is it helpful like RC FPV? As I understand, circular polarized antennas is invented to avoid multi-path reception. Wifi uses TCP, which can assemble packets in order, so might not need circular polarized antennas. WDYT?
hi just want to say your vids are brilliant..!!i built my first quad last year a cheap chinese zmr and you showed me every step to take, to get it in the air...with sucsess!!.have a quick question my new rig is a rtf nighthawk pro 280...what a lovely piece of kit flys really smooth,using dominator v2 goggles with spironet antennas,But i get a lot of interferance cant work out why,its ok if im within about 30m -40m.surely i should get further....im running on 200mw.... thanks again painless360
+Trent Murray There are many options for diversity receivers. Most will use a circular polarised and helical (for range in one axis) when using a 2 antenna diversity setup but setups that support 3 or 4 are available. The choice of antenna is then up to you on how far and how much coverage of the sky you need.Hope that makes sense. Happy flying!
Thanks for the comment - the pattern of reception is actually like a cloverleaf with the 'petal' that comes out of the front being very elongated (www.readymaderc.com/store/index.php?main_page=product_info&cPath=11_45_49&products_id=227). Happy flying!
Does it matter which CP antenna is on the craft? many say TX or RX.. I assume the RX is 4 leaf, while TX is typically 3 leaf.. but can they safety be switched? (I ask because HK kits come with the 90 degree elbo on their RX CP antenna.. which make goggle mounting look funny.. Thanks!
GMSpada I would go with the stickers on the antenna, FatShark do a range that can be mounted any way (tx or Rx). If you want a right angle then you cam buy an SMA right angle adapter (I use them all the time for neatness!) Happy flying!
Great info, noob here, you may be able to help me, I have walkera runner, it if quite weak, I am trying to find out if the camera and fpv system, that comes installed on it, and plugs straight into the flight controller, is able to be used on another quadcopter, as i want to upgrade, thanks in advance.
+Painless360 , oh sorry, I am asking if you would know anything about the walkera runner 250 , camera and TX setup, if you would know if it would work with other systems, whilst not using the original mother board thing, that it comes with.
The challenge with the Runner 250 is that it's all part of the model so your only option to increase the quality of the link is to replace the average antenna that comes with it or strap a new set of FPV kit on it's top. Best of luck!
Hi, I am planning to get into fpv. Can I use a dipole on the aircraft and cloverleaf on the goggles and still get a decent 'bubble' of range? Reason for asking is that the dipole is more durable and the clover would be safer on the goggles.
It should make things better if the problem is the quality of the antenna you're using. If you have problems with the camera, video transmitter or power system on the model causing interference in the image then it will not.. Hope that helps..
I wasn't going to cover that level of detail in this introduction video but as you asked :) You need to have the same polarisation in all the antennas you use. Brands like FatShark have used right hand for a while and have recently launched a left handed setup. These left handed ones are clearly labelled with a large 'L' and on the circular polarised antennas, use different colour plastics. Hope this helps.
help alot! thank you! but if i want a ground unit (rc car with fpv) what antenna should i use ? (i need somthing that go throgh walls or hills) i got 400mw transmitter and a reciver. ty
WarOfHell 5.8ghz will not penetrate walls, let alone hills. You need lower wavelengths. Not sure where you are but I suggest looking into the frequencies available in your area. Best of luck
whats the cost of patch antenna? I am working a project on Brain Computer inteface. Can u suggest me what type of antenna can be used ? We are gonna extract signal from brain using electrodes and digitalise and amplify it. Then, the signal is to be transmitted wirelessly to a system to extract the information. Application of project could be automatic wheelchair for physically disabled. I would like to know which antenna can be used ?
Heema Sharma Patch antennas are great for long range with a very narrow field of reception. You would be looking at a simple bipolar for short range applications where a wide range of reception is needed.Best of luck.
It's awesome to have people like you to help us learn fpv! Thank You!
Great video, very helpful to a beginner such as myself. liked
Thanks Darren, that's exactly where I was aiming the video at. Glad it made sense! Happy flying!
Thank you! Everyone flying FPV needs to know this right out of the gate. Great info here!
Excellent video, I’m brand new to fpv and you really explained the subject in detail and in an easy way to understand. Thanks much.
you should realize how much i have learned from all your videos. thank you again!

Great video. Finally I've understood the patch antennas!
OMG,for real this is the best review i ever watch,this video help me a lot,thank you so much sir..
Great video!. i just got the v686g and im about to buy Circular Polarized antenna and some pigtails to switch out old antenna.

You video help me a whole lot other videos wasn't so helpful when antennas for my goggles
Hello, What would you recommend for flying with lots of obstacles like buildings and trees?
Most circular polarised antenna work very similarly. I've found the best for places with trees etc. is the TBS Triumph antenna..
And the range on the TBS Triumph antenna is? Low, medium, or long? Thanks.
Same as any other antenna of the type.. The TBS is best on avoiding the interference you get while flying round things like trees..
So the range is about the same as the circular polarized antenna?
Thank you xxtechmoxx and painless360, I was wondering the same thing too.
I realize that it is a very old post, but still relevant & helpful nonetheless, Thank You
hi there really enjoy your videos..very helpfull
Thank you! Happy flying!
thanks for the great information!
Ah right. My quadcopter s antennas are near vertical and my tx is horizontal at the min. so I should have my quadcopters antennas horizontal and my tx horizontal. Hope I got this right thank you for taking time to help me CHEERS!!

This was very helpful, thanks!
Thank you my friend great job!
hi I'm new to this hobby so please excuse my ignorance but can you hook up both antennas both the short and long range
Will a higher dbi allow me to fly behind trees and other objects with less dropout in the video?

drone flying and became interested in aftermarket antenna's when
researching goggles for flying drones. I LIVE IN THE COUNTRY AND WILL BE FLYING HIGH AND FAR , MOSTLY.
It didn't occur to me that both drone and goggles could benefit from aftermarket antenna's.
1st, let me describe what equip. I am interested in purchasing :
Drone : Xiaomi FIMI A3 5.8G 1KM FPV With 2-axis Gimbal 1080P Camera GPS RC Drone Quadcopter RTF - 5.8G FPV

Please see my reviews of the little indoor quadcopters. If your model has a little dipole antenna, then you're better putting linear antennas on to your goggles. I like to use a linear antenna dipole as well as a linear patch if I'm flying one of those. Hope that helps
Hi, love your videos. i have a older system( fat shark dominator with a dual diversity mod set up) so i noticed on my googles the patch antenna is lhcp and the other attenna mad mushroom is a rhcp. for the plane in this setup does it matter if i use a left or right circular antenna?
All antennas need to be the same orientation. Rhcp is normal for analogue and LHCP is usual for HD... Best of luck
Hi. I've got 2 Fatshark CP antenna like you show in your video. Which one goes to the transmitter and receiver? They are the same?
+84npor you can use them either way. Happy flying!
Painless360 Thank you.
Great Video - Thank You!
I have a question though...I have recently purchased a diversity receiver and a patch antenna (as shown in your video). The patch antenna has the sma connector at the rear (to connect to goggles, I assume) but if connected to the receiver, it will point upwards! Looking at your video, I have to assume it won't be as effective even though I have noticed some people have indeed connected their patch in this orientation. May I ask what your thoughts are on this?
Regards
Stuart
The way that I've got round this is by using one of the following two options -
1) buy an SMA extension cable, get a thick one and you can bend it to shape
2) Buy two SMA right angle connectors, plug the first into the goggles and the second into that one so you can mount the antenna facing slightly up (dl.dropboxusercontent.com/u/67301981/Goggles.jpg - sorry for the roughness of the diagram but you get the idea!)
Hope this helps. Happy flying!
Painless360 Brilliant advice many thanks!
Then when people use a circular antenna and a patch together they can fly on a field on a decent range and then when they facing the quad they can go even further? Is this like the typical combo?
That's right. See the other videos in the 'Introduction to FPV' playlist.. Happy flying!
Hi again, I was wondering if you could explain antennas a little for me. Normal transmitter antennas. I'm confused about if I need 2.4ghz or 5.8 and what dbi and gain means and if there's any laws when it comes to it. Thank you.
+Mystical Daptfyie the vast majority of modern radios are 2.4ghz, they use linear or dipole style of antennas for good all round reception. Same principles as the ones we look at in this video.. Happy flying
THANKS great stuff..im new ...what a big help!
+Josh H check out our 'introduction to remote control' and 'introduction to FPV' playlists. Lots of basics covered for new pilots. Best of luck!
ok will do THANKS!!!
please ;i wannt to khnow what a frequence can i take in the 4g for the telephonie mobile not for other applicatiobn just telephonie mobile i need it fo my brief thank you
+Chahinez Drif I'd look at the websites for your local authority you'll find it. A google search will usually let you know too - www.4g.co.uk/4g-frequencies-uk-need-know/
Hi, question, can I use a vertical polarised Panel antenna as a transmitter instead of a receiver. I want to use it for my Phantom 3 standard RC transmitter which gives me hardly any range.
+Rien Diemel I wouldn't. As a panel as its too directional for a transmitter on a model..
hello painless 360 good video it is helping thanks ……. my question is could you use a right hand clover with a patch and or with a helical ,say a five turn r/hand helical for instance and if you had, say the eachine 2000 goggles i think thats what there called …. those new ones you know.could you use patch and helical with clover all at the same time
It's one of those things that isn't clear is it? I've got a few videos on 'diversity' receivers and setups that allow you to have an omnidirectional antenna (like a cloverleaf) and a directional high gain antenna (like a helical or patch) working together to give you the best of both. You just nee to make sure the antennas all share the same right or left-handed setup.. Hope that helps!
Thanks I’m going to check out ur other vids too 👍🇬🇧🇨🇦🇬🇧👍
Can you mix dipole/whip style with CP? i.e. dipole on the aircraft and then a CP on the RX/Goggles. Thanks for the input.
You can but the range of the signal won’t be great. Use the same style of antenna or a circular polarised on the model and a patch on the goggles.. best of luck!
quick question regarding fpv antennas i have CP i have LHCP and RHCP does my antennas have to match between receiver and transmitter or can i mix them ?
+TriniRCmodels no, you need to keep them the same.. Happy flying!
Thanks for good video.
I haev Devo F7 I want modify antenna for bigger range of controll.. which type of antenna I will change to and have some link or picture how I do this modify thanks friends
Thanks
+ocular ocular The Devo F7 is a radio transmitter? These antennas are for FPV and there are other options for radio controllers but I've never had to use them. Best of luck.
How to mount/orient the cloverleaf antennas? Should they face straight to the ground or face back pointing to the transmitter when copter show its back?
+FotoAmg AmgFoto You can get away with mounting them in lots of orientations. I tend to mount mine facing upwards but I know many pilots that just have then mounted horizontally too.. Both work great when using circ. pol. antennas.
Thank you!
As I checked the radiation grapsh it seemd that if it is pointing to me there is hole...

as I am in the center of the donut, but if you experienced no difference it could be only theory and I won't worry.
when it comes to the circular antenna, whats the difference with left hand and right hand, will right hand only work with another right hand?
In terms of performance not a lot. You do need to have the same on both the Tx and Rx kit, if you don't then you are actually only seeing the 'reflections' of the signal and they will be of a lower power than the un-reflected ones. Hope that helps..
Those helical antennas, what if you simply turn your head towards the quad doesn't that basically make it 360 degrees if you keep rotating yourself towards the quad?
You could. That's why antenna trackers are used to do just that.. Happy flying!
ok great thanks for the tip.
Are antenna's compatible with all or most different manufacturer's receivers & transmitters.
WM
+William 1 Yep, the only difference is that some use SMA and some use RP-SMA connectors on their kit so you need to make sure you are getting the right sex of connector.. Apart from that it's all easy.
Hi, I broke the sma connector off one of my spironets. Might you know what size it is and where i might find a replacement I can solder?? Thanks!
eBay and your local electronics store should have them. Most are crimp style though..
Hi, Painless, nice video as usual. Im gonna build a new 250 fpv quad, and I would like to achieve a good quality signal (obviously, 1 second of signal loss with fpv goggles = crash). The thing is , Im currently using cp antennas in my 450 quad but when I roll or Im avobe myself 90% of the signal is lost. Im afraid that I can lose the signal when doing aerobatics with the 250 quad, so would you recommend a particular model of clover leaf antennas that work well with fast 250 quads?
Regards.
+Dashz I'd go for a 'brand' name and mount as far away from the frame as you can... Best of luck!
Haha, thanks for the advice, Ill take a look, because firstly I'm not sure to spend too much in a rounded copper wire, but it seems different brands really make the difference.
Thanks again for your tip Painless.
Why don't wifi router use circular polarized antennas while both uses 2.4/5.8GHz RF?
If Wifi control vehicle such as AR Drone 2.0 uses circular polarized antennas, is it helpful like RC FPV?
As I understand, circular polarized antennas is invented to avoid multi-path reception. Wifi uses TCP, which can assemble packets in order, so might not need circular polarized antennas. WDYT?
hi just want to say your vids are brilliant..!!i built my first quad last year a cheap chinese zmr and you showed me every step to take, to get it in the air...with sucsess!!.have a quick question my new rig is a rtf nighthawk pro 280...what a lovely piece of kit flys really smooth,using dominator v2 goggles with spironet antennas,But i get a lot of interferance cant work out why,its ok if im within about 30m -40m.surely i should get further....im running on 200mw.... thanks again painless360
+TheDok73 yes you should, sounds like interference.. I'd contact the vendor.. Best of luck
Does a diapole antena work with a circular polarized one? one in the transmitter and one in the reciever?
It will work but over very short distances before you will get breakup on the image. I would get another circ. pol. antenna. Happy flying!
Found it, thanks for explaining 👍
Can you use all of the different antennas With different receiveing antennas? Do they all work together?
Kind of. Using mismatched antennas will severely limit your range..
great video
Thanks Dave. appreciated.
is there a diversity device that allows you to combine all 3 types of antenna..if so what do you recommend?
+Trent Murray There are many options for diversity receivers. Most will use a circular polarised and helical (for range in one axis) when using a 2 antenna diversity setup but setups that support 3 or 4 are available. The choice of antenna is then up to you on how far and how much coverage of the sky you need.Hope that makes sense. Happy flying!
Would you use a cp antenna on the craft for the last two applications? So with patch or helical on the receiver?
Yep, exactly.
+Painless360 awesome cheers for the reply.
I am running a 18db patch panel and I get a good 100m bubble around me so good ones will have a bit of side lobe. It was $80. Ouch
Thanks for the comment - the pattern of reception is actually like a cloverleaf with the 'petal' that comes out of the front being very elongated (www.readymaderc.com/store/index.php?main_page=product_info&cPath=11_45_49&products_id=227).
Happy flying!
Does it matter which CP antenna is on the craft? many say TX or RX.. I assume the RX is 4 leaf, while TX is typically 3 leaf.. but can they safety be switched? (I ask because HK kits come with the 90 degree elbo on their RX CP antenna.. which make goggle mounting look funny..
Thanks!
GMSpada I would go with the stickers on the antenna, FatShark do a range that can be mounted any way (tx or Rx).
If you want a right angle then you cam buy an SMA right angle adapter (I use them all the time for neatness!)
Happy flying!
Very good Thankyou!
Great info, noob here, you may be able to help me, I have walkera runner, it if quite weak, I am trying to find out if the camera and fpv system, that comes installed on it, and plugs straight into the flight controller, is able to be used on another quadcopter, as i want to upgrade, thanks in advance.
+DallyDDD Hi, not sure what you are asking...
+Painless360 , oh sorry, I am asking if you would know anything about the walkera runner 250 , camera and TX setup, if you would know if it would work with other systems, whilst not using the original mother board thing, that it comes with.
The challenge with the Runner 250 is that it's all part of the model so your only option to increase the quality of the link is to replace the average antenna that comes with it or strap a new set of FPV kit on it's top. Best of luck!
Hi, I am planning to get into fpv. Can I use a dipole on the aircraft and cloverleaf on the goggles and still get a decent 'bubble' of range? Reason for asking is that the dipole is more durable and the clover would be safer on the goggles.
+Taurusdre if with the exception of patch or helical, try and keep the same on both ends. Best of luck!
Painless360 great, thanks
Nice video
I am having issues with my video signals, does gps interfere with rx or vtx signals
I’ve not had that. Usually power is he first thing to look at..
@@Painless360 Thank you I will look into power source
and the zig bee antennas? x bee antennas? , Z wave antenna? Chips antennas?
This is part of an 'Introduction to' series and recorded over three years ago ;)
Does providing a fpv quad with a good antenna ,drastically improve the fpv quality?Thanks.
It should make things better if the problem is the quality of the antenna you're using. If you have problems with the camera, video transmitter or power system on the model causing interference in the image then it will not.. Hope that helps..
Mister, please tell me how is the law in UK for flying these frequencies and do you need any licence to get for any of those to fly fpv legally?
All covered in the DRONE CODE and OFCOM - all in there.. (www.ofcom.org.uk/about-ofcom/latest/features-and-news/drones-advice)
Thank you, very informative
what about right and left hand circularly antennas, does it matter which one?
I wasn't going to cover that level of detail in this introduction video but as you asked :)
You need to have the same polarisation in all the antennas you use. Brands like FatShark have used right hand for a while and have recently launched a left handed setup. These left handed ones are clearly labelled with a large 'L' and on the circular polarised antennas, use different colour plastics.
Hope this helps.
Amazing thank you soo much! "Liked"
help alot! thank you!
but if i want a ground unit (rc car with fpv)
what antenna should i use ? (i need somthing that go throgh walls or hills)
i got 400mw transmitter and a reciver.
ty
WarOfHell 5.8ghz will not penetrate walls, let alone hills. You need lower wavelengths. Not sure where you are but I suggest looking into the frequencies available in your area. Best of luck
thanks for you answer.
but my rc transmitting in 2.4ghz if i go lower i can find 2.4ghz video transmitter but it will make noise to the video.
specialy 1/4 wave dipole antenna. ??
very informative, thanks
is there not any way to set out satellite antennas throughout your flight area and those antennas bounce back.
Not as such, interesting idea though..
how much range will a Semi Rigid Dipole on the vtx and a patch on my vRx give me?
+Ironiic zero That depends on how well make the antenna is and the power of the transmitter.. Happy flying!
Can I connect 12 dbi helical antenna to my ts832 reciver directly or it will need separate power supply?I am new in this hobby please help.
No antennas are powered. The extra range is achieved by sacrificing the ability to be omni directional. Best of luck!
Hi, I am trying to get into fpv and Ｉ really need some help, so how exactly can I get to the helpout channel?
Check out the 'Introduction to FPV' series and you can post questions in the relevant video.. Best of luck!
whats the cost of patch antenna?
I am working a project on Brain Computer inteface. Can u suggest me what type of antenna can be used ? We are gonna extract signal from brain using electrodes and digitalise and amplify it. Then, the signal is to be transmitted wirelessly to a system to extract the information. Application of project could be automatic wheelchair for physically disabled. I would like to know which antenna can be used ?
Heema Sharma Patch antennas are great for long range with a very narrow field of reception. You would be looking at a simple bipolar for short range applications where a wide range of reception is needed.Best of luck.
Painless360 Sir, whats the range of patch antennas and its gud to use zigbee or bluetooth technology.
If you don't want to do fpv but just fly can you just unplug the antenna and fly with the transmitter plugged in?
Never power up a video transmitter without an antenna attached you'll destroy it. Happy flying!
Painless360 thanks!! You too :)
