- Thanks for watching ! I really enjoyed making this test.
Linear antennas come free in any and all TBS Vtx's, but they were actually more expensive than I thought when bought one at a time. 300 whole pennies! haha. Still significantly cheaper than CP of course.

It's good to know that no matter how expensive your antenna is, with hdzero, your signal is always shit
Although i definitely disagree with the statement and think HDzero is incredible for some use cases, this made me absolutely crack up hahaha
@@headsupfpv racing around a flat field with plastic poles is a good use case, however it seems it's the only good use case. The second you wanna fly around the real world. The video signal is really really terrible. I spent around 2000 euros on hdzero gear before I finally gave up on it and went to DJI. I just couldn't justify buying more gear for it when the results were always underwhelming. I got fed up in the end.
@Sh.tPilot fella there is no real world flying is flying
@@obreezily Absolutely wrong. Not all flying is the same.
If you're flying in an arena you can guarantee what is in the arena and what isn't. If you're flying outside somewhere, you've got trees, water, atmospheric conditions, all kinds of obstacles of incredible variety of composition.
So no, absolutely not, "flying is not flying"
Unless the results you want are super low latency, crystal clear signals in real world racing scenarios, then you're right 🙂 DJI way better for long range and penetration, but not latency b@Sh.tPilot
I love this type of testing. $1 FPV gear all day long
Same! Thanks for watching
Also, if you want to evaluate linear antenna perf with hdzero, unscrew all but one antenna from the goggles. Place the drone far away and then tilt your head side to side to observe the null points. The goggle places the 4 antennas at different orientations, which counters nulls
Great tip! I'll give that a shot. After doing some more research I started to understand why the HDzero goggle antennas are mounted the way they are
@@headsupfpv That still won't stop me from running random antennas in random orientations
@@tehllama42 🙈🙉🙊
The transmitting dipole still has 2 nulls out there, but the dB is so low they're probably not very significant.
Love it! 👏
Great job Evan! Thanks so much for this!
Glad you liked it! Thanks for the support!
Great video! I still run DJI V1 goggles, I was sick of replacing antennas on my bashers and started using the walksnail liner antennas on my Vistas.(over a year now) I hardly ever break them now and where I fly I notice little difference so it works well for me
I think you’re onto something dude!
Great topic . Definitely need to see multiple pilots on linear at the same time and see how it goes
Definitely a future test!
A durable well tuned linear antenna is better than a fragile so-so polarized antenna for racing. With digital OFDM modulation I don't think alternating rhcp lhcp is necessary. I want to see some 8 up testing with hdzero using linear vs circular polarized antennas
I’m gonna make it happen! Super intrigued
@@headsupfpv awesome. I'm really looking forward to this. It's not something I can test by myself
@@headsupfpv I think the VRX antenna is also relevant. Will you use a linear antenna on the VRX as part of these tests too?
@@headsupfpv you're going to ruin the antenna market 🤣🤣
@@RyanQuellet another thing to test would be how they compare in high multipathing environments
i got told if you use cp antenna on vtx and vrx, multipathing interference are attenuated drastically because reflected signals would change their polarisation.
For tests like this it would be awesome to have one quad carry two cameras + vtx's at the same time. One sending on R6 and the other on R8 (highef frequencys to stay futher away from wifi) So changing interference from external sources is eliminated. First test and compare both with the same antennas and switching up channels, if there is no significant difference in reception then test linear vs cp also on both vtxs and channels
Tanks for the info.
Thanks for watching!
@@headsupfpv 👍
Great video thank you
Thanks for watching !
This was great vid.
I’m glad you enjoyed ! Thanks for watching
Very interesting and informative test video. Cheaper and lighter weight. Worth trying, especially on smaller builds where you want to save weight. Happy flying everyone.
I’m glad you enjoyed it! I was definitely surprised by the test. Happy flying to you!
I'd like to see more drones up in the air with the whip antenna
I’ll try it!
were you running linear on your gogggles during the linear antenna test?
I used identical antennas setup on my goggles for both which were CP. maybe I need some linear ones to try!
@@headsupfpv aww man for sure, just slap on a pair of dipole (rubberducky) antennas, they will give you at least 30% more reception on a linear dipole. If you want to go even further get a linear patch antenna. Long range fixed wing type FPV people have been using these types of antennas for years for long line of sight flights.
If you have linear antennas on your quads, should you use circular polarized antennas in your goggles anyway?
This is what I don’t know, I’d guess probably not?
Hey, I got a question, I bought a Mobula6 from you guys a while back, and now it is behaving a little weird, when flying under 30-40% throttle it's all good, but when over, it shakes a lot and apparently the motor do some dips in rpm... it is annoying me a lot... what could be the problem?
Hmmm, I’m not sure off the top of my head. Shoot an email to support and we will absolutely get it figured out!
do you have the stl for that dual purpose antenna mount?
Yup! Right here. www.printables.com/model/243738-five33-lightswitch/files it’s the core 5.8 file
When I started flying I had only linear antennas and I noticed that having linear antennas on both the quad AND the goggles was way better than mixing linear with omni.
Interesting! I’ll have to try this
I'll be surprised to see this working well. The loss of running linear and circular together shouldn't be more than 3 dB, which isn't much. Compared to the loss of two linear antennas being out of phase with each other, that's more like 10 dB. That said, having 4 linear antennas oriented differently on the receiver might avoid all situations of two linear antennas being out of phase.
All of the DJI o3 and o4 systems use linear antennas as well as on the goggles fly fish makes a linear antenna for the goggles that has better directional gain to boost los range
Off topic, Are you all updating any of your BNFs with the new HDZERO FC?
Answer, yes!
@@headsupfpv sweet! I
Look forward to ordering one when the change happens!!
I JUST ordered some foxeer lolipops to replace my linear antenna lol
I was told to expect a night and day difference but you just made me question everything I've been told about them.
lol! I’m sure your performance won’t be worse, and will play nicer with other pilots!
Linear on VTX is only a slight issue if you are using a single linear VRX antenna without any diversity. HDZero uses 4 antennas, and unless you change them all out with a single linear antenna it won't really matter.
I literally just solder a 13mm wire directly to the VTX on my race and freestyle bashers. That way I never loose antenna/video signal, and it is the most durable setup, by far.
This is pretty cool idea and super cheap!
@
Something I have been testing for about 8 months is running a standard circular polarized antenna and a piece of wire directly soldered to the board, at the same time… I have had multiple midair’s and crashes where it has taken out the primary antenna, it’s coax, or even the whole ufl connector, and I didn’t notice until I looked at the quad after I landed. I don’t know the long term consequences, and haven’t talked with an RF engineer yet, but so far so good.
For freestyle, I run linear on some of my O3's, especially for sub250 builds. Very little difference seen outdoors. Occasional issues in bandos with penetration, but still flyable.
And for the price it’s so worth it!
I always felt like the 2g weight penalty is heavy for maybe a little bit better signal on tiny whoops at least
On whoops linear all day!
For racing, wouldn’t you want the lightest one vs a circular one?
Definitely! But have to use the lightest also with best performance, and that’s where lines struggles is with multiple transmitters. I’m going to test regardless!
The video you've linked to by IBCrazy actually compares using linear antennas at both ends (TX and RX) vs using a circular polarised antenna at the RX. My guess is your tests with the linear antenna never actually reproduced the linear to linear problems since you probably had circular polarised antennas on your goggles. So you were actually reproducing his 2nd experiment where one end is linear and the other is circular. So it's not surprising you didn't notice much signal degradation with a change in orientation since this is what IBCrazy demonstrated. IMO the test you should have done is in an environment with lots of multipath reflections (e.g. A metal warehouse) since polarised antennas at both end would give better multipath rejection.
Will absolutely be doing another test similar to what you described!!
Where’s not sure 👀
Not ahead of you that’s for sure!
Where r u buying them for $1????
Link in description!
@headsupfpv thx mate, but id rather pay lil more and buy from US company. Great vid tho. Definitely not upgrading the cinewhoop to rhcp
I’ve been saying for years that the 1mm of copper going left or right in these new antennas isn’t doing much. Same reason I run both left and right antennas on my goggles and never change them
I think you’re right!
And here I am running a left and right on my goggles, with linear, right, and left on different quads.. Been doing this since I started in 2017-18..
You are ahead of the game!
@headsupfpv appreciate that.. Keep posting videos like this, the community loves it..
Not gonna lie the true rc singularities i grabbed aren't worth it over an ORT or whip antenna at all.
I tried HDzero with plenty of antenna’s and Lumenier AXii work the best. TrueRC antenna’s are simply hyped and their performance is nowhere close to Lumenier.
Interesting ! Doesn’t true RC manufacture for Lumenier ?
Lumenier is made by TrueRC.
As someone who has broken many Lumenier antennas I can confirm it’s a TrueRC antenna (name and all) under the Lumenier housing
"for a standard race with only 4-6 pilots in the air"... we would still be racing 8 up if people would just correctly follow the L & R channel assignments. But I need to save $15 and not by both a R and L when I go to an event I spend $100's of dollars for entry and travel... because I am smart.
lol! I’m planning a test to compare performance across linear and RHCP / LHCP. $14 per drone isn’t nothing but ya us racers always spend far more on travel haha
yesss,,, we need to break the legend of antenna polarization myth,,,maybe the issued of linear because the DJI use linear antenna,,so dji send the expert/influencer to tell the rest of video system just focusing on RHCP and LHCP, while dji using linear polarization,,hehhe,,it just not so serius conspiracy A.K.A joke..
That discount has reached its usage limit. :(
Gotta be quick ! We will have another hidden in the next video
