TBS Crossfire modules will switch between low-latency 150hz mode and the slightly slower 50hz mode when needed to maintain a stable link. In the previous video I tested the stock antenna at 25mW and 100mW and noticed a lot of switching. In this video I address some requests from you guys about placing the antenna vertically. The results are very different. Make sure to watch until the end.

Cant beat no Bull, real world tests. What a great place to live aswell.

When you have your antennas horizontally polarized (flat) it interacts more with earth ground. And you need to polarize your quad antenna the same as transmitter.

Hi Ron, been a while since the OCMA races are pretty much dead. I'll reply with what I replied to M Soto here in the comments. They are horizontal because they are purposely placed like that for convenience. I know I'm not the only guy that used to do this. Essentially, the radio fits in the case with the antenna flat. So that's how I kept it. On the quad side, yes, vertical is better. Reason I run a vertically antenna on my long range quads. But on a smaller freestyle quad, a vertical antenna is not always convenient... so basically, the test is to see how well worse-case scenario will do. These days I fly a Tango 2 and on that it's really easy to orientate the antenna vertically. On the quad it stays flat because of convenience.... plus, the way I see it, I'm flipping all over the place, so a lot of the time, the antenna is all over the place and definitely no flat the entire time.

Nice 👌🏼 thnx for the test , definetly running my antenna vertical from now on 😃

@flo-ridafpv5713 4 года назад

A8S fpv works bro, i was 1 of the suggestors for Danny....way more penetration to the sides. N if ya have a metal bar on tx it wrecks signal if horizontal, like qx7... Pawel the inav guy did a test vid few months ago

@janicksimonsen8156 4 года назад

Flo-Rida FPV Damn 🤯 didnt know that , running the Nirvana tho , so no cross bar 😁 But just Got a directional diamond antenna , and gonna hard mount that sucker vertical !🔥👍🏻thnx

@flo-ridafpv5713 4 года назад

A8S fpv cool, i run diamond too, excellent omni pattern, just be careful its fragile

@JoseFPVNavarro 3 года назад

Good video. Good content. Just got yourself a new subscriber. Keep on rocking man.

@PinchTune 3 года назад

Thank you! Things have been a little slow lately, but should be picking up again here shortly.

@StacemanFPV 4 года назад

Yeah, exactly what I have found with R9 as well.. the null points are on the tips, so when horizontal, its more likely to have null points (or close to null points) aimed at/from the quad. Far less likely with it vertical, as the only null points are from the quad antenna, and not both the tx and rx antennae.

@PinchTune 4 года назад

That's exactly right. I'm just going to stop being lazy and turn my TX antenna vertically now every time. Thanks for watching.

@BlueHornetFPV 4 года назад

Love the property... 😍 I've always run mine vertical, or slightly angled. And knock on wood. Never had a fail safe, only once but the antenna was broken at the solder joint.

@PinchTune 4 года назад

Thanks! I have never actually failsafed on CRSF... but I do want the crispiest feel possible, so I want it stay on 150hz the longest. Hope all is well!

@sunsetpark_fpv 3 года назад

I hope that I'm not talking out of school, but I thought for best connectivity both Immortal T antennae were supposed to be vertical. Also, I think the diamond antenna should have been horizontal, and tilted a little upwards rather than facing flat to the ground. I only know this from watching other videos (I'm trying to set my CRSF up). Good tests though, this gives me confidence that I have spent my money on good equipment.

awesome video- I watched the other test too- Thank you!!!

THANK YOU!

@TheMetalSandman 4 года назад

Some things I'd like to point out. -The TX immortal-T in this video with the red stripe, is that V1? Should try the V2. -The Diamond Antenna went to "1" (50Hz) in this video when you were flying to the side more, and flew higher. Which kinda makes sense because Diamond Antenna's signal is stronger when flying in front of it. Also flying directly above yourself with vertical orientation means the drone's antenna is facing your TX antenna's null/weak point, so those results definitely made sense. -The "receiving" Immortal-T on the drone should match or be as "parallel" as possible to the transmitting antenna. So if your TX immortal-T or Diamond Antenna is vertical, so should the drones, as much as possible. I read that once I think on the TBS Antenna Orientation Guide on their website. If they're lined up "perpendicularly," signal ain't as strong! -Great informative video! I was curious about this, and I subbed! :P

@PinchTune 4 года назад

Hi! Thanks for the feedback and the sub. Yeah, you are absolutely right. In fact, Mike Chin over at TBS also said one should make the orientation on both the quad and the TX. I'm just happy with knowing that going vert on the TX made such a big difference even with the flat antenna on the quad. It's a compromise I'm willing to make, as a vertical antenna on a freestyle quad is a bit of a pain. Now, for my long range stuff, that's different. I do have it vertical on my Super G (on flat, the other vertical as it's diversity) and will convert my long range Alien to vertical all well.

@TheMetalSandman 4 года назад

@@PinchTune Thanks for testing the Diamond Antenna, too. I got worried you weren't going to because you said that you're not going to bother with the other antenna at 5:01. Also, SICK flying! I'm fairly new to FPV and I definitely can't do all the tree dodging maneuvers you were doing!

@proz71ful19 4 года назад

Hey man.. your cat was chewing on lipo leads 😂 cute kitty

@PinchTune 4 года назад

Proz71 Ful Haha. I have some crazy cats. Luckily none have gotten shocked yet. 🙀

@flo-ridafpv5713 4 года назад

Cool glad ya tried it, my diamond on R9m vertical gives way more penetration off to the side, thru cars + concrete much higher rssi

@PinchTune 4 года назад

Test successful if you ask me. Just knowing that going vertical makes such big difference. BTW, I haven't ordered the VAS antennas for my DJI goggles yet. I'm watching my spending.

@flo-ridafpv5713 4 года назад

PinchTune yep, i tested at 10mw on R9 with amber callouts, big diference. Cool we all are now, or should be lol. If ya wanna test tennas ya have just order adapters, pagodas work great on goggles too

@ChrisGripeos 4 года назад

I was waiting for the cat to push the quad off the rail... that is a good cat..

@PinchTune 4 года назад

Lol. She’s a good cat. Really sweet too.

@DjangoFPV 4 года назад

Thank you man!!! I’ll change my antenna position ✌🏻

@PinchTune 4 года назад

Im going to stop being lazy and turn mine vertical every time I take it out of the case. Haha.

@DjangoFPV 4 года назад

Up to now i always adopted combo like this: orizontal on the quad orizontal on the radio. But i know that is better to change to vertical on quad and vertical on radio, because, the end point of antenna do not cross each other.

@FRY_FPV 4 года назад

I use the truerc antenna which is specific to 868mhz. The TBS antenna are actually designed for 900mhz in order to be used for 868mhz and 915mhz users. Maybe try to compare your range with that TrueRc antenna specific to the frequency you use to see if it makes a difference

@PinchTune 4 года назад

Ah interesting. I'd have to find one for 915mhz if they make it, given that's what we use here in the states.

@angelfpv4825 4 года назад

subbed! more testing!

@PinchTune 4 года назад

Thanks, looks like I have more testing on order. :)

@syedmuhdakram8450 4 года назад

The cat smells your quad 🤣

@PinchTune 4 года назад

That's what she does :) Haha

@davesfpvfiftyfiveco.7716 3 года назад

I don't think the diamond was better?? you also stayed in the same spot right in front of you the entire time and didn't go far down the hill like the other tests...... just my opinion. Good stuff tho

@PinchTune 3 года назад

Possibly yeah. I was mainly paying attention to the call outs if I remember correctly. I wasn't sure it did better, and if it did it was marginal. Maybe longer range it might make more of a difference. I'm flying Tango 2 now, but I'd like to do a test like this maybe long range. But the firmware has changed so much since.

@TERBANGFPV 4 года назад

using BF 4.2 RC now the link quality osd can shows crsfmode:LQ eg: 1 or 2:100.

@PinchTune 4 года назад

Ah that's cool. Good to know. That can be pretty useful for long range. I had originally set this switch up like two and a half years ago when I started flying long range. After that I didn't use it for a long time until I realized it could be useful for these short range tests.

@TERBANGFPV 4 года назад

PinchTune yeah

@porroco 4 года назад

Wonder why not leaving power in 500mw and forget about it.

@PinchTune 4 года назад

Several reasons... 1. It consumes too much power. 2. I can introduce noise into other electronics around (speaker, video cameras, phones, etc)... but the biggest reason is 3. Etiquette. You really should only use as much power as you need to get the job done, when it comes to radio signals. You don't just blast more than you need and call it a day.

@itthisak99 4 года назад

tx version. 3.28?

@chenhaus 4 года назад

Have you tried taking off the frsky 2.4ghz antenna? It sounds crazy, but I noticed it affecting my range even though it’s not active. It is grounded and probably acting as a really crappy yagi.

@PinchTune 4 года назад

Oh wow, I never even thought of that. I would have to mod the radio to take it off because this SE radio is one from Aloft Hobbies, and their special order didn't have removable 2.4 antennas.

@chenhaus 4 года назад

PinchTune Yah I would give it a try. I also found the diamond antenna to have less open range than the standard T, something our safety pilots at work noted as well. The little 2.4ghz diamond antenna is a major improvement for whoops though.

@llickmogan 4 года назад

I run mine vertical and at 50hz mode

@OnepackFpv 4 года назад

What gimbals are those?

@PinchTune 4 года назад

They are the red FrSky M9 "R" gimbals that are normally used just on the throttle. But I used them on both sides.

@skirmich 4 года назад

Off topic.. If you are going to put music like that? Normalize the volume across your video, Music was way louder than everything else.

@PinchTune 4 года назад

Actually, not off topic. I actually did normalize the thing, but I think I could have done better. I kept going back and forth on it and just let it slide in the end. I reduced the track volume on the loudest parts by -2 db, and of course I reduced it to -28 db when I started talking. I think my issue was actually that I needed more compression and boost to my voice. It's tricky to do when the mic is on the camera, as I lose a lot of punch as compared to a lapel mic or a mic on a boom. Thanks for bringing this up though. I'll try more voice compression next time and hopefully that'll make it so the listener already had the volume lower before the music comes on.
