By just putting an antenna on the repeater I'm getting well over 3000 ft
Haven't done anything else
Good luck

Stock P2V 2.7 KM (8,850') Long Range Test
- Thread starter PVFlyer
- Start date
WIth an omni and a directional on the repeater, and powering it, I am getting 3000-4000' easily and have flown to over 6000'. Also altitude of over 4000' with full wifi and control. At 6000' it was dicey and I pushed it more and lost both wifi and control. I let it fly itself almost all the way back - smooth as silk @ 16mph.
https://www.youtube.com/watch?v=yvTIeJO2qeE - at just after the 4 minute mark it loses it @ 6142' and starts the return home.
I am very happy with this performance for normal flying and don't need more, but am thinking about doing the Horizon Antenna kit anyway. Just because.

Wow. Those are some great results effectively just by improving the antennas on the ground side. Perhaps DJI are missing a trick?
Anyway I've done the tx mod and the extender mod now and all went well. Not able to flight test yet but I went to the bottom of my garden and from 130ft away passing through a shed and through a conservatory I had a control signal and perfect preview via WiFi so it looks good that I haven't fried anything!
Thanks for your help and hopefully this should improve performance. I've left the aircraft end of things for another day but will tackle that tricky receiver mod at a later stage.
I did a quick first impressions video this morning of the Horizon FPV gear before I fit it and it's very nicely made and very light. I'm not bothered by aesthetics so I didn't go for the all-white to match the tx!

Pull_Up said:Hello long-range gurus. I bow to your superior knowledge and excellent homebrew achievements!
Now I've buttered you up I would like to ask an opinion of you.
I'm not after extreme range from my Vision, but I would just like to stabilize control and wifi (at the moment I tend to get a max of 1000ft for both, but it's variable sometimes drops out whilst I'm still visual with the aircraft which is what I'd like to improve).
So I have got one of these kits: http://horizonfpvantennas.mybigcommerce ... -full-kit/ which has matched antennas for ground and airside for max performance that are all LHCP. Now until my soldering skills are up to scratch, and until my gimbal arrives and I know about antenna placement, I'm wondering if I will see any benefit (or at least not see any downside) if I just fit the helicals on the ground side only for now? I notice that a lot of the mods in this thread are keeping the aircraft almost stock but I notice most effort is going into the wifi side as you all seem to have much better 5.8 performance than I do.
The big issue for me going forward with installing this full kit is going to be the receiver side as although the kit comes with pigtails, the stock antennas appear to be hot-glued or similar to the receiver board. So I either need a hint on how to take one off safely or I need to learn/find someone to do some fiddly splicing and soldering for me!
All information/hard knowledge/guesses/assumptions/speculations gratefully received.
DJI claims 2.4G Wifi FPV with 300m range and 5.8G control (FCC mode) with 500m range. I tested my stock P2V and repeater/transmitter with 300-400m FPV range and 800-1000m control link in open field.
If you tend to get 1000ft (304m), the stock setup should be good enough to meet your requirements marginally "in open field". I suspect you are flying in urban area with a lot of 2.4G interference. I have a few questions for diagnosing the issues.
1. Did you test your stock P2V in open field with fully charged repeater & new batteries for transmitter?
2. If yes, what's the range of 2.4G FPV and 5.8G control link? I bet the 2.4G Wifi link dropped out first if you have proper antennas orientation, so you probably don't know the 5.8G control link range. I believe you know how to position both antennas properly. This test is to eliminate RF hardware issue.
3. Is there a lot or strong 2.4G Wifi along your flight path? You may use Wifi Analyzer (free Android app) to check your Vision camera & repeater Wifi channel (such as Channel 1 in my case as shown below). Then walk along your flight path together with Wifi Analyzer and see how many Wifi AP with the same channel as your Vision, and how strong they are. This test is to identify how much Wifi interference in your flight path. If all your neighborhood using high power repeater (like the common 1500mW ARGtek in this forum), I'm sure your range is way lower than in open field. Obviously, other 2.4G may also generate interference. We live our life at 2.4GHz. Your router, your cordless phone, your Bluetooth earpiece, your baby monitor, your garage opener and your kitchen all on this radio frequency.
I suggest to identify where are the issues first, and then address them with the most effective way/mod. Your 1000ft target should be easy to achieve without modding your P2V aircraft.
I can’t agree more of a FPV guru saying “Some hobbies you can buy your way to success. FPV is not this way. Don’t try it. Understanding is what makes success, not money.”

Hi, thanks for this.
Antenna orientation, battery condition - yep all good.
I fly in open countryside mainly, but with plenty of trees, hedges, grass and small hills.
WiFi I get about 1000ft which is on the money, although it starts to get a little flaky then and I might need to change orientation a bit to keep contact at that range.
5.8 I lose at 1000, sometimes 800 ft in the same sort of terrain in FCC mode. I suspect the natural clutter (wet trees!) isn't doing me any favours, hence looking to improve antennas. As I said I'm not looking to go extreme, just firm up both signals so I can operate at the edge of visual range for filming purposes.
I will report back when I've tested the tx antenna out and let you know.

for an eXtender best to get a Linksys E3000. Stock output is close to 996mW and you can sNatch them up for $40 bucks. Add your own antennas.
I would not gamble on the knockoffs!
These flying saucer looking routers are ugly but powerful and easy to mod fro great performance.

If you are operating close to tree, LoS is based on your transmitter instead of your eyes. You probably hold the transmitter 2-3' below your eye level.
You may also consider Fresnel zone effect below, but I doubt how Fresnel zone affecting only 300m range at 5.8G.

Ok, so I managed to test it out this morning. I put a post on the Horizon FPV specific thread: viewtopic.php?f=7&t=9092&p=77566#p77566
Executive summary? With stock aircraft and Horizon 5.8 & 2.4 antennas on the ground side I got a 100% tx range improvement, and a 50% wifi range improvement (that was with the camera facing directly away from me, yawed sideways it was more). I tested it in a place I had previously flown in for a fair comparison of range.

Nice video and nice work.
A proper built parabolic reflector (AKA windsurfer) should increase 3-6 dBi gain, which is equivalent to additional 40-100% range. There are some DIY 2.4G templates (PDF) of parabolic reflector available for download.
managed to get a range test in today on my stock p2v in FCC mode
200ft up and 1695ft in a straight line out before I lost signal I think this is about right on a stock p2v
200ft up and 1695ft in a straight line out before I lost signal I think this is about right on a stock p2v
About 600ft more than mine could ever get stock in FCC mode. I think my part of the world has just been too wet - isn't moisture supposed to be bad for RF reception?! Still, my little 5.8 helical has pushed that out to 2000ft which is more than I'll ever want to use.
Mind posting a picture of your current setup?Pull_Up said:
I'm using two 9dbi omni (ducky) antennas. And get consistent 1200 with zero interference and full reception.
Understood that's very low and insignificant range but previous stock test was losing control at 500 feet and video at 800.
Sure. Here's the video of the install - http://www.youtube.com/watch?v=NsUpYNeTwaU : the final setup is shown in the opening sequence. Links to everything in the description.
