Glad to know you are increasing 70-80% FPV range. In general, 3G antennas would not interfere 2.4G Wifi, while 3G bands are usually from 900MHz to 2.1GHz.philarvropagan said:No worldwide record to mention but my own one tonight
1.320m (4.330 feet) with the WiFi Booster while I got used to less than 700-800m on the same way.
640x15fps FPV video.
Weather not so fine : no wind but heavy grey sky with high humidity rate (should rain again in a short while).
Free of interferences ... but 3G antennas on a water tower 400m on the right.
Stock P2V+ but a brand new home made parabolic reflector on the TX antenna (made following a real parabolic shape I prepared on Excel).
Very happy with it as it works as expected and calculated (8 to 12dB gain but not to much in order to keep with a wide enough beam).
So everything's fine to me as I never tried to beat records but to secure my flights within a sufficient distance to hover over small rocky islands in the sea by here.
Shall the 7ch mod come and I'll be the happiest Phantom guy of ... my village :lol:
One more time, thanks so much PVFlyer !

Yes smb, it looks so ... but I have tuned the values.Smb said:
No problem at all. Regarding SWR, I used a low end 2.4G SWR meter to measure my homebrew LHCP helical last year. SWR is not a very crucial factor for antenna performance. There is no notable difference between 1.1:1 and 1.5:1, as long as it's not too bad something like 3:1 to 4:1. I tuned my homebrew helical SWR to 1.09 (the best I got 1.05) was just for fun.philarvropagan said:Yes smb, it looks so ... but I have tuned the values.
If you take a look on the shape I've drawn : https://www.dropbox.com/s/z1zw214h456a0ew/ReflecteurParabolique.pdf
k=0.2
This ratio fits well omnidirectional sources and moreover, gives a focal point at 20mm which is convenient
- not to deep into the parabol and so, still let the beam a little omnidirectional
- easy for the design
with c=30 mm, the antenna is not too wide and deep.
But i'm pretty sure that widsurfer ez-12 will provide a good result as well.
An important thing to me is the relector which must have a clean and smooth surface (that's why I took a can of fruit juice ... but one of beer should also work :lol: )
... and sorry for this post PVFlyer, which is out of this thread concern
There is another thread for that, http://www.phantompilots.com/viewtopic.php?f=27&t=18157 but I was wondering about the theorical approach and the resulting SWR.
That's why I made my own one (based on my experience, by some web surfing and by other designs like "windsurfer").

That's a great range for stock P2V. What preview quality did you use? What was the range (same flight path) with stock RE500 repeater?Mal_PV2_Ireland said:
I'm using highest fpv quality since the last app update, before that 700m was about my best but very hit and miss. My p2v has always been a monster for distance from stock for some strange reason, im not complaining. The 1.3km distance was on an island beach with zero interference, cant replicate that in urban areas. I'll try the app anyway but does the app boost the re700 or the camera?PVFlyer said:
What went wrong with the recent deleted/edited posts? I think they are acceptable, unless I missed some very inappropriate posts. I understand we need somehow to draw a line, but we are not living in a royal family. Guys (most of us are male) sometimes may say/write something emotional, rude or even mad, which is common in any forum. Just my 2 cents.Geert said:
