FrSky Range Problems

HI!

I transformed my Graupmer MX16s with the FrSky V8HT DIY Module FrSky V8HT DIY Moduleto a dual (35MHz / 2,4GHz) Transmitter. I can choos, if I want to use either 35MHz or 2,4GHz.
So far so good, BUT I have range-Problems while using it in 2,4GHz Mode.

When I use a V8H4 Receiver (I have the same problem with all of them), the range is not that good as I expected.
I wanted to use it in a little parkflyer (508mm WS).
But after about 50-80meters, the connection broke, and my flyer crashed.

What can be the reason for this? I heared, that this little receiver can be used till 500 meters and more.

How can I check why this happens.
Can I increase the power-Output?
Is there any hint, how I could solve this problem?

Thx Mike

Yesterday i did a real range-test.
I put my transmitter in range-test-mode and went away, moving the sticks.
As the manual said, it should be possible to walk about 30 meters till the connection breaks. After 3-5 meters, the servos stoped moving.

Without the antenna, they stopped moving when I was 2 meters away.

Then I hat the idea, to change the antenna, AND nothing more to say, IT WORKED VERY WELL !
I could walk about 85 steps and the servos still moved the right direction :) (of course still in range-test-mode)

So the reason was a damaged antenna.
I used a WLAN-Antenna fom a Cisco WAP200 and it worked very very well.

After that, I could fly 3 accus withou any problems and without a crash :)
Maybe, only maybe some of my crashes was not caused by myself :)

hi
j have the same problem
range 5 meter in test range
j resolve the problem :

change your tx antenna, in my case, NO CONTACT connector antenna ! please verify that your antenna can turn 5 or 6 turn on his base..
when j mount Spektrum antenna, range is ok

Make sure you're using the correct antenna and inspect the cable and conector that comes out of the DIY module.
I had the same issue due to the cable been damaged, eventually had to buy a new one.
