After reading a lot about different long-range systems, I decided to go with the EzUHF from Immersion....best support, widely used and totally compatible with my EzOSD and Immersion Tx / Rx....

But you have to be aware of a few things:
The best Long-Range system doesn't help you if your Video down-link can't cope with the distance....in my case (5.8 Ghz 600 mW Transmitter and Dual Receiver V2 from Immersion) I can get a good range, depending on the enviroment, within line-of sight....but then it's over. So to increase your video-link, you need a good antenna tracker (I got this one:
http://www.myflydream.com/product?id=1&name=12CH-AAT-Package) and special antennas (cloverleaf and/or helical).
To set up the Naza on my TBS disco with the EzUHF and my Futaba T14SG was a never-ending nightmare.....I tried PPM connection (one cable like S-Bus), I tried PWM connection (traditional, one cable per channel)...nothing worked. Then I was reading I have to up-date to the latest software/firmware version....I did....same crap as before. Problem was, the stick input would never center in the NAZA assistant.....I was reading every post on the EzUHF support forum:
http://fpvlab.com/forums/forumdisplay.php?22-ImmersionRC....tried a million different things....no success....although with the PWM connection I got better results than with single cable PPM....I was close to throw that stuff against the wall.....funny enough, other people reported it worked straight out-of-the-box...
Than I found this:

Got it from Denmark.....hooked it up....worked straight away. The beauty is, you can actually use any Radio (Futaba, Jeti, JR, Turnigy....) with this system. It's proven to work with the Immersion EzUHF.
The reapeater is hooked up with the EzUHF + Frsky TRF8 + a power supply:

5V 9V 12V output, 10.000 mAh !!! for the price of $ 50...no Lipo can beat that.
Set-up looks like this: (obviously without those stupid LiPo cables)

Big +: no need to strap the UHF transmitter to your radio, and it works.
Forget that damn "What's the best ?" approach....just get your share of back-ground knowledge and then decide.....and don't expect the whole thing to be just plug-and-play .....
