I'll see if I can take a video today,I'm working on my Goodluckbuy s Osd module.
I have two transmitters ,a 1.3 ghz 1500 mw unit and a 2.4 Immersion 700 mw . I have the Immersion hooked up now. I had the 1.3 ghz on the Phantom for a while,I think it was too powerful and too close to the Phantoms reciever and caused a few return to home issues at about a 1/4 mile. Very strong video though. I tried the 2.4 at the same distance and did not have any problems, video was not as good. At 1/4 mile I couldn't see the Phantom ,so that's far enough .
