Got my circular wireless skew planar antennas today. Had to test the out immediately and the video explains everything else :D The distance i got is pretty impressive since the video TX is not really mounted in the optimal place for transmission and the area i was flying was not that free of obstacles. My gopro probably blocks the TX signal when the phantom turns around = have to relocate TX. Stock fat shark 250mW video transmitter was used. The phantom transmitter did not have any glitches what so ever. I used a "windsurfer" antenna booster for the phantom TX which helps out the signal ( most likely not even needed for this distance ).
