    Hey guys,

    Take a look the 2 green arrows at the bottom in this picture. Can anyone tell me which antenna port is for the 2.4GHz RC TX and which is for the Video RX (5.8GHZ?)

    Did you use a spectrum analyzer to verify?

    I doubt that both video and control are on the same frequency.

    Can anyone else verify?

    I thought they (P3P/A) were MIMO, in fact sending control and video via the same 2.4 GHz frequency.

    Someone will confirm.

    This has been studied by myself and others.

    Video is transmitted in a 10 mhz wide signal, and the control signals is some sort of frequency hopping spread spectrum.

    Both are within the 2.4 GHz ISM space.

    I discussed my findings with an rf analyzer here: Phantom 3 Channel <-> Frequency Table | DJI Phantom Forum

    I do believe though, that one antenna is transmit, and the other is diversity receive, but I haven't had a chance to prove this theory yet.
