How important is separation with 433mhz rc rx and 2.4 ghz video tx? I know that separation is key with 1.2ghz video and 2.4ghz to minimize harmonic interference, but I am wondering if the same applies to the aforementioned system. I am only getting about 200 meters with my 2.4ghz 500 mw video system which is very strange. However, my antennas are only a foot apart on the plane so that might be a problem, although I doubt that is why I have such a reduced range (foxtech advertised as 3 - 4 km). I am using standard dipole antennas for both. Would adding a coax extension cable to increase the distance between the two antennas be significantly beneficial?
