i fly a twinstar and i just reached 1.4km with my jr dmss radio, which i think is very poor. therefore i am thinking about placing the receiver and the videotransmitter away from each other. i put the tx in the wingtip but i want to keep the rx in the fuselage. thats why i thought i could just change the aerials. since it is the same plug that would be no problem.

can i get any problems with the longer antennas?
i am thinking of impedance and signal strength (since the cable is that much longer)
