Can anyone help me with sourcing Antenna extensions for both the Controller Transmitter and wifi repeater. Let me clarify: I basically want to fly from inside my RV/Camper..with the antenna mounted up high on the roof with a nice ground plane or pole.. I want to get the longest about 5-7 ft cable from the Controller Transmitter to connect to a Antenna. I've done the wifi range extender antenna mod, and about to do the transmitter antenna mode, but I need an extension from the controller to the 5.8ghz antenna.. FPVLR antennas.. Can any point me or confirm what I need is a long rp-sma extender cable? Ideal would be two cables (one for transmitter, and one for the wifi range extender).
