i find my 57mhz rx7 gets about 8 metres, which is not bad.
i also have 35mhzand 45mhz boosters, and they both only reach 3-4m!!!
gave them all nice long new cat5 antennas, and it didnt make any noticeable difference. i also put a longer wind-up wire on the booster controller, but that did not change things either.
the next step is to find a telescopic antenna that will fit nicely in the controller! (been looking but have not found anything yet)
