glitching with mmm combo

[ReV:-O]

oh right i see. i have a spektrum DX3 (the first generation one) and the MMM combo. whenever the revo gets to about 100m or more away from me, the radio looses signal and i have to move nearer. what could be done with the wires that would help this? i dont really want to cut them, so should i just try and make sure they are as far away from the receiver as possible?
