I am also an electical engineer, a long time HAM and years of testing instrumention much of it in the RF area. You are not like to get in trouble with parallel runs with wire leads regardless of length on the frequencies we use (unless we get into the gigahertz range) or are very titely coupled (less than a quarter inch). You might possibly get some microsecond periods of antenna blanking but even that is unlikely and will never last long enough on a moving object to ever even know it. Note: this does require that the ends of the wire leads are isolated electically from each other and the airframe.
