Transponder antenna - blade vs stub monopole

At 1,000 MHz, RG-58 has a loss of about 15 db per 100 feet. So, a 10 foot
run would represent 1.5 db. That is an acceptable loss. It will reduce the
range a bit.

Generally, if the control cables are not resonant and not in the same plane
as the antenna (horixontal controls, vertical antenna), there should be
minimal interference. There are a number of antenna plotting programs arund
that would allow you to plot the potential interference. to determine the
possible interference.
