Bob,

One possible route for multiple coax cables from belly mounted COM and XPDR
antennas would require them to pass within a couple inches of and parallel
to the electric fuel pumps. Airplane is all electric so one or both pumps
would be running.

Would that likely create an antagonist for the radios and/or transponder?

Thanks,

Allen Fulmer

No, the respective spectrums of interest for both
pumps as potential antagonists and the radios as
potential victims are very widely separated. Further,
the really magic thing about a properly terminated
transmission line (coaxial cable) is that isolation
between the outside environment and itty bitty signals
within is huge.

Not to worry.
