Don't see why you can't bundle them together - they are all
individually shielded. I bundled my cables together and notice no
interference.

I am starting to fabricate the following antennas for the rear
fuselage:

transponder

comm 1

vor/glideslope

marker beacon

My question is can I bundle all of the coax into one run forward, or
should there ideally be some minimum separation from the cables in
order to minimize any interference from one another.

Thanks
