Hi Dave,
Thank you very much for your message, it is helpful for me. I will run the
transponder
coax on the starboard side together with the feed lines for the strobe
power unit, that is in the baggage area. The comm and the VOR coax' will be on
the port side, in a separate tube that is 15 mm away from the elevator trim
supply. Hope this will be a noisesless layout.
Best Wishes!
Alfred

Alfred,
The transponder buzzes away at over 1GHz and there could be radiation from
the antenna feed cable. It's normally a good idea to keep such cables
separate from the comms and nav stuff.
You can safely bundle the comms and nav cables together and also any DC
carrying wires. There is a risk that the elevator trim supply could
generate noise from the little motor so if you want to play safe, keep that
separate from the coms too.

Subject: Bundling of coax cables
Hi Europa-cracks,
The cable ducts from the rear fuselage to the instrument panel will be one
of the next steps of my building activity. Before I start to do this, I'd
like to know if there is a problem when I put the coax cables into the same
cable duct. I use RG-400U for the transponder and the comm antennas and
RG-58U for the VOR antenna. Do these coax cables interfere with each other
when they are in a bundle? Any experiences and technical explanations from
the electronic knowledge blessed among us?
