shielding advice needed

I intend to route some wires and cable inside both sides of a radar arch I'm installing (2 1/4" ID) for the VHF antenna, nav lights, radar data and power, GPS antenna, plus some power for small deck lights. I would appreciate any suggestions on products available or methods to sheild them when run together, and the best choices for dividing them between two vertical runs. thanks.

Ideally you would run power down one side and signal cables down the other. Failing that I'm sure I've seen some flexible sheathing that screens the cables.

That would seem the most logical, but the literature suggests there is also a possibility of interference between the radar, vhf and GPS antennas - which is what I would like to avoid. Are you familiar with any sources for flexible sheathing or conduit that would do the job? I've checked local electrical outlets but find their materials wouldn't suvive the salt water environment.

We're talking about DC power here, so I think separating them is not really critical. I'd be more concerned with high frequency signals migrating between cables, but most high freq cables are already shielded.

How about laying everything out before pulling cables, bundle them together, and see if you have problems?
