73 Airstream 29' Land Yacht - Routing Coax Cable

[LouK]

Sure hope someone can help me. We are updating a 1973 29' Land Yacht and I am trying to find a way to fish the coax from the new center of roof antenna down to the box next to the refrigerator. I can't find any opening through the front to back roof beam. I'm hoping there is someone out there who has done this and can give advice. I'm stymied. Thanks in advance for any suggestions.

Consider going across the roof externally then down the fridge vent if there is one on the roof. Otherwise it’s take down a ceiling panel and drill holes as needed. Use bushings or flex conduit to protect the cable where it goes through ribs and longerons.

You mentioned you could not find an opening in the fore and aft roof rib. If you have already removed or loosened the center interior panel (a real PIA) then you're halfway there. If you have an A/C unit the center panel may be cut in two pieces under the shroud.
While I was rehabbing the Tradewind I ran new coax to the front and rear boxes. I found the old twin lead. I was able to use that to fish the coax to the front box after drilling a hole in the rib and installing a nylon grommet. The rear was much harder due to the bedroom window and a horizontal rib.

Good Luck,
Tom
