Several years ago I installed a Sony Marine AM/FM/CD radio in one of my lower compartment boxes.



It's worked rather well but it was always a pain to hook up the antenna. I would hook an external cable to a marine antenna and mount it to my awning. I knew that one day, I would eventually hook it up the right way.

When I was running the wiring for the Inverter, I decided to run the antenna cable into the same closet with the generator/inverter selector switch (other side of coach) and up into the roof.



To do this I removed an access panel and removed a section of the ceiling material. Because it was inside a closet, I decided to go bigger with the hole, rather than smaller.

Here is a cross section of what the material looks like in my coach.



You first have a layer of vinyl, followed by 1/2 green foam, then it's a 1/4 piece of plywood, still another piece of vinyl and 2 pieces of aluminum foil sandwiched above and below what looks like 2 pieces of bubble wrap glued together.



My coach has a vinyl ceiling, most of our coaches have a felt ceiling. Because my coach was a former mobile medical lab, I'm sure they chose this type of material for cleanup ease.

I now have a working radio without the need to run an external antenna cable anymore.

I know that this is a rather low tech install and I wouldn't have posted it... But, one of the things I wanted to show you was the ceiling material inside my coach.

Mine also has a vinyl headliner - handy when my pet gecko comes in with muddy feet.

Mine is also vinyl, Bill, looks like your insulation is about the same as mine! Hardly what I would call good.

Also I have water damage to the foam between the vinyl liner and the wooded backing, in that area, it is hard as a rock, a year ago I accidentally bumped that area and the vinyl split, haven't addressed that yet.
