Ham Radio project and near disaster!!

Whew! Really dodged a bullet there.

The floor in my Rockwood is a sandwich made of plywood with styrofoam in the middle. Easy enough to drill through with a 2" hole saw, right?

Styrofoam isn't the only thing in the sandwich. While drilling a 2" hole to install a feed through for antenna cables I discoverd, to my horror, there are two aluminium box channels that are just chock full of wiring imbedded in the floor material -- not under the floor, I looked, but inside the floor, a few inches in from the exterior wall.



The good news is that none of the wires were damaged, and the hole is located in a cabinet so there's not really an eyesore problem. I drilled a few "exploratory" holes a few inches over and got a good hole (nothing but styrofoam there) for my feed through.

When I get done I'll post pictures...this weekend.

Dodged the bullet is right! Had you sawed through the wiring you'd have a major job on your hands. Glad you found it before that happened.

My unit has the sandwiched floor like that but I never thought about wire ducts being embedded in it. Thanks for the info. I'll know to be very careful if I ever find the need to penetrate the floor.

I wonder if FR would send a layout of the floor if you requested it? That'd be something good to have especially in this instance.

Yikes!!!
I drilled thru my floor in the front to hang my spare tire up there and get
it off my bumper.
I didn't hit anything but styrofoam but I could have!
Didn't you feel the hole saw hitting the hard stuff??

Anyway, glad it turned out OK. Sometimes the best luck is just dumb luck ;-))

A few pics of finished job

I won't devote much bandwidth to this as most folks on this forum are not "hams" but for those concerned about the outcome of the project and what I was up to, here you go...

The first pic is of the pass through tube uninstalled.

The next is of the tube installed inside the cabinet floor.

The next is of the exterior end of the tube under the floor.

And the last is of the radio station set up for use. The station disappears without a trace when not in use. The pass through tube will accomidate 6 - 10 cables of reasonable size and of any type - power, ground, coax, Cat-5, whatever you want.

And I'm all done with drilling holes in my new trailer. Now I'm going around filling in holes with duct tape and Great Stuff trying to help my air conditioner battle the Georgia Summer heat!

Looking at the placement of your "station", you might want to think of creating a little splash guard. One simple accident at the sink, a little splatter and you could have a real problem on your hands.

I have thought about that. The set up works about as well between the two chairs in front of the big window. Also thought about just tossing a "raincoat" over the radio when someones doing dishes.

Another reason to use paper plates??

Nice idea. That will be useful when I run my coax for my new rig. 73's

Nearly had a mishap in the basement of my 5th wheel. I was going to bolt some items to the floor without a thought of what might be beneath. Some phone calls confirmed the location of the holding tanks right under that styrofoam sandwich.

Had I used longer screws I would have "holed" the tank.

What are you running for antennas and grounding?

Are you too far from your batteries to run the 12V instead of the power supply?
Would not matter if full hookup campground, which we do very little of.
