Running cable thru roof

I am looking at adding a WiFi amplifier and antenna. I am thinking iof running the cable up thru a kitchen cabinet and thru the roof. The supplier suggests drilling a hole thru the roof and drilling the same size hole thru the bottom of a non metallic waterproof electrical box (probably a 4x4 box). They make a watertight connector that I can go out the side of the box and attach the antenna to the batwing. They suggest putting some type of caulking or sealer on the bottom of the 4x4 and attaching it to the roof with wood screws. Do you think this would work and what type of caulk sealer would you put on the bottom of the box to seal out moisture?

I would use Dicor sealant, it's very good

No matter who puts holes in your roof, whether it's installing a satellite dish or solar the professionals use Dicor self leveling sealant.

Had the same setup on op of my diesel pusher that I used to have. It never leaked a drop in the eight years we had it. John

Just a suggestion. Locate the vent for the galley tank. If it is convenient for where you want to run the coax, drill a hole in the vent pipe under the kitchen counter and run the coax to the roof thru the vent. Then just seal the hole (under the sink) with your choice of sealer. There is only air in the pipe.

The roof vent cap just pulls off and the coax will exit the cap with out any mods to the cap.

Jim

Actually Jim you don't have to run the cable into the vent pipe. Here is a picture of how all my satellite cables were brought into the RV beside the Galley vent. You can see the way the vent is configured on the roof and it is just a matter of drilling holes in the vent roof fitting to bring them in. Dicor was used to seal the holes where the cables came in.
In some cases it might be better to do the same thing from the bathroom vent depending on the layout of the unit, they should be the same in both locations, at least they are on mine.
The galley vent was chosen on mine because it was the shortest run of cables from the Satellite dish to the vent the cables were attached to the roof with Dicor.

Never had a problem with it in 3 years.
