I am posting this in the National RV forum but it may be common to all class A's. I took this photo in the fall of a box on my roof, near the front, and never got around to posting it. Can someone tell me what this box is for? I googled the name CANTEX on the box. It seems they just make the box. No clue whats in it. Can anyone enlighten me.

As alway, Thank you.

Possible pre-wire for sat. ant.

That is a water proof electrical junction box. It would definitely not be a factory install. So it's purpose could be as already mentioned a sat. connection, or possibly it was wired for solar and this could be what is referred to as the combiner box. It will not harm anything to remove the top 4 screws to have a look.

It is for a fact Sat. pre wire connections. I removed the box on my motorhome and used the lid from it to cover the hole up.

It is factory installed. Contains 2 sat. cables a 12 volt power lead plus ground and a telephone type cable terminated in a standard telephone jack. Wires are all routed to the entertainment center overhead cabinets.

Thanks so much. I knew you guys would have the answer. I think I'll just leave it alone. No need for satellite.

That's what I thought, before I added sat. Wouldn't be without it now.

Everybody above is correct. It was installed at the factory to provide coax and 12 volts to a future sat antenna.
That said, don't ignore it just because you don't use it yet. If you remove the lid you will discover there is a hole in the roof and a chunk of the foam filler gouged out to expose, sort of, the end of a piece of conduit that runs forward above the TV. The future sat coax, 12 volt feed and the coax to your crank up antenna are all in it.
Like everything else on the roof it is a leak waiting to happen, so keep it sealed along with everything else.
When I junked my King Dome and crank up antennas, and installed a Winegard Trav'ler and a Jack OTA antenna I scrapped the box and did something I think works better.
