Electric Powered RV Mast

Has anyone attempted to make or sell an electric powered antenna for the roof of an RV? Is it even feasible?

I have seen the heavy duty powered telescoping antennas for military use, but they are huge and astronomically expensive. Telescoping is cool but perhaps more complicated than a tilting / actuating mechanism of some kind. I have seen some cheap linear and rotary actuators that may serve the purpose with the right hardware, but nothing that is specific to the application of automatically raising and lowering an antenna pole.

I am trying to find the best solution to mount my 40" antenna, with these main considerations:

1. Cost
2. Modification / holes in roof
3. Equipment
4. Ease of setup / use
5. Reliability

I know there are many threads on this subject, most of which I have already read and seen other user's solutions. I am wondering if there is anything specific to unconventional setups, like a powered mast?

Maybe an automobile junkyard and find one of those telescoping antennas that operate when power is applied. They may not extend 40" but up on the trailer roof they are taller than on a car. Just seal the hole very good.

That would be cool for radio signals. I was thinking for larger high-gain antennas, some that are an inch or more in diameter and several feet long.

Have you considered something simple and manual, that mounts to your bumper or tongue? On it you could mount various antennae, for TV, radio, phone, wifi, etc. This though is on my mind for a rear mount, with an access panel on the back of the trailer in which connections are made.

No flags here, my trailer is not a government building.

Though, I have considered getting a nice Canadian flag decal for my trailer. Something to supplement the tire cover, and small "Made in British Columbia" maple leaf.

Ham setups I have seen generally use the rear bumper to anchor a tall antenna - some more than 10 ft above the top of the roof. One guy had telescopic tubing set up with a gearbox/crank that made it raise. I would NOT punch a hole in the roof for anything that could get snagged by tree limbs!

Here's a place to start: Mast Systems - BlueSky Mast

I was just looking around, and saw a couple nifty ideas, I am sure some of you already knew about. One was for a base. A bunch of people us one that they park the tires on to give it stability. A good alternative to something mounted on the trailer frame. You could also put it under your stabilizer.



Fibreglass extendible masts.

We were at a place in the Yukon that was hosting a ham radio event. Some of their telescoping rigs were truly awe inspiring.

I'd search for ham radio telescoping antenna mast and see if anything they use would do the job for you.

Gotta agree with others, a mount of the rear bumper or the spare tire holder would be my first choice over a hole in the roof.

Leon has a nice simple plastic PVC water pipe one for his wifi antenna, carries it on his bumper. ( I just texted him to post here, but he's out with his beer pub group having more fun than posting here right now)
