Magnetic TV roof aerials

I would think the thickness of the roof would reduce the magnetic force to an inside plate to a point where it would be ineffective. However, the only way to find out is to try, although presumably it would mean sticking any plate to the inside of the roof. Surely the metal cab is the best place, you have the option of putting your MH face in or rear in to optimise the signal. Direction can be established using an app, or by observing the direction of the site, or local roof aerials.

Is it an Omnimax aerial? If so, you can get suction mounts instead of magnetic. Link

I very much doubt a magnet would work through the layers of material used to construct your roof. Perhaps attaching a metal plate to the outside of the roof would do the job or, alternatively, try an aerial which attaches by means of a suction cup.

Maybe you should cut your losses and save your sanity and buy one of these https://www.avtex.co.uk/antenna/sth3000 It has a sucker attachment which is pretty strong and pulls in a good system. If you have an Avtex TV it takes its power feed direct from the TV. If a none Avtex TV is used it has a separate power cable. We used one for several years on our previous motorhome.

Omnimax make? a pole that can be attached to the body of the LV

Another vote for the Avtex. It has yet to let us down and just suckers to a [clean] window or your choice.

Why not stick on your living space roof, with suitable glue, an iron or steel plate that will take the magnetic mount of your aerial?

Been on the look out for a good replacement aerial. Can you tell me if this is a proper directional aerial? Also, can it be switched to vertical and horizontal polarity according to the local transmitted signal? Or is it just a simple amplified omni, David?  

You do not alter the rotation for vertical or horizontal, to pick up on main transmitters or boosters. All I have done is looked at https://ukfree.tv/maps/freeview and made a note in which direction the best transmitter is. I sucker the aerial to the window but you must clean the window first or it will fall off. Plug aerial into tv and press tune. It really is as simple as that.

When teamed with an Avtex TV it sends power to a built in amp in the unit. If you have an Avtex TV then a secondary in line lead is provided for the power feed

The rod the aerial is on is flexible so you can twist it into any configuration. We mainly stuck it on the side of the van, see picture below.
