Leak at TV aerial - what's the best solution?

We have a leak at the TV aerial on our newly bought camper. We want to remove the aerial and cap the hole. Is there a strightforward method for this?

This is a pic of the interior. There's water coming down the screw thread, and also water above the flange and below the ceiling.

Here are two pictures of the exterior:

That looks like ordinary silicon around the base.
Looks to me like someone has attempted to fix the leak before.

The caps only fill the hole the ariel ccaoms out of so if you leak is under the base it will not help.

As Ally says, buy sikaflex, remove the whole base and clean all the silicon off it. Put it back on with a real good layer of sikaflex to bed the base into. Make sure it is thick enough to allow for the ridges on the tread plate.

That would allow you to keep the ariel.

You should be able to get sikaflex at any good hardware store---check the use by date

Give Peter a ring at Donagheys 0749111111 and he can post you some, don't know the price sorry

Around that joining of the two checkered plates is a bad place and I would remove the plate and work the sikaflex around the hole for the ariel.Put the plates back and put the sikaflex where you see the domestic mastic in the picture.All around the edges of the plate should be done as well ,just to be sure.Hope this helps .

Mr Cool is correct, But if the checkered plate is Bonded on to the roof skin, I would not attempt to remove it as the checkered plate is thicker than the roofskin and you might damage or even tear the roofskin. if you can prise the roofskin slightly apart from the checkered plate around the circcumference of the hole, dry it and put sealer in, it should do the trick.

Here you go.

The problem manifest itself as persistent drips coming down the inside of the ariel shaft.



Like you I initially assumed that the problem was with the roof mount. But as there was no signs of dampness on the ceiling I began to doubt that. So I decided to open the up the unit itself to have a look. Initially you could be forgiven for thinking that it is a sealed unit but it isn't.



And voila:
Here was the problem.



Resealed it with silaflex and not a bother since.


Hope that helps.
