Where are people putting the 1.35m+ dishes needed to receive Astra 2D signals in fringe areas? On the roof? On the balcony? In the garden?

My local installer (very sensibly probably) recommends that anything over 1.35m should remain firmly on the ground.

What does anyone else recommend?

I'm looking at a 1.8m dish for my location (Madrid) that would either have to be attached to the chimmney or the roof ridge as there isn't room for it in the garden.

Thanks.

Can you provide any photos of the potential locations Andrew? A 1.8 metre dish requires a pretty substantial mount.

A little less analogue, and a lot more crap.

Its all dependent on the building, its structure, surrounding obstacles and the prevailing climate

Ive used wall mounts that have post diameters up to 4 inches, which will accomodate a 1.8m dish from Prodelin, but the bolts that are recommended are of the chemical variety.

Rolf,

I don't have a digital camera to hand, but my preferred mounting location is an approx. 60cm x 60cm chimmney (where I already have a 1.35m offset dish that no longer does the business). So far, the 1.35m dish mounting has proven to be secure.

My question is really whether people are putting 1.8m+ dishes on the roof/chimmney etc. or is it simply not sensible.

By the way, Channel Hopper, what are 'chemical variety' bolts?

Thanks.

There is no way that I would advise mounting the 1.8 metre dish on a 60cm by 60cm chimney Andrew, the wind stress would be tremendous. There are through roof mounting systems available, but they need to penetrate the roof to attach to the joists.

I have known people, where the dish direction matches the roof slope, to mount an offset dish upside down, that way it mirrors the pitch of the roof and causes less wind resistance, it is also slightly less visible.


PS. Chemical bolts are large studs contained in an epoxy case, they are placed in the hole and then the epoxy resin is mixed by either hammering (thus breaking the separate containers or a hardener being inserted. They have amazing strength and grip, even in soft materials.
