Chimney aerial corner plates position

I would normally want to spread the load across two courses. However cheap corner plates can collapse into the mortar if it is slightly or very recessed.

The whole idea of the corner plate is to distribute the pressure, so in theory, if the chimney stack is sound then its fine. I've never seen lashing end up so tidy when you tighten it up in any case. Chimneys, it seems are not precision engineered to be very symmetrical or even.

The galvanised ones on the mast I used to have were still sound after 25 years, I'm assuming crap plates are not used! Brian

Too late now. The plates I have are from Screwfix (Labgear chimney kit) so I guess of the cheaper variety. The kit is too small anyway so I only used the corner plates.

I've had my chimney stack (bungalow) reduced in height because of the number of spalling bricks higher up. The roofers lost the original heavy duty plates and needing TV on in a hurry I ended up at the local shed.

It had previously been suggested the stack be lowered and I've resisted because I'm sitting in a bit of a hole but Waltham still gives the best reception. I've got a Log36 on the end of a 3m/10ft pole but now have lost about 2' or more in height. We lost reception last night and I don't know whether that was atmosphere, obstruction or something I've disturbed. It's ok today (so far).

I have this job to do this year or perhaps next. I am somewhat tempted to give up the terrestrial aeriel and get a Freesat dish, which can also go somewhere a bit more accessible.

I was going to make the same suggestion. My dish is five foot above ground level. In dodgier locations a bit higher might be better - to keep it from being nicked/vandalised.

Amazing how some neighbours have been conned into putting up lofty dish-topped masts. Fools and their money ...

Something in the way of the signal?

Nope. Some aerial installer made a good sales pitch, I guess. He's also made a packet out of huge yagis. We get by with a mid-size Group A loft yagi - even after some of the multiplexes shifted up.

Still, they, no doubt, were sold "digital" aerials !

Do you really mean that the dishes are on tall masts for no reason? It's a very awkward install if you can't reach the dish, though it can be done.

Bill

No obvious technical reason that I can see. Perhaps the installers are still following the old "high in the sky" theory that I remember from my days with Telefusion !

How do you do it? I really need a taller mast to get over some trees.
