Hi Folks,
I'm planning to move my in-the-loft telly aerial outside of the loft
and
the present thought is to attach the aerial to the side of a dormer
window.
The dormer is nothing special, but I am not sure which bits of metal
I'll
need to do the attaching. Screwfix shows various "cranks" (page 278 of
autumn 2005 catalogue 79), but since I've
never done this before it's time to engage the good advice of the folks
here.

I guess I'll need the "wall fixing kit" (but it will be attached to the
wooden side of the dormer) but beyond that would one of the offset
cranks
be enough to keep the aerial proud of the dormer?

Advice requested; thanks in advance.

My advice is don't bother. I suspect that a better aerial in the loft
will make far more difference than moving the existing aerial outside.

I moved my loft aerial outside a few months ago and the improvement is
negligable, I've gone from fairly good digital reception with the
occasional droput to fairly good digital reception with the occasional
droput. I also couldn't see much difference in the signal level
indicated by the STB's signal strength display.

The aerial is now a couple of feet higher than it was when inside and
the downlead is no longer. I think rooves attenuate the signal less
than the 'rules' suggest, maybe it depends on the roof a bit, ours is
just an ordinary tiled roof.

The one thing that improved was the ease of setting up as I didn't
have to position the aerial quite so carefully when it was outside,
not from the direction point of view, when it was in the loft there
were some 'holes' due to reflections/standing waves.
