Take a look at the TLC aerials, they have one high gain version, just
make sure you buy the correct band .... check the IBA site to find
out what your transmitter is - and whether you need to set for
horizontal or vertical polarisation.

whoosh ok you lost me :-}

That means whether it stands up or lies flat, and where it points.

Hint - check the neighbours.

Also if you're buying from a reasonable dealer, he'll be able to tell you.

There are web sites that will, or you could ring bbc information
information, but I've got a suspicion thats gone down the tubes like the
rest of the Beeb.

I can't find a site, but this being the ng that it is, I very much doubt if
we'll wallow in ignorant bliss for long.
