Before today, I had not heard that description.

Are you referring to a bow-tie array?

I think so yes, the one with the flat structure..immune(?) to multipath
problems? Would have thought Bill had heard of that?

What? This Bill? I didn't know I was involved in a discussion about bow tie
arrays. Anyway, do you mean a grid aerial, commonly called a fireguard?
These have two or four dipoles in front of a large reflector. The dipoles
are one above the other when the polarisation is horizontical and are
connectified together by 'phasing bars' which cross to compensate for their
differing lengths.

Hi,
Sorry to drag you into this one Bill, but yes I think that's what you're
talking about. I shall follow the idea of an 18 element Group A though.
This was the choice I had made unless there some positive comments
about a WB aerial.

I will need at least an 6 way distro amp as I will have six tuner cards
in my server. I have been using MythTV with a Satellite feed from Astra
2. The EPG is a real challenge though and falls short of the Wife
Acceptance Factor. She has only just got used to VoIP, but I have some
way to go to get her to dump Sky+.

Should I get a wideband to cope with any eventuality
or should I actually get a group A? I can see the Mast from my
garden

If you are so close, why not consider a log periodic (which is wideband)?
