Hi folks,
I am currently served by Kerry here in darkest mid wales, and it's group
A at the moment. 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,
and will have a MythTV server in the Garage, which is why I am putting a
stig on the garage.

Rob.

Yes but are'nt we all switching to a common frequency post 2012? Have I
understood that correctly?

No. Digital switch over will not result in the whole country being on
the same frequency. Digital switchover for the whole of the UK is set
to be complete by 2012.

Digital switch over for Long Mountain and it's relays (one of which is
Kerry) will take place in the first quarter of 2010. DSO will take the
pattern of the BBC2 analogue being switched to the BBC A mux and then
one month or so later the other analogue channels being switched off
and replaced by the other muxes.

Hi,
Is that a 'Barbecue' aerial?

Before today, I had not heard that description.

Are you referring to a bow-tie array?

I have Preseli here, just copied this from that PDF

A log periodic would seem to be the obvious solution, but I hope the OP is
not too far away from the Tx. Being able to see it is no guarantee of good
signal strength, especially with such low powers.

Since mulitpath is not normally an issue with DTT and since the chances of
the small relays ever carrying additional muxes seems remote (and the
chances of them being out of band even more remote) I wonder if a good 18
element Group A might be a safer bet.

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+.
