I live in Warfield Avenue, Waterlooville, PO7 7JN. When I moved here 12 years ago, I was struck by the number of high aerials that there were in the area. Obviously we are in a shaddow of the downs on the northern edge of Portsmouth, but why wasn't a repeater station built on the downs? Is it to give more business to aerial erectors!?
My aerial is on the far end of my garage roof which is behind the house. It was put there, primarily, to reduce the interference from household appliances in next door, but it does have a clear 'view' with no property in the line of sight, which is parallel to the street.
However, my main question is to ask if there is a reason for occasional poor reception of the Yesterday Channel? I did think it was related to climate but I cannot discover a distinct correlation.

Waterlooville
Ever since there was a change of channels a couple of years ago, I have had problems with the Yesterday programme on Channel 25. It breaks up for a minute or so every five minutes or so, and, of course, the sound disappears. The problem is, definitely, a bit worse when the atmospheric pressure is high.This is a nuisance as this programme is one of my favourites. I have no problems with any other programmes. However, I did notice that all the channels on the same MUX, COM6, tended to break up, too.
Being technically inclined, i have tried fitting a second amplifier in the aerial lead but this did not make any difference. Also, i had the aerial bearing changed to make it, almost precisely,in a SW bearing which should be correct for Waterlooville (PO7 7JN).
One of my TV sets displays a signal strength reading for a couple if seconds after a channel appears and, by taking several readings, I noticed that the signal strength for Channel 25 was between a half and two thirds that of other channels and varied, considerably, whereas it was quite steady on the other channels.
On the polar diagram towards the end of this page on your web site, COM6 is supposed to be shown in yellow. But I cannot see the yellow line on the polar diagram. Which one is it or is it coincident with the brown one?
If you have any ideas as to how this problem can be solved, I would be pleased to hear from you.
Incidentally, when I moved here from South Devon ten years ago, I was very surprised to find that there were not a repeater stations on the Downs Ridge as this ridge is an obvious barrier to the signal for those on the immediate north side of it. However it does explain why it seems necessary to install a complex aerial on a long pole on, virtually, every house in the area. A lucrative business for aerial erectors!
