We live by Troon Marina, so just outwith the published coverage area of the Troon relay transmitter. Freeview reception is normally fine, however, but, over the past few days of wild weather, pixelation has been very severe in the evening only - no problem at all during the day! The aerial's in the loft of a small block of flats with a distribution amplifier and internal cabling, so direct weather impact seems unlikely. All flats are similarly affected. Is a wet roof in a marginal signal area a sufficient explanation? Thanks!

David F: I'm not an aerial installer or expert in the field of how TV signals propagate or what affects them.

I do, however, wonder if another issue you might have is that because the transmitter is directional to its north-east side (see radiation pattern near the top of this page), it could be that your aerial is picking up reflections from the main service area (i.e. from where the main beam is focused) in addition to the bit of signal that radiates in the 'wrong' direction.

Can you not receive from Darvel (you might need a roof-top aerial)?

Thanks, Dave - sounds like a feasible suggestion, although I'm certainly not an expert either! The signal strength isn't bad, but the 'quality' (error rate) is poor, which may point to interference. Unfortunately, Dundonald Hill prevents us receiving a direct signal from the Darvel transmitter, at least with the loft aerial, and a roof aerial is prohibited by our Deed of Conditions. We do, however, have a communal satellite dish installed in the block, so we've bitten the bullet and bought a FreeSat box!

David F: If it is reflected signal (and it is probably difficult to say without professional test gear), then it might be possible to re-site the aerial so that there is something blocking the reflection. For example, move it to where there is a building in the direction you think that the reflection is coming from. Turning it might help. I guess that it should be turned anti-clockwise, although there is no harm in trying clockwise as it might pick up some perminant reflected signal which could be more stable.

What about using the West Kilbride relay? If your aerial is a group one, then you will probably need a replace it with either a group B or wideband.
