Up till now I had good FV OTA reception. But in the past week, with no changes on my part it's gone terrible with pixellation, dropped audio etc. It can be watchable on TVNZ but on TV3 (and TV3+1) it can be quite terrible with pixellation (severe), flashes of video from seconds ago, audio dropouts etc.

Mindful of that the fact I live in Wellington and its attendant high winds, I am guessing that possibly the external UHF antenna might have got blown out of alignment? I can't think of any other reason and I have made no changes inside the house.

Thoughts on this?

I'd start by checking the connection between your aerial cable and the aerial. If it's not an F style connector then any oxidation there may have dropped you below the signal threshold you need....

+1, start by checking / re-terminating the connections on either end.

Maybe I should have done that :-(

I had a guy in who went on the roof and found the signal strength was fine.

He then went to check the outlet and found a couple of things.

He could not insert his tester because a splitter I was using (and to be fair, had never moved) had its surround fitting broken and was therefore causing a faulty connection. He also found some strange installation where the cable from the roof was joined to another cable and fed presumably to another room. He said (and I agree) that multi-room connections should be taken from the main cable from the aerial with an appropriately shielded and wired splitter box.

After replacing the wall socket, the picture was fine.

Oh well, $100 well spent I guess!
