Andrew: my TV reception has failed and went down last night, 27th. Oct. I view through a Humax Video Recorder. On selecting a given station, the TV Screen brings up detail of the programme I should be watching but then details "No or bad signal". Any ideas on what has gone wrong?

K.M.Riley: You havn't included a postcode, but I'd guess that if you have a roof top aerial, then last nights storm might well have loosened or broken the cable from the aerial. Try following the connection back from the Humax through to the aerial. If its on the roof, you might well need a professional, who might be pretty busy for the next week!

Gareth Rhys: Your postcode is a bit difficult to pin down for a terrain plot, but a generic one does bring up a decent signal on the tradeview (even though Mendip is 64km away), which is supported by the fact that your on a hill, and that your signal was improved by the removal of your booster.
4G is unlikely, since you have no booster (ok - the aerial does boost, but still...), and you seem to get a pretty good signal. Personally, I suspect that most '4G' problems are actually something else anyway.
You've good good cabling, good connectors, etc, and Panasonic/Sony have good sensitive tuners. Its true that three TV's might lead to a drop in signal strength to each one, but I suspect the problem is more than that.
However, there is one thing that immediately stands out - ' The signal strength is middle and drops occasionally, with a concurrent drop in quality. It is poorer still with windy/wet weather.'
'Poorer still with windy/wet weather' - it sounds like you have a problem with the connection between the aerial and the tv, and its very possible that its the result of a loose connection, corroded or waterlogged coax, etc.Since its all three TV's, its above the splitter.
You might need a pro to examine the parts on the roof, but at least study the cabling you can see.
Let us know what happens, and if you can put you full postcode on any future comment, we can see the exact terrain plot.

Re Gareth, you sound from the postcode like you're round the corner from my parents, who have generally had better Freeview reception from Mendip than I do here in Bristol, so for Mike B I'd tend to trust the generic signal forecast. Unfortunately my phone's just gone down, so I can't ask them if they've had Freeview issues recently. I note that they didn't seem to have much storm impact this week, but all the rain could have got into cabling.

Does anybody have any idea when I will be able to get the rest of the freeview HD channels in Chippenham. I've only got 2 extra so far, BBC 3 HD and CBBC HD. Really looking forward to BBC 4 HD.
