And just as suddenly, it all returns; no reason, system is only two years old and aerial not moved. :(

john garratt: Although the signal may well have returned, purely out of curiosity I was wondering that if whilst no signal was being received from the Redruth transmitter whether or not you managed to verify that this situation was also being experienced by any others located in households in your immediate vicinity? if not, then what is the strength and "quality" (the most important by far) of the signal being presently received?, as the levels indicated might give a clue as to why your reception dropped out in the first place.

The aforementioned said on the basis that no faults have been reported against the Redruth transmitter, nor have I seen anyone else complain about reception from this station.

I am looking for an outdoor aerial for our bungalow at St Merryn Cornwall, PL28 to replace a damaged tv aerial. Do I need anything specific. I sometimes get a pixelated signal and problems with BBC reception. I have tried a good quality indoor digital aerial but with unsatisfactory results.

Regards

Scott Glave:I would recommend you having a good quality log periodic aerial installed. That will cover all current and future (as far as can be determined for now) channels. Remember that there is no such thing as a 'digital aerial' as all UHF aerials can receive both analogue and digitally encoded signals equally well (it's just an excuse to charge more, I think).Indoor aerials never give a good experience, not even in the old analogue days. Digital signals can be more difficult with indoor aerials, so I'd advise going for a replacement outdoor aerial as suggested above.

Scott Glave: I echo MikeP's suggestion of a log periodic.

Also, I think that in St Merryn Caradon Hill will be the usual choice, unless there is some obstruction (eg building or tree) precluding this option.

There's apparent line-of-sight to Caradon Hill:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


Whereas to Redruth there are obstructions up to about 4 miles out:
