Normally our reception is fine, but last Saturday morning happened to record 2 programmes starting at 10am - More 4 on a Humax HDR-FOX T2 and BBC1 on a Sony RDR-HXD1095. Both suffered bad pixellation and complete break-up with total loss of signal temporarily. I think it was all before 10.30am.We have an external aerial and diagnostics usually shows signal strength 60-70% with 100% quality on all channels. I was not around at the time to observe anything unusual or check any other channels, but no electrical equipment was running in our house at the time other than that we always use.

I am based at Perran Sands Holiday Park just to teh East of Perranporth and experience interrupted intermittent reception on some channels. My aerial appears directe dat the nearby Perranporth transmitter. Is this correct or should I point towards Caradon?

Can you advise the best aerial type for my location.

Many thanks

Alan Bramwell: It's very difficult to say with absolute certainty, my trepidation being brought about due to the fact that you are probably low down, what with being near sea level and your aerial possibly being just above the height of a caravan. You may also have other buildings and trees around you that might reduce your chances.

However, you should be aware that the transmitter at Perranporth is a Public Service one only. The Public Service Broadcaster ("PSB") multiplexes carry BBC, ITV1, ITV2, Channel 4, E4, More 4, Channel 5, HD services and a few others. Therefore, if your receiver has tuned in the Commercial ("COM") multiplexes you will have ITV3, Pick TV and Yesterday. Don't be surprised if they're poor because they are being picked up from a different transmitter.

For Perranporth your aerial should be vertical. If it is horizontal then that could be your problem.

It is also worth confirming that the receiver is tuned correctly. For Perranporth BBC One is on C46, ITV1 on C43 and HD services on C50. This information is usually given on the signal strength screen.

As for which other transmitter might be worthy of a shot, Redruth is perhaps the best at 11 miles, although the fact that you are low down will reduce your chances. Redruth is a full Freeview transmitter, albeit that the COMs are at lower power than the PSBs.

The existance of the Perranporth transmitter suggests that the area may have difficulties in picking up from Redruth. It is a relay of Redruth rather than Caradon Hill.

Caradon Hill at 33 miles is predicted as being almost as good as Redruth. It is in a different direction and if you have a clearer view in that direction then that may be better than Redruth. Again, Caradon's COMs are lower power than its PSBs. The power of all its transmitters are greater than that of the closer Redruth's.

For Redruth or Caradon you need your aerial horizontal. If your aerial is a wideband one, then you will be OK (albeit that widebands are less sensitive to lower frequencies as used by Caradon). If your aerial is a Group B one then you will only be able to use it on Redruth and not Caradon. This is because Redruth uses Group B channels, just as Perranporth does.
