Had new fitted couple of years back, cos the aerial was 40 years old and terminal had suffered from water damage over the years. The new aerila worked fine, though signal /strength were poor on ch4, uktv history and others. No problems until a few days prior to Royal wedding, picture/sound breakup started first on Ch4, then even to BBC1/2. Completely spurious.Mercifully behaved ok during the wedding. Then few days ago, improved markedly on BBC1/2. Ch4 and Yesterday are still very problemattic. Signal strength/quality is all over the place, swinging wildly from to good! Any suggestoions anyone? When the aerial was upgraded, it was not set up using any meters! The installer pointed it in the right direction! Any suggestions please someone.

Bob-ji - Are others in the area having same problem? If so, probably weather, or adjustment of transmitters.

If just you, has moved? Should point due south I think.

If you have multiple TVs try connecting one at a time.

Bob-ji - I know that from clicking on the links next to your name - which are worth a visit if you have not. As is this.

UK digital TV reception predictor

A Field strength of 52 dBV/m is not super strong, but should be fine.

You do have a rooftop ? Is it looking through trees? (LL145HD)

Thanks Steve, I do have a rooftop , it does look thru a large oak tree, located about 80 feet away. However, it has been doing so for 40 years and no problems. The recent problem did appear when the tree grew foliage, so I guess that was the straw that broke the camels back, but something else must have caused a degradation too. The aerial has not moved as far as I can tell.

I have a PVR-9200T and all my ITV are not being received on my TV. 32 has very poor or no and won't pick up these channels when I re- my PVR. Is anyone else in this area having problems? Any suggestions?
