By providing a full postcode (such as W1A 1AA), national grid reference (for example SE123456) or latitude, longitude pair (like 54, -0.5) this page will provide a map, terrain plot and detailed information of the location showing the UK and RoI television transmitters that it is possible you receive Freeview, Freeview HD, Youview, BT Vision and Saorview from.

(Don't know your postcode? Find it at Post Office Postcode finder).

UK Free TV uniquely shows you transmitter coverage maps, aerial to transmitter terrain plots, the closest 10 mobile phone masts (for possible 4G-at-800 interference) as well as tabulated information (sorted by direction, by received signal strength, by frequency, by service names or by transmitter name).

MikeP: I gave it another go last night with the original lead. I did several manual scans of the multiplex channels and had some success in picking up a few of them (about half). The TV seems to pick up channels and get signal for viewing when the aerial lead is held and positioned in specific places, then when I move the lead even slightly the signal is lost. Does this sound to you like an issue with the lead or the aerial sockets?

Why would the signal be working perfectly then suddenly I have to hold the lead at an angle?

I noticed that I have a separate aerial socket in a different room so I will give that one a go to see if it works. I will also purchase a new aerial lead.

The short aerial lead from the back of the TV to the wall socket can work as a poor quality aerial and that is why you get a few channels unreliably. Replace the flylead, as MikeB suggest, and if you still have the problem then report the fault to the managers of the blockj as they are responsible for the communal aerial system. Also worth checking with your immediate neighbours in the block to see if they have a problem. If they do then it is a general aerial system fault, if they don't then it is likely a fault with the feed to your apartment. (It is not unknown for some silly people to cut aerial leads on a whim, I suspect they think it's fun!)

Let us know how using the socket in another room works. That could have a separate feed from the main aerial system compared to the one you generally use.

MikeP: the aerial socket in the other room was very marginally better but I still had to move the lead around to get signal, then when I dropped the lead the signal would go.

The new aerial lead that I bought couldn't get any signal at all in either room.

I managed to pick up a few more channels (itv, ch5 etc), although these were then numbered in the 800s rather than the usual 3 4 5 etc. Apparently this is because I'm picking up signal from more than one transmitter, perhaps this is why the signal is bad? I am manually retuning according to digital UK's instructions for the Crystal Palace transmitter.

Any ideas!?

That proves that there is a fault in the aerial system, especially the part that feeds you apartment. Contact the owner/management who are responsible for maintenance of the block to have the fault corrected.

Your new aerial flylead is clearly better screened than the 'old' one so it will be less likely to pick up signals accidentally. (The flylead should not act as an aerial at all.)

Did you speak to your neighbours? Are they having the same problem?

Hi, I get a Signal Strength of around 64% with a Signal Quality of 100% on my Freeview Channels in Otley, West Yorkshire via the Wharfedale Transmitter using an LG TV. Is a Signal Strength of around 64% OK? I don't get any issues with the picture at all? Many Thanks for your time, Andrew

Andrew Land: 75 % is supposed to be perfect - but if your getting a good picture with 100% Quality, then thats fine.

If you put your postcode into this site, it will bring up a load of links, which should tell you what channels and signal strength you should get. If they make sense, then dont worry about it.

Andrew Lands:

Further to that said by MikeB, it is typically acceptable to have a signal strength of between 50% and 85% for SD services and between 60% and 85% for HD services to get good reception. If the signal strengfth were lower or higher than these figures then you would experience some problems with pictures breaking up or some loss of sound.

Your stated signal strength at 64% is well withing the acceptable range, so no worries on that score.
