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 TV 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 5G-at-800 interference) as well as tabulated information (sorted by direction, by received signal strength, by frequency, by service names or by transmitter name).

Please note

These predictions are based upon a rooftop aerial and depend on the suitability of the aerial, the distance to the transmitters, the power of their signals, the postcode area, and local terrain.

Dave Curle: If you click on "Digital UK tradeview" on the right hand side of your posting this will indicate your reception possibilities for the P/code supplied, which from the Aviemore station is only BBC / ITV / HD services.

However you might manage to pick up the commercial channels from the full service Knockmore transmitter (@ 35 miles / 49 degrees) albeit that two of its commercial channels (Arq A /Arq B) are not shown as being possible to receive, and with the SDN mux (ITV3 etc) being indicated as poor.

Its really a case of pot luck as to whether or not you would be able to receive these commercial channels as variables always exist with any prediction due to the nature of RF signal propagation, i.e: nothing is exact once the signal leaves the mast.

By the way the signal path from the Knockmore transmitter is obstructed in three separate places as indicated on the link, starting at 35mls / 16-17mls / finally at 12mls prior to your location.

Dave Curle: In addition to the points made jb38, it may be worth pointing out that the three COM channels from Knockmore are co-channel with the PSBs of Angus, so you "might" find that you can receive all channels from Knockmore, but that during particular conditions the Angus signals degrade your reception.

Hi I have 3 TVs using 1 rooftop aerial pointed at Sutton Coldfield. 1 of the TVs has always had intermittent breakup and weak signal warnings on BBC channels (mornings and evenings). From your excellent website and the tv's manual tuning feature, I've managed to work out that, after an auto-tune, it should be using channels 39 to 46. It actually displays 23, 39, 42, 43 & 45. I am able to manually replace 23 to 46, but Is there a way that I can stop it using 23 whenever an auto-tune becomes necessary? And, as all channels in use are 100% signal strength (60% on Ch23), why would I be having trouble with the BBC channels which, I believe, are on Ch43?

Peter Wickenden: Once a receiver has performed a scan it must "decide" which signals to go with. For whatever reason this TV chooses another transmitter.

I'm puzzled because C23 is used The Wrekin, Bromsgrove and Lark Stone for PSB2 (ITV, Channel 4 etc) and the nearest PSB1/BBCA transmitter on C23 looks too far away. See:

C23 (490.0MHz) after switchover | - 10 years of independent, free digital TV advice

There is an easy answer and you may kick yourself. The scan runs from channel 21 to 69. Therefore have the aerial unplugged for the first 30% of the scan so as to miss out C23.
