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.

Sam: Its working now. can i ask does the HDMI Resolution have anything to do with this as my grandad has a new tv and was wondering if he could have easily changed it by accident

Sam: No, the resolution cannot change - either your box is picking up HD channels, or its not. Assuming you had HD channels (BBC1 HD, etc) which then didn't appear, and then came back, start with your system. HD channels tend to vanish first with a dodgy signal, so if your aerial connection, etc was acting up, then that might explain it. Is the box acting up? And could I ask if you are using HDMI, scart or both to connect the box? You should only every use one lead, and if your using scart, then you wont 'see' any HD channels. Use only HDMI.

If its coming and going, check signal strength (too high can be bad as well), to work out what the problem is.

I have recently, within the last two weeks, lost all of my HD channels. Seemingly all on the BBC/B multiplex.
I'm at DE21 2HE post code.
Have a loft aerial and my configuration has not changed in any way.
All was working perfectly before this loss.
Any ideas on how to get the channels back?

My postcode is S44 5BS, I have been having problems in the evening watching channel 4 and itv and other itv and 4 channels where I cannot watch them at all. They go all pixelated and then nothing on screen yet Tuesday and before that everything was fine. Why would this happen? I would be grateful of any ideas thanks.

Thanks for getting back to me Mike. I can confirm that there are significant trees in the vicinity of our house, but I really would not have thought their density or height would be such that they adversely affected the quality of our reception. We have one small (almond) tree in our front garden which does not extend to any where near the height of our aerial, some distance (50 yards approx.) from our house are a number of large trees, which from my layman's geography would be in the general direction of Winter Hill. Obviously, I know that trees do grow, but we never experienced any reception problems in the days of analogue TV.

Sorry about my post-code not appearing (WA9 5UH); I can't see where on the web-site it requests this.

As for the 4G issue; from my research, I understand that I should have received a post-card from At800, advising me that the switch-on of 4G could affect my TV reception; as I did not receive any such postcard and as the publicity of At800's services has been non-existent, I knew nothing about the potential 4G problem. I only found out about the 4G hiatus when I personally contacted an aerial installer who remedied the problem by installing a filtering device. having been alerted to the problem, I then did my research and it was only then I found out about the existence of At800.

I would have preferred to stay with Freeview, but I am disappointed and feel 'let down' after the hundreds of 's I have now spent on attempting to at least restore normality; sadly, the problems persist with a few TV channels. This is why I feel compelled to explore the possibility of Virgin. Again, as a layman, I know nothing about the speed of my broadband connection; however, I can confirm that I did watch a 2 hour long film off YouTube last Saturday and only experienced buffering (for approx. 3 seconds) on one occasion. In any event, I like to think that Virgin would advise me as to all the options/what best suited et.c.

Keith: you have a choice to make if you want to solve your freeview problem, either plague the person to come back and make sure you have proper reception, the thing is he does sound like he doesn't know what he's doing. Second choice is get someone new in to sort it out, the only problem with this is if they are like me I won't use other people's equipment so would scrap everything as I tell my customers is I only warranty my own equipment.

The proximity of trees only some 50 yards away does suggest that reception can be affected by them. My house has trees some 50 yards away and if I try to use the original aerial that 'looks through' those trees I get poor SD reception and no HD reception. So I use an aerial mounted the other side of the house making it further away from the trees and doesn't 'look through' them but rather looks to one side of them. Now I get excellent HD as well as SD reception.

Such problems existed in the analogue TV days (I was a senior Field Service Engineer in those days so met such problems fairly often) but the effect on reception was less dramatic than it is with digital.

I'd suggest getting a good aerial contractor to have a look at your aerial system and consider moving it to a place where it does not 'look through' your nearby trees.

I live in Newtownabbey BT37. My freeview signal is breaking up on a lot of the channels. Does anyone know if a plug in aerial booster would improve this.

many thanks

You are only 10 km from the Divis transmitter and just 2 km from the Carmoney Hill one, so both are rather close. You also have several mobile phone transmitters nearby, thought the map at Freeview reception at BT37 0HU does show you are outside of the service areas a little. I would suggest you check the signal strength readings shown by your TV set (look in the User Manual for your TV to find out how to show those but *do not* perform a retune). You should also check which channels are tuned in to find out which transmitter is being used. Look at Coverage Checker - Detailed View to see the channel numbers used for each multiplex.

The signal strength should not be higher than 80% nor lower than 50% for any of the multiplexes. If they are all correctly tuned to the same transmitter and the strength is above 80% then an amplifier would make things much worse, an attenuator is likely to make things better.

Not sure who to ask, please redirect me if you can.... As of this morning- 5th Feb - my TV has message "no or weak signal, check antenna". Didn't have time to investigate before work. Returning home, same message. Checked bedroom TV, same message. We have had very high winds over the last few days but I'm hoping this isn't us. It's pitch black outside so can't see until morning. My question, any chance this is the transmitter and not my aerial? We're on digital HD freeview and our town is SKIPTON (BD23)

Thank you in advance,
