The symbol shows the location of the Limavady (Northern Ireland) transmitter which serves 45,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Hi,
For the last few weeks, COM4 has been breaking up really badly for me, while it was fine before that. I live in Letterkenny, Co Donegal. Reception was perfect before that. Is there any changes on ch54 which could be causing this? It was ok for a day or two ladt week but is totally pixellated again. Thanks!

Please provide a full post code, the website used to check expected reception only accepts full post codes. The name of an area does not help us to helop you.

F Byrne: There is no recent engineering work shown for Limavady, although there are several frequency changes taking place on 4th September. As you're in the Republic of Ireland and therefore don't have a UK postcode, I don't think the Digital UK checker will be much use. Have you checked for any loose or damaged cables or connections behind your TV?

As StevensOnln1 says the Digital UK - Coverage checker may not be of any help, but you could try it to see. You are quite a long way from the transmitter and parts of your locale are not (well) covered. Due to the changes coming up there may well have been undocumented transmission dropouts.
If you click on the transmitter postcode BT49 9LJ at the top of this page, it will open the checker at the transmitter site where you can at least see the UHF channel change due on the 4th September. All the multiplexes are moving, you could even try a manual tune for UHF40 to see if the SDN multiplex is already transmitting there (unlikely but some transmitters around the UK have occasionally started a multiplex on the new channel before the switchover date).

Thanks StevensOnLn1 & Chris.SE for your replies. Hopefully things will improve again after September 4. When the Freeview transmitters were on low power before analogue tv was switched off, we picked up all 6 UK muxes without any problem. Could be that ch 40 is being tested out, as you mention - some days it is perfect, other days unwatchable.
Now, I recently repointed my DAB antenna to point at Divis to pick up ch 11A .. I haven't tried moving it again to see if it is causing issues on ch 40, even if the DAB antenna isn't meant to pick up past ch 13 (the signals are combined into one aerial cable for the tv / radio ports in the house.
Thanks again!

Ok, I did the retune today. Even with my old yagi wideband antenna from 2009, all channels came in. Interestingly, the weakest channels are those on COM6 (Yesterday, CBS Drama, ...) On ch 46. Signal strength is 20% lower than the other commercial muxes. Same as before switchover - that mux is the weakest, even though your guide indicates it is the same strength as the other 2?
Either way .. no new / narrower aerial is required .. for now, anyway. My TV is too old to pick up the BBC HD mux, so can't test that at the moment
Question: is my 4G filter any use now to be kept plugged in, now that all the channels have shifted down? I'm assuming I'm losing a little gain with it inline but was not sure.

You can check your predicted reception by using the coverage checker Digital UK - Coverage checker if you have a UK postcode.
There will be some insertion loss from the 4G filter but it's likely to be very small, try it without and see if it makes any difference. The disadvantage of not using it may be that if you have any very strong 4G signals they may saturate your TV front end reducing the sensitivity hence reducing signal level of other received channels.

Thanks, Chris, for your reply! I live in Letterkenny, in Co Donegal. I'll leave the 4G filter in for now and see how it goes with the weakest mux. It was slightly damaged so if I unplug it, I might not get it back in, should it be necessary! If it wasn't for the fact my aerial is on the roof of a two-storey house, I'd be tempted to upgrade it to a K band aerial, since it cost 150 last time for installation..
Btw - thanks also for all the info you have on your website!

Hi, back again! A few weeks on, ch 46 is so weak that it is frequently unwatchable, such as this evening. I tried looking up your coverage maps but they do not appear to be updated yet post-5G changeover?
C46 (674.0MHz) after switchover | free and easy
The above does not show any channels from Limavady.
I've noticed that ch 43 can be unwatchable at times (mornings in particular) and then without any errors the rest of the day. Definitely far more interference since the latest changeover...
Ch 43 is stronger than ch 46 yet their apparent transmission power is the same.
(I'm in Letterkenny, at a high enough point where one time, I used to get ch21 from Divis, showing Channel 4).
