I have now lost all signal can you tell me what the problem might be?
Brian Butterworth published on UK Free TV The problem could be one of:
- the aerial has been moved or damaged;
- the cables or connectors that connect the digibox to the aerial are damaged;
- the digibox has broken.
If you have a "spare" digibox you use this to test the aerial connection. Can you still watch analogue TV OK?

Your location is not predicted to have good reception of most multiplexes unfortunately. There is not a problem with the transmitter. I'd suggest that you check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what signal strengths and quality you are getting for the multiplexes shown in your Box/TV's tuning section. Also check that your downlead looks undamaged (especially if it is old) and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
For reference, the correct UHF channels for Tacolneston are C40, C43, C46, C42, C45, C39, C55, C56, C32 for multiplexes PSBs1-3, COMs4-8 & Local. If you don't have a HD tuner ignore C46/C55/C56. Reception of multiplexes will depend on location especially COMs7&8 & Local which may not be received.
Having said the above, currently there are interference issues. If you still have problems after this clears up, you might be advised to get a local aerial expert to check you have the optimal installation for your location.
There are unusually high levels of "Tropospheric propagation" at present, often associated with High Pressure weather systems.
These levels of propagation are unusual at this time of year - they cause signals from more distant transmitters to travel a lot further than normal. It is currently affecting different parts of the country by varying degrees and signals can change by the second or remain stable for much longer periods.
In the old "analogue" days there was a lot of talk about "continental" interference often in the summer months, but the interference can come from transmitters anywhere in the UK or Europe and even further afield. At the moment some people are getting DAB radio from the Netherlands and FM Radio from France as well as the interference to DTV.
It is predicted to continue for a couple more days, and you are advise NOT to retune as you will likely lose the correct tuning that you had. The "propagation" can be very frequency dependent, and it can only affected one frequency or several, but it can/will be different for others.
People will however have noticed the unusually mild weather which the Met office is referring to as a "Foehn effect" but it's not helpful that it seems none of the major broadcasters are making any reference to the interference being caused to TV and Radio reception! So it's no surprise that people wonder what is going on and think there is a transmitter problem.
For those that have retuned and lost correct tuning, you will have to try again and it could be hit and miss whilst the unusual propagation continues. If you are able to do a manual tune for the correct UHF channels, you may still receive interference or the wrong programmes.

Please note the above. You are predicted to get Good reception from the Heathfield transmitter under normal circumstances. The correct UHF channels for Heathfield are C41, C44, C47, C40, C43, C46 for PSBs1-3, COMs4-6.
If you don't have an HD tuner ignore C47.

Hi. Looking for advice after loosing all of my signal from the Chatton transmitter. All signals disappeared around 48 hours ago but then reappeared as normal yesterday for around 4 hours in the afternoon but went again and have not returned. We have had a full new aerial and cabling system installed on the 3rd Jan which has worked well with no issues.
I noted on freeview.co.uk engineering page that chatton for Berwick (where we receive our signal from) had planned engineering work on it's relay this week so hope that this is the cause of the problem not our new system. It states interruption to service possible. Is there anywhere we can get information on this work and its probable effect on our service.
We have two TV's one through a BT box and the other direct from the aerial source.
Cheers

We have no picture or sound and have decided we need a new aerial.
We bought a sony bravia 32 inch tv but didnt realise it couldn't pick up itv hub or channel 4 online.
With these factors in mind plus wanting to split the signal to an older digital tv upstairs, please can you advise me on aerial purchase?

I'm afraid we can't advise without a full postcode to look at the Freeview Detailed Coverage Checker to see what predicted reception is for your location. Otherwise you may be better checking with some local recommended aerial suppliers/installers.

Hi, my signal is intermitant. it is actually disgraceful. it is unwatchable. i'm not the only one either. sometimes there is no signal at all. i live close to cromer. is that the reason that the signal is low? are we too far away? if so then another mast should be erected! i and others pay good money to watch freeweiw chanels. so please do something about our awful signal.
please do not blame atmospherics.
regards Shirley cooper

This is an independent help site, we aren't responsible for the transmitters or broadcasters, but can provide free help and advice.
Your signal might be intermittent for a number of reasons but we'd need a full postcode to see what the predicted reception is, and from which transmitter(s) at your location - there could be several choices, the Freeview Detailed Coverage checker doesn't work on place names or partial postcodes. Apart from the postcode please advise in which direction (roughly) your aerial is pointing.
Other than that, it may be worth checking all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what signal strengths and quality you are getting for the multiplexes shown in your TV's tuning section. Also check that your downlead looks undamaged (especially if it is old) and that your aerial seems intact and pointing in the correct direction.

Since we did the latest retune in March we keep loosing all tv. We have a new digital aerial.
We live in Derbyshire which is in the East Midlands, yet freeview want us to use the West Midlands transmitters.

It depends on your location as to which transmitter(s) and multiplexes you might be able to receive. We need a full postcode for the Freeview Detailed Coverage checker to look at which transmitter you may be/should be receiving/able to receive. The retune should not have changed your region.

Hello
My aerial installer has advised the cause of a weak signal on some channels is due to them being tuned to the Craigkelly transmitter whereas the good channels are coming from Blackhill.
Would you advise the specification of a filter I could use to avoid the TV picking up Craigkelly.
Thanks
