I have SEVERE issues recently with some freeview channels, notibly Sky news. At the moment I have NO signal, whereas I used to receive this without problem. I live in Dorset, not far out of Poole. Could this be a 4G issue and, if so, what do I need to do to overcome the issue? Who do I contact? ALL HELP GRATEFULLY APPRECIATED..... PLEASE!

Alan: It would really help if you could post a postcode, since it will show which transmitters you might be using.

Rather than 'no signal', are you just not picking up Sky News? If your not, it could be that your tuned into a local 'light' transmitter, which doesn't carry it, rather than Rowridge.

4G problems are actually really rare, so it highly unlikely, but it could be a problem with your aerial lead - so check your system for any breaks, etc, to make sure your signal is consistant across the full range.

Many thanks JB for your help (last month, sorry for delay!). Managed to get Channel 5 by realigning aerial slightly and a reset of hard drive tuner.

Thanks to jamie stevens and jb38 for their comments on 4G

The nearest transmitter to me is about about four city blocks away high up on a multi-storey car park. Its transmissions will hit my aerial from behind if that makes any difference.

I don't have any amplifications and my new aerial is a Yagi 18A (the old one was a standard Group A job which I think was better but time may well change my opinion of the Yagi.) I opted to stay with HP rather than VP because I get very good reception of the local tv signal (which at 10kw is very low) and I enjoy POP very much!! although I know it will disappear eventually. But I can always go VP should I ever need to.

Anyway I'll wait and see what 4G brings...I understand from my local Orange shop manager that it should come alive in about two weeks time (the nice man is going to alert me by email once its operating so I'll know what to look for come the day.)

As for the shadow problem I'm experiencing I didn't have it with my Group A aerial and it seems to have appeared overnight sort of thing so I'm wondering if some sort of obstruction (maybe a crane or the like) has gone up in between my aerials line of site to the transmitter and I'm getting some sort of reflection off of it. Would that sort of scenario make any sense?? I certainly don't think it's my tv as I have a 32inch Sony Trinitron crt type set and I'm pretty sure crt's don't suffer from shadows and ghosting like some of the the modern sets can. I've also tried another set top box with no improvement so I can rule that possibility out as well. Anyway I'll have to put up with it and just hope it disappears as quickly as it appeared. If necessary I can always get the Yagi double checked out as it came with a years guarantee on the works so there is that to fall back on if the problem doesn't go away.

colin1951uk: Signal strength indications taken from rear pick up can on some aerials not be that terribly far removed from the levels obtained from the front, likewise going by what you have mentioned with regards to the location of the 4G transmitter to that of your aerial does place you at a slight disadvantage to others in your area but who are located a different angle to yourself, whereby the 4G transmitters signal would be striking their aerial from the sides, albeit of course possibly still not at the ultimate angle for minimum pick up, namely 90 degrees. However, the fact of you having a group "A" aerial does up to a point give an element of protection to your reception due to the efficiency of the aerial tapering off from C37 upwards, therefore if by any remote chance you did suffer from the desensitizing effect of 4G then the addition of a 4G filter in line with your boxes aerial input is almost guaranteed to eliminate the problem. As far as the 4G service is concerned, if its expected to be up and running in another two weeks or so then the chances are that the transmitter "might" already be in operation for test purposes, but though irrespective of whether it is or not you should carry out a signal strength on the following channels, keeping a note of the readings obtained to use for reference purposes against a second test taken "after" its known that the service has officially started. Of course, the purpose of this test is purely to find out if your tuner is being affected in any way from the effects of the 4G signal should nothing have apparently changed by the time you are notified, because if the tuner is being affected the indications previously taken will all have dropped slightly. Test channels being / C24 (BBC1) @ 200Kw / C25 (ITV3) @ 50Kw / and either C31 (24Kw) or C29 (10Kw) making a note of the readings obtained. As far as your TV is concerned, I have to agree with Jamie insomuch that its most likely to be the TV at fault, basically because digital reception does not suffer from ghosting, this effect purely being associated with analogue TV reception due to such as signal refection from hills etc, although another thing that can result in a form of ghosting (or ringing) is "if" the analogue signal being fed into the TV's scart socket is a little on the high side whereby is overloading the signal processing circuitry. If possible, you should try and check your system out on another TV, secondly is your TV coupled into your Freeview box using comp video (CVBS) or are you using RGB? the latter being better by far!

Colin1951uk: Following on from JB38's point about how your signal comes into the TV, can I assume you have a digibox feeding into the CRT? If so, how is it fed? I'm guessing that its via scart, but are you also using something else, like a scart switchbox?

I know that I get interference from power cables with my scart from the switchbox (which is a bit dicey to change), so it could be the setup in the back of the TV, including a loose connection, etc. Just check that everything is tight, shielded, and away from power cables, etc - it might help.
Of course your TV is now at least 8 years old, so it might be the TV itself - you could check by using the same input lead you use for the digibox to feed something else, say a dvd player. Since you's tried another digibox, its more likely to be the cable or the TV, so at least try another cable. If its still doing it, then at least you've ticked a couple of things off the list.

Hi

We receive from rowridge, aerial is horizontal postcode is po34 in the last week we've been experiencing problems on Quest (https://ukfree.tv/mapsofsignal.php?c=25) and other channels on this c25.

We had full strength signal on all before the last 'new channels found' retune last week.

We have good sight of the transmitter but before I start climbing the roof and checking the cable I thought I'd check on here and I see someone else saying the same so I'm wondering could it be interference due to the Isle of Wight festival - stages, funfairs and additional mobile masts brought in ?

Or could it be 4g ? I don't really want to go buying filters if they're not needed.

Similar issue to you Damian. Receive from rowridge to PO3. Last week all was well, not receiving the BBC channels and ITV3.

MikeB: Just a note to say I tried a dvd player and the problem persisted and as I haven't got a spare scart lead I finally managed to borrow one from a friend. On using it hey presto the shadows have gone! So I'll have to get a decent quality lead off of Ebay (where I live all we have is Argos and their leads are rubbish) and that should be an end to the matter.

Cheers and thanks for the tip.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
