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).

John G : Meant also to say, that should the old TV be coupled up and this results in the reception reverting back to normal then could you please supply the model number of the new TV.
Another point being, if a booster is being used in the aerial system then try bypassing it, especially if the new TV is an LG or Samsung, as the tuners in those brands are rather more prone to suffering from the effects signal overloading.

Stewart Smith: There's no such thing as a "analogue aerial" just as there is such thing as a "digital aerial".
An aerial's design is based on working across a particular range of frequencies. In the case of Wenvoe, which I guess is where your aeial might be pointing, aerials installed in the days of analogue would be expected to work, as all main channels are within Group B (that of the former four analogue channels).
If you decide to get a Freeview HD receiver - which isn't a bad idea considering that in 5 or so years' time some signals "may" switch to DVB-T2 - then you might be able to receive the new quasi-national HD services of BBC Four, CBeebies, BBC News and Al Jazeera (with more to come in the future). For these you "might" find that the existing aerial isn't good enough because they are below Group B on C31. See:
Aerials, TV Aerial and Digital Aerial
In the UK there are two digital terrestrial signal standards: DVB-T and the later DVB-T2. "DVB" stands for "digital video broadcasting" and the "T" is "terrestrial". At present standard definition broadcasts use DVB-T and high definition ones use DVB-T2. Thus a "Freeview HD" receiver can pick up DVB-T and DVB-T2 signals. So if, in the future, some standard definition signals were to be changed from using DVB-T to DVB-T2, what is presently known as a "Freeview HD" receiver will be required.

Stewart Smith: You are indicated as being able to receive Freeview from either the Wenvoe transmitter located at 15 miles / 233° or alternatively the Mendip transmitter at 29 miles / 146°.
As far as the aerial is concerned, aerials do not distinguish between transmission modes no matter what some advertisers may suggest.

John Randle: Too much signal maybe.
Check that it's tuned to Salisbury on C57 and not Rowridge on C24 for BBC by viewing the signal strength screen.
Something to do with extra wires near the TV owing to the Christmas tree lights, maybe.

Stewart Smith: On the subject of your aerials suitability for reception from either transmitter, then to be strictly correct as far as accommodating the new muxes are concerned it should really be changed to a wideband version such as a Log 36, this version also catering for the possibility of reception being affected at any time by 4G transmissions, a supplier of the aerial referred to being accessed by opening the link.

JB38: The new TV is a Samsung UE40F5000AK. Is it likely that the problems with reception are down to receiving too high a signal strength from the Dover transmitter? From what I can see from this website the straight line of sight to the transmitter has no terrain constraints and therefore nothing but open fields between it and the aerial in the loft.
There is no amplifier in the system, just the aerial and wiring. Thanks for your help and hope you are having a good new year.

John G: Yes, the terrain indicator does indeed indicate a good clear line-of-sight even when using the more detailed Megalithia checker.
However, as your aerial is positioned in the loft and with the signal output from same not being boosted in any way, then although the issue of tuner overloading is not completely out of the question I somewhat doubt if it applies in this particular instance.
As far as the problem is concerned, although temporarily substituting the new TV for the old one would instantly indicate if the aerial is still OK or not, but should this create a problem then there is another test you could carry out that would be of considerable assistance, this being to carry out a signal strength / quality test on BBC1 making a note of the levels seen followed by the same test again but on ITV1 likewise noting that seen, the main point of the test being to observe the levels seen over a period of at least a minute or so in order to check if the quality is detected as having any tendency to dive up and down, and if it does is the fluctuation also noticed on the strength?
If though not all channels are being affected then just carry out the test on the ones that are, but still noting one that's OK to use as a reference reading against the others that aren't.
Another way to check the signal strength / quality levels is to go into the tuning menu / manual tune and enter the mux channel of the transmitter you want to check, but this action NOT being followed by pressing search or scan, as on most devices as soon as the channel number is entered the strength / quality of the signal will be indicated.
Dovers mux numbers being /
50 (BBC1) - 51 (ITV1) - 53 (HD) - 55 (ITV3 etc) - 59 (Pick TV etc) - 48 (4Music etc)

living in a mainly forest area IP27 0 i do not expect good signals, but keep losing sandy heath and tacolsten is a virtual no go. radio is as bad. could this have anything to do with the US airforce base pumping out.

alan: If you look at the Terrain plot and Digital UK lonks, you can see that your just unlucky. You've got high ground near you blocking the signal from Talconeston (your closest), and Sandy Heath, as you say, isn't exactly close, and with possible high ground in the way as well. Yes, your bascially in Thetford Forest, which doesn't help either.
I suspect that the USAF has nothing to do with it (or all of us in East Anglia would get nothing!), but would personally advise you to go down the Freesat route, because you could thrown a lot of money at getting a solution, for little result.
