Freeview reception at PGSTAR T50
Terrain between PGSTART50 and Freeview masts
For reliable and stable Freeview reception, you need an unobstructed path between the TV aerial on your roof and the digital TV transmitter.The diagrams below show the transmitters you can get a signal from - in order from best to worst. The blue line tests the line-of-sight between an aerial 10 metres above ground level (the line is red if there is an obstruction in the line-of-sight). You may be able to improve reception by raising the aerial higher - for safety's sake consult a reputable aerial installer if you need rooftop access. See below the diagrams for advanced options including selecting the receiver aerial height.
The terrain information (from Ordnance Survey and GIS) does not include forestation (where leaf cover changes with the seasons) or city buildings. The line-of-sight line can appear curved as this straight line moves over the Earth's surface.
When you click on a diagram, you will see map with the location selected shown with this symbol:

John: Dave is carried on COM5 multiplex. Have you replaced your Group A aerial with a Group K or wideband one? Do you receive COM4 (ITV3 etc) and COM6 (Film4 etc)?
I covered the post-switchover signals from Bilsdale not all being on Group A channels here:

Brian, I've had a look at your mobile phone masts for where I live (BN41 2HT) and it only shows 1 mast in the area - a generic E/Three mast. However when I go to the Ofcom site at Sitefinder Mobile Phone Base Station Database it shows 4 masts (at the corner of Fox Way and Foredown Drive) and that matches reality. Is your map supposed to show all masts, or am I expecting too much from it? Thanks in advance - PC (BN412HT)

mr f reant: The first thing is to ensure that ensure that the TV is tuned to the transmitter to which the aerial faces. In your area, reception may be possible from Winter Hill and Congleton transmitters. The latter carries fewer channels (the Public Service ones).
If your aerial faces Winter Hill, ensure that your TV hasn't tuned to Congleton (for the channels it broadcasts). To do this, check the signal strength screen on BBC One, ITV and BBC One HD (if it has a HD receiver). It should tell you the UHF channel that the signal is being received on and this is equivalent to the frequency.
For BBC One it should be tuned to C50 (706MHz) for Winter Hill rather than C44 (658MHz) for Congleton.
For ITV it should be tuned to C59 (778MHz) for Winter Hill rather than C41 (634MHz) for Congleton.
For BBC One HD it should be tuned to C54 (738MHz) for Winter Hill rather than C47 (682MHz) for Congleton.
You don't need to check others because they will be as one of the above. That is, BBC Two will always be the same as BBC One.
Further advice on your reply.

mr f reant: I would like to add that knowledge of the make and model of your receiver (TV or box) "may" allow me to find the user manual online and so give you more exact instructions on what to do.

Peter Challis: only masts that are likely to be used for 4G at 800 are shown. Others are irrelevant for TV reception and are excluded.

I have just recently moved into a house in Blackwater, unable to get any signal through the aerial fitted on the roof. We have had BT install infinity and we can now watch our main television via a booster but unable to pick up any signal for any of the other tv's even using an indoor digital aerial. Any ideas?
