Freeview reception at NG11+ 6JL
Terrain between NG116JL and Freeview mastsFor 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.

Many thanks for explaining the situation.
You are absolutely right, of course, to say that the local transmitter has far fewer channels than the main transmitter at Winter Hill. I never knew that before today but, having checked the relevant link, I now see that the local transmitter is, in fact, doing an excellent job of transmitting every channel it has available and that my two TVs and DVR are doing an excellent job of receiving them - even though the total is only 20 TV channels.
Having today taken a short walk up and down the road outside my house, I see that some aerials are pointed towards Winter Hill while others are pointed towards the local transmitter.
Interestingly, If I cast my mind back 30 years when I moved into this house, I do now recall an aerial fitter explaining that the Winter Hill signal would be impeded by two large trees about 30 yards from the house and that the signal would be even worse in summer when they were in leaf.
