Freeview reception at AB51 5QX

Terrain between AB515QX 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: .Internet Explorer 9+, Firefox, Opera, Chrome, and Safari required.

Thanks for the responses; I now have 3 differently rated attenuators. I found that using an attenuator with the August media player (tuner) DVB-415 failed to stop the 'jerking' picture. (Note, the picture is fine without an attenuator when using the sister August DVB-400).
Another problem with my Passion+ satboxes, where I get "jerky" pictures on BBC and CH4 HD channels, but not ITV HD when used with my Tevion TV, was NOT apparent when I watched "The Open" on BBC HD on my Sharp TV (newer than the Tevion).
The Passion+ has the option of selecting the rastor (there's a term we don't see very often now!) lines. This leads to the question: if the Passion+ is set for the maximum 1080i what is the effect if the TV operates at 1080p?
