Freeview reception at CF83 2SS

Terrain between CF832SS 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.Internet Explorer 9+, Firefox, Opera, Chrome, and Safari required.

Will Calder: HD channels are in the 10x and 11x range and they are never in the 800 range as that is where receivers put other channels that are usually duplicates. So for some reason your receiver is putting the HD services in the 800s rather in their native positions.

The reason for retunes is probably because the broadcasters are forever adding new services and removing ones. These aren't the mainstream ones so the message is generally a nuisance. With PVRs it means loss of programmes set to record.

But since the broadcasters started retunes they have become more and more prevalent -- like an addiction you might say.

I'm not familiar with many receivers, more a technical bod, so is there an option in the set-up which allows you to turn off the annoying retune notifications?

Please, where can I find the compression format and bitrate of a Freeview radio broadcast, with particular reference to BBC Radio 3 transmissions? Appreciate any help.

I'm on the Guildford transmitter if it makes any difference.

Andy:
We really need some idea of where you are and what equipment you are using. The location, given as a postcode (or that of a nearby shop or post office) helps to show which of the many transmitters might be the preferred option, it also helps to show what the terrain is between you and that transmitter as hills/buildings in the way can affect reception. That assumes you are using Freeview. If, however, you are using Sky or FreeSat, then different considerations apply - hence the need to know what equipment is in use.

Hi, unfree reports possible weak signal from winter hill (granda) which we have been experiencing now for a couple of weeks. Any idea when it will be back to normal. Loft mounted high gain arial pr29sd. Previously consistentlystrong signal.
Possible 4g interference?
Thanks

Roger: Since all indications are that your signal should be really good, it sounds like you have a problem with your aerial. Start with checking the basics, such as the aerial lead from the back of the TV. Ultimately, you might need to call out a professional.
