Freeview reception at DE55 1DL


Terrain between DE551DL 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.Internet Explorer 9+, Firefox, Opera, Chrome, and Safari required.Internet Explorer 9+, Firefox, Opera, Chrome, and Safari required.Internet Explorer 9+, Firefox, Opera, Chrome, and Safari required.

Firstly there is no such thing as a 'digital' aerial. All UHF aerials of a wideband type will receive all the available signals, the type of modulation does not affect how it is received.

Secondly, please check all your aerial cables and connections, if there are coaxial plugs/sockets please unplug those and the refit.

Thirdly, check the signal strengths of the affected multiplexes, You want to have between 60% and 85% ideally, too much or too little gives bad results.

That's because the owner of this site has not updated the link handling as he is unavailable at this time. No one else can do that.

700MHz clearance is the project of rolling retunes to better arrange the Freeview transmission frequencies, so they can be used in 2020 for 5G mobile data. It was blogged about here, but not integrated into the site's many features.

Having spent a whole day gathering the change information for 300 transmitters and placing them in a database table, I was able to re-code four of the UK free TV features to use them. These are the technical prediction system https://ukfree.tv/prediction where all change dates are showing...

See Updates for 700MHz Freeview retunes, fixed all channels, new icons, radio fixes | free and easy for details.

Thanks for the updates (and the 23 emails ;-)

The TV mapping view doesn't seem to be working for Stadhampton (51.6885?N -1.134?E) in the latest Firefox on W10. There's no green area shown initially, and if you try to click on the bouncing Oxford icon, it doesn't work. It does if you click on the static Hannington transmitter. Clicking on the static Oxford then still doesn't work.

Same here. Using Firefox at SN5 4ET, I just get mobile phone masts and nothing happens when clicking on 'Freeview Coverage' at top left of map.

And in the 'Predicted Freeview channel list' my only 'predicted' transmitter is given as Seagry Court which is a light transmitter which has never been any use to me.

Rex Bartlett: Seagry Court became a full 6 mux transmitter and received an increase in power level earlier this year and looks like the best option for reliable reception at your postcode.

Rex Bartlett:

Further to that saod by StwvwnsOnln1, Seagry Court is by far the best transmitter for you to use at your location. Both Oxford and Mendip give poor and unreliable reception in your part of Swindon. If you go to the Digital UK Covergare Checker for your locations, see http://www.digitaluk.co.uk/coveragechecker/main/trade/SN5+4ET/1/0/731pqia0j2f2135drvppbqpcf6, and scroll down to the Seagry Court entry it will show all 6 multiplexes should be available with good and reliable reception. It will also show you the channels used for the transmissions to help you tune your TV manually.
