Freeview reception at 51.5473°N -0.009°E


Terrain between 51.547341,-0.009830 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.

Pauline Bell:

It's never advised to retune when you have no signal, it usually just clears your correct tuning and you end up needing to retune again when you have a signal.

Just tuned in a new tv. I dot seem to be picking up any COM4 or COM5 channel. No problem with previous tv. Am I doing something wrong or is there a problem with the transmitter?

Andrew: Do you still get the channels on the old TV if you plug it back in without retuning? We need to know where you are (please provide a full postcode) or which transmitter you're using to be able to check for any reported faults or engineering work.

This could be due to current weather conditions - temperature Inversion/tropospheric ducting to be precise, some of the predictions show there is currently some quite variable but strong conditions affecting parts of central England.
It sometimes comes with high pressure https://www.bbc.co.uk/reception/help-guides/freeview/how-clear-skies-and-fine-weather-can-affect-your-tv-reception & https://www.bbc.co.uk/reception/help-guides/freeview/effect-of-tropospheric-ducting-on-freeview

This type of ducting affects different frequencies by differing amounts in different locations, which is possibly why you are only currently seeing an issue with COMs 4 & 5. It can vary by the second or be stable for much longer periods. It can also affect FM & DAB radio & probably mobile phone signals but not to an extent that people have realised.

If you happen to use the Waltham transmitter, try a manual tune on UHF channels C29 and C37 for those two multiplexes as manual tuning will sometime resolve them when signals are suffering some interference as long as it's not severe at the time.

William Utley :

Well according to the Freeview Checker you should be getting very good signals from the Bilsdale Quarry mast.
Check that your aerial is still pointing the correct way - bearing 24 degrees ~NNE, in your locale. The rods (or squashed Xs) should be horizontal. Check that the downlead is secure and not flapping in the wind.
Check you coax plugs and leads are correctly plugged in etc.

Try a retune as follows - unplug the aerial and do an automatic retune which should clear all previous tuning as nothing should be found. Plug the aerial back in and repeat the process and hopefully all your channels will be correctly restored.

If you are still having problems, check in your TV tuning section that you are tuned to the correct channels for Bilsdale -
The UHF channels are C27, C24, C21, C43, C46, C40, C55 that's in the multiplex order
BBC A/PSB1, D3&4/PSB2, BBC B HD/PSB3, SDN/COM4, ARQ A/COM5, ARQ B/COM6, COM 7

Otherwise post back with more information about your aerial and any distribution amp/splitter etc.
