Freeview reception at 51.3968°N -0.769°E


Terrain between 51.39687629420501,-0.76935355170 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.

Morning Chris
Our aerial is on the roof/chimneystack.
I've re-turned our 8yearold Ferguson on 'Autotune at least ten times (although not this morning - 24/11/19)channel 4, ITV, and channel5 are all almost completely intermittent/breaking up
I'm going downstairs to have another retune/autotune go and will let you know if everything puts itself right (???)

Tom Richardson:

It might depend on when you previously retuned, and which transmitter you are actually receiving/wanting to receive. There has been Planned Engineering at Pontop Pike and Bilsdale this last week with "Possible service interruptions". You are predicted to get good reception from both of those.
There is also a low power relay closer to you (with variable/poor reception) which you may have got inadvertently tuned to if you retuned when your chosen transmitter was off-air. It's not a good idea to retune when a transmitter is off-air, you just lose all your correctly tuned channels!

I suggest you try the following first - unplug the aerial and do an automatic tune. This should clear all previous tuning as no channels will be found. Then plug the aerial back in and repeat the automatic retune which will hopefully restore all multiplexes correctly. (2 -PSBs, 3COMs and a Local if your set doesn't have an HD tuner).

If you are receiving Bilsdale (best choice & closer) your aerial should be pointing ~SSE (163 degrees) with the rods horizontal.
If you are receiving Pontop Pike your aerial will be pointing ~NE (315 degrees) with the rods horizontal.

If your set has the option the see which UHF channels it has tuned to for each multiplex or indeed allow a manual tune if autotune doesn't resolve the problem, the channels are as follows in the order PSB1&2, COMs4-6, Local, for the SD channels, + if you have HD PSB3, COMs 7 & 8 -

Bilsdale - 21, 24, 43, 46, 40, 30 + 27, 55, 56, you may struggle with reception of the COMs (SD &/or HD) if you have an old Group A aerial.
Pontop Pike - 39, 42, 32, 34, 35, 33 + 44, 55, 56, you may struggle with reception of the COMs (SD &/or HD) if you have an old Group B aerial.

Note, you only may struggle with reception of some multiplexes with old aerials, a lot depends on location and distance to the transmitter. Ideally you need a Group T/Wideband to get all multiplexes reliably.

I had an ariel put in the roof because I wanted to receive Meridian news (previously could only get London news)
However,there are some channels that keep stating 'low signal' even when the weather is not too bad,so I view through my Humax box which is better but then all I get is the picture stop for a second or so and I lose a few words of dialogue.I also thought that at my address RG12 2QJ I received from the Hannington transmitter but when I went into your website and put this info in it stated I was geared to the Crystal Palace transmitter,but I could not find any reference to my area at all - can you please explain

Mr A.Squires:

Sometimes predicted reception can be quite variable when you live in an area that has overlapping coverage from more than one transmitter particularly if you are on the periphery of these areas. It looks as though you could have line of sight to several transmitters depending on your precise location within your postcode. It can be especially tricky if the location has local obstructions or is a bit hilly which could be the case with you.

The official Freeview Detailed Coverage Checker does show such variations across your postcode, but mainly good reception from most of the main 6 multiplexes and also the COMs 7&8 multiplexes depending on your precise location. Similar results are obtained from the BBC's RTIS predictions. Both show good or variable reception results from Hannington and Crystal Palace and again they change with precise location.

This means that good aerial location will be very important as will the choice of aerial needing sufficient gain and appropriate beamwidth/polar response. Local weather conditions can also have significant effects on loft mounted aerials, as can the presence of water tanks, walls & etc.
When more transmitters share frequency (UHF channel) usage around the country as is more the case now, changes to reception can occur in some weather situations and when transmitters might be undergoing planned maintenance or have faults. It is also important that your own installation is free of faults.

One thing you can do is check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what signal strengths and quality you are getting for the multiplexes shown in your TV's tuning section. Also check that your downlead looks undamaged (especially if it is old) and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.

If you have frequent problems with specific channels check https://www.freeview.co.uk/corporate/platform-management/channel-listings to see which multiplex they are on, as reception of some multiplexes can be variable in a particular location.

Mr A.Squires:

I should have added that for Hannington your aerial should be pointing at a bearing of 250 degrees - that's marginally West of WSW and the rods should be horizontal. The precise direction may vary by a few degrees for best signal strength depending on aerial location.

Your comment please
Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
