Freeview reception at IV12 5LF


Terrain between IV125LF 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.

Something did happen - at the bottom of your post are several small blue boxes as a result of your entering your full post code. Click on any of the boxes to see the details provided. The 'digitaluk trade' box shows that you should be getting excellent reception from Southway and Caradon Hill. Southway is a 'light' transmitter so only carried three multiplexes. Caradon Hill is a full service transmitter so carried all eight multiplexes. The relevant channels used are also shown.

If you wish to have a more immediate display of information use the Digital UK Coverage Checker at http://www.digitaluk.co.uk/coveragechecker and enter your full post code and house number.

At present I'm in Cumbria and moving to Liverpool. I notice that PBS America (chn 94) is not on Freeview in the Liverpool area. Why is that?

Roderick Barker: Most of Liverpool should be able to receive PBS America on the COM8 multiplex with an aerial pointed at the Winter Hill transmitter. It isn't broadcast from the Storeton transmitter. If you provide a full postcode we can see what the predicted coverage is at your new location.

I tried to use 'My Freeview' to check reception at the campsite in Charmouth where I will be holidaying next week. I tried DT6 6QS (with or without the space) - I got the reception conditions for the default latitude & Longitude of Crystal Palace. I tried the map reference of the campsite SY935367, all I got was - Crystal Palace again ! In desparation I tried one of the sample postcodes, I got the reception map for that area - with all the channel allocations for (yes, you've guessed it) Crystal Palace !!
There's a serious bug in the data entry field of 'my freeview' , unless you live at Crystal Palace that is. Please can you sort it ?

MikeP Channel 56 is now alive and well again here at IP17. I did replace the aerial cable to eliminate a join halfway, using the latest and greatest all copper cable, but making no other changes, and the signal was good without those alterations. Back to 80% signal and 50-100% quality. Earlier loss is unexplained so far I am concerned.

But thanks for your help and encouragement.

David Chappell:

I suggest you use the Digital UK Coverage Checker, that is provided by the operators, at http://www.digitaluk.co.uk/coveragechecker. Simply enter the full post code and a house number (if that is not available then enter a '1' instead). That will then show the available transmitters at the location given by the post code. That shows that reception is possible from either Charmouth or Stockland Hill. It also gives the direction to aim your aerial and the channels being used.

The unexplained always does come back! I had problems again today with Channel 56 and this time really dug into the problem. Mostly I was getting high signal level but minimal quality on c56 - odd and previously put down to interference or poor connections.

I now believe that what is happening is that my very local (1 1/2 miles) Aldeburgh Freeview Lite transmitter is overloading my TV and blocking reception of weak channels such as c56. I have an ultra high gain wide band aerial with a mast head preamp to get c56 from Tacolneston but I suspect it has a side lobe towards the local transmitter. Turning off the preamp improved c56 reception quality but made the signal so weak it was unreliable in that way. I have ordered an overlap blocking filter and hope this will do the trick. I doubt I am the only person to have this problem!

Chris:

I am glad we seem to be making progress. You surmise that a side lobe of the very high gain aerial is receiving unwanted signals is quite likely. However, just turning off the amplifier tunrns it into a high loss attenuator wioth much reduced signal feed. It would be better to take it out of circuit, even if only temporarily, and coupling the two coaxial cable ends together with a coaxial coupler, very inexpensive, so the signal is fed through in full. Worth a try?

Yes - I did do that and I think the blocking is stopped but the c56 signal is now undesirably weak. It's a difficult balance. The filter should arrive today and that will be interesting to try. Annoyingly it's a DC blocker so I can't rely on the power from my Labgear distribution amp to power the mast head amp. Fortunately I have a separate power supply I can patch in.

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.
