Freeview reception at S40 4JW

For reliable and stable Freeview reception, you need an unobstructed path between the TV aerial on your roof and the digital TV transmitter. The map below shows the transmitters predicted to provide a signal at this location.

You can click on any transmitter symbol to show the coverage area as a green overlay on the map. Double click on a transmitter symbol to go to the transmitter information page.

You can also view the ten closest potential '4G-at-800' mobile phone masts within 1.5km of the selected location - these masts may be used for 4G-at-800 mobile broadband services from 2013-2015.

Michael: Again, it is all down to commercial operators operating where they see fit. Sky doesn't "block" channels it's that they're only available on a subscription basis.

Channel 5 was offered the slot on the PSB3 multiplex which is nationwide and carries HD streams of BBC One, BBC Two, ITV/STV/UTV and Channel 4, but it turned it down which is why BBC Three/CBBC is carried there.

With reference to the example of Dave, it is available free-to-air on one of the Commercial Freeview multiplexes, which serve all but about 8% of the population which can receive terrestrial signals. What you must remember and which is logical is that it's objective is to maximise revenues so as to turn as big a profit as it can.

It pays to go on the Commercial Freeview multiplex. We must assume that it's better off to make itself available via satellite on a subscription basis (via Sky) than pay to be free-to-air on satellite (Freesat and Sky).

The point is that the cost of paying to be available to most Freeview viewers is obviously worthwhile when set aside the advertising revenue it generates from those viewers.

And, if it were to make itself available on free-to-air satellite then it would be worse off than it is now because it would have to pay to be on there and wouldn't get any revenue from Sky (if indeed revenue flows to it).

It's all a case of cost-benefit analysis, as it always is in business. We must assume that the status quo is the best for it, and the above explanations would seem to be the reasoning behind what may appear to be a bizarre situation (Freeview users getting it free-to-air but satellite ones having to pay).

Most Freeview receiver devices (TVs, Freeview boxes, Recorders, etc.) can display signal strength and quality. Signal strength is obvious, but what contributes to the quality level? Depending on the equipment being used the quality level displayed can vary widely between receiving devices despite them deriving their signal from the SAME aerial.

Mark Heselden:

The 'measure' of signal quality is a very subjective matter dependent entirely on how the software used in the particular TV/STB has been written. They all vary, even within the same make but different models.

It is meant to give some indication of how well, or otherwise, the decoder system is sorting out the actual data carried within the multiplex signal for the programme that you are watching/'measuring'.

I have a TV with a DVB-T2 tuner/decoder built in and a STB that is DVB-T only. If I check the signal quality of the same programme, I used BBC1 SD from Mendip for my check just now, the quality is shown as 90% on the TV and 75% on the STB, both being fed from the same log-periodic aerial through an active splitter. Swapping the feeds round so the STB had the input that was originally to the TV (so eliminating any variance due to cabling, etc) gave exactly the same figures. That shows the software design and implimentation is the variable factor.

All you can deduce from the quality indication is whether the signal is able to be decoded or not. Elsewhere on this site is a discussion about what happens when you have too much signal, usually shown by a 100% strength reading. In some cases the TV/STB shows a message suggesting there is no signal when in reality it has too much signal and it can't decode it so the quality is shown as 0, hence the 'No Signal' message that is actually incorrect. A similar situation occurs when there is too little signal though most receivers will show some programmes but not others, the weaker ones not being decoded. In that scenario the strength is usually well below 40% but I've seen quality as much as 60% even though it is having problems decoding!

So, to summarise, it's only an approximate hint but can be misleading. All you do know is that if it shows a very low quality you could have problems viewing some programmes. You also know that if the signal is too strong then that could lead to reception problems as well.

Hope that helps?

Thanks very much Mike. That does shed some light on it. I had been puzzling over the quality level issue for a while.

marilyn feaveryear: As no faults are indicated (as yet) on either the Tacolneston or Norwich Central relay, nor is any engineering work taking place at either station, then this is inclined to point to something having happened to the aerial system, is the aerial system or the cables from, communal in any way?

The other point being, that if you have tried resetting the TV's, (your neighbours and yours) then this will have deleted the channels already stored in the tuners, this then requiring frequent retunes in an attempt to recover them, whereas the signal would have returned of its own accord if the receiving devices (TV or box) had not been retuned.

Its never advisable to try resetting a TV nor carrying out a retune when a no signal message is seen, as the reason for the problem is very seldom ever connected with the actual TV or box.

Everytime I enter a post code etc. regardless of where in the UK this shows me that my transmitter is the Crystal Palace one. Well I've got news for you - it isn't! I certainly do not receive signals from London in Shetland, Aberdeen or near the South Coast of England. Get it sorted please.

Bourne End

Similarly Bourne End in Bucks mostly gets Freeview reception from the Wooburn Freeview Lite relay of Crystal Palace and NOT the High Wycombe relay. If you look at the map generated by putting in my postcode, in fact most of Bourne End is showing as having no reception at all from the High Wycombe transmitter! Please look into it (or advise who does). An explanation of what's gone wrong would also help as if it's just one person responsible for this tools accuracy when there are more than 1000 transmitters to be taken into account, that's a little different to if it's a large corporation responsible for feeding the information and accuracy checking.

I entered my postcode PH23 3NA and you gave me the Light Freeview coverage from the Grantown relay - however I note some houses in the area do have aerials pointing to Knock More (horizontally polarised) which will give them the FULL Freeview service.
Can you tell me what type of aerial would be needed for Full Freeview at PH23 3NA (Lochanhully Woodland Club, Carrbridge)?
Thank you.

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.
