Freeview reception at CO15 5AR


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.

Stephen: If your aerial is pointing to Oxford (Beckley) you will have to wait a bit longer for the COM7 transmitter to enter service. There is no precise date given for this, as yet, just due during 2014.

Post code LU7 4AW. Your system does not recognise it but, believe me, the Royal Mail does!
When we moved in to this new house three and a bit years ago, with new tv installation, 4 new tv sets, everything worked superbly - we had all the stations that we wanted, and more, good picture and sound.
Then, somewhere around the beginning of the year, the signal disappeared for longer than it is present. This week, we have been able to watch on Sunday evening and this morning for approx. 27 minutes between 0820 and 0850. Otherwise, we have a white on blue announcement that says 'Stream not available' and a red sign that says 'Off 10', which then counts down to 0.
I have done all of the checks suggested but am still being deprived of, what I consider should be, normal tv service. It is almost enough to drive me to buy into Sky, which really would be desperation!
To add insult to injury, my ISP is now threatening to start charging me for excessive broadband usage because the only way we can watch television is on my computer.
Help!!

Philip Hind Woodward: You aren't in an excellent reception area for any transmitter. Digital UK Coverage Checker proposes three possibles, neither of which are sparkling:

Coverage Checker - Detailed View

(Coverage checkers should always be used as a guide and results taken with a pinch of salt owing to the fact that they can never be in any way totally accurate.)

First up, Oxford at 24 miles and on a bearing of 249 degrees. The terrain plot shows obstructions at approximately 2, 3, 4 and 6 miles out:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


Sandy Heath at 23 miles and on a bearing of 47 degrees is obstructed due to the high ground at Herne Grange:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


And Crystal Palace at 41 miles and on a bearing of 142 degrees is obstructed quite a bit. The ground somewhere between Hemel Hempstead and Dagnall would appear to be in the way:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


Google Streetview photos were last taken in April 2009 and therefore do not show your road, as do the satellite images. Along Johnson Drive, however, there are large aerials mounted high up pointing in various directions (to the three transmitters identified). This merely adds weight to what I said about being in a poor area there is no overal winning transmitter.

So, your postcode is of little use in identifying which transmitter you are using. I doubt Royal Mail will know which way your aerial is pointing.

The only thing I will say is that your area appears to be one of development, so could it be that a building has gone up in the signal path (the line between you and the transmitter)? There are quite a few industrial units which could increase difficulty from one or more transmitters for some.

Ensure that you are tuned to the correct transmitter, although it would seem somewhat unlikely that at least four receivers are all tuned incorrectly.

If all channels are lost then this may suggest local interference of some kind, this often being pinned down by an AM radio. But if you are using a single aerial with powered amplifier then it is worth removing the amp and connecting a TV directly onto the incoming feed, if the amp is accessible.

Philip Hind Woodward: "If" you do decide to go down the satellite route you do not have to have or subscribe to Sky in order to get it. Freesat is the free-to-air platform you might want to look at.

Dave Lindsay: many thanks for the considerable effort you obviously put in to compiling the response to my posted query. That is very much appreciated.
Ironically, we started to get good pictures and sound from about an hour after posting the problem. And that appears to have continued up to the time of writing (1955 hrs 28.02.14)
The one thing that totally baffles me as a complete layman in these matters is how, without any apparent change in our domestic arrangements or in the surrounding environment (buildings, hills and other interventions cannot appear in minutes), the signal can be present, or not present, or vice versa.
At the moment, all is good so, many thanks for your virtual influence!

Philip Hind Woodward: Based on the fact that good signal ceases then that could be caused by local interference from noisy electrical equipment. For example a thermostat or noisy motorised port valve in hot water/central heating system.

Such a device could be in an adjacent property. The fact that you may perceive there to be nothing in your house to be a possible cause doesn't mean it isn't in your house; it may be a largely autonomous system.

Philip Hind Woodward: Does your signal come and go at any particular time? (in which, sounds just like local interference), or does it happen more randomly?

I'm just wondering if your system has a fault/break which manifests itself during wet weather, etc. Moisture can get into a broken coax cable, and kill your signal, but be ok when its dry.

Hi Brian,
Is there a problem with the coverage maps for COM 7, 8 on Oxford? The maps for these two show as virtually the same coverage as the BBC A which is 100Kw. COM7,8 are only 5.8Kw and unavailable in Westlea Swindon SN55XN which show up bright green on the COM 7, 8 maps. Also its the same with the Mendip COM 7,8. Are there any plans to increase the power of these?

Garth Sycamore: The power reductions are actually partially compensated for the change in transmission mode to DVB-T2.

The yellow bits showing for COM7 and COM8 are down the network being made up of only three frequencies per multiplex: you get bits of overlap. However, the overlap might actually be additive, rather then interfering.

It's worth remembering that the receiver power level is computed by taking the transmission power and dividing by the distance SQUARD. This means that lowering the power from 50kW to 6kW is "only 9dB".

The DVB-T2 services are actually at same power than the old pre-DSO Freeview services.

My daughter bought a new tv and set top aerial.She lives in a ground floor flat with no external aerial provided.She can receiver most channels.The only ones she cannot receive are the Mux D3 & D4 channels,which indicates all channel 44 stations,if as your site says she receives from the Wenvoe transmitter.She has tried auto tune and manual tune.The Samsung Tv has a built in freeview tuner.The transmitter at Wenvoe says it has no problems.Apart from buying another set top aerial with an amplifier,have you any suggestions.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.
