Freeview reception at BT48 7DD


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.

Ian Farrow: Hi, again Ian. Are you not aware that a UHF tv aerial on the roof is not of a suitable design to be used as a DAB radio aerial, although it is possible to use a 1950s or 1960s Band III ITV aerial for DAB radio reception, as long as the rods or elements point up and down in vertical planes. The quality branded models of DAB radio allow you to disconnect the telescopic rod aerial and connect an external DAB roof aerial, such as the type I've described above, using an F-type screw connector. It is always better to use an outside aerial rather than an inbuilt telescopic rod aerial and brand new DAB aerials can be purchased quite cheaply. One wouldn't consider trying to use a television set with a built-in aerial unless one was living next door to a powerful main transmitter, so if you're serious about receiving DAB signals from alternative transmitters, you need to invest in an external DAB radio aerial because, as i began this post, a UHF DTT or Freeview aerial cannot be used. If I lived where you do, I'd be keen to try an external DABaerial on Heathfield if Newhaven DAB was off! Richard, Norwich.

Richard Cooper:

Thanks again for further comments. Your technical comments are way beyond my comprehension - we are pensioners and can't afford to just change roof aerials willy nilly. Our TV reception is perfect on all channels and our roof aerial is also boosted by mains electicity and we have no problems there. Somewhere along the line the point I am trying to make is being missed. We get perfect DAB radio reception on all 5 of the radios in the house on the Newhaven 10B (Sussex) band and also on the Newhaven 12B (BBC National DAB) band - it is JUST the D1 National 11D band stations that have disappeared. I am not trying to receive from any alternative transmitters - I am simply trying to receive from the transmitter that was perfectly ok up until Friday 16 September.

Thanks for trying to help - I appreciate it. This did happen in about March of this year and we were without the same band for about 4 days and then suddenly everything appeared again, so I guess I must just be patient.

Ian Farrow: Hi again, Ian. Thank you so much for your replies including personal explanations. I should think that the Newhaven DAB transmitter will have the Digital One (D1) group of programmes back on air within a few days, because the programme companies soon realise that they are losing advertising income if a transmitter is off the air for more than a couple of days, so, 'Yes', you need to be patient if you cannot afford to pay out for an 'on-the-roof' DAB aerial in order to receive the Digital One stations from an alternative transmitter. Richard in Norwich.

Ian Farrow: Have you contacted any of the broadcasters of the stations on D1 that you are trying to listen to? They should be able to confirm if they are already aware of the fault or otherwise they can pass the problem on to the transmission company to investigate.

Why do the current local TV broadcasters only use horizontal polarisation for the low power signals involved as reception is not normally possible in an area not very close to the transmitter if the receiving aerial is vertically polarised?

Nick Anderson: Local TV is done on a tight budget, with broadcast patterns and power levels determined by Ofcom. I suspect you are referring to the Rowridge transmitter. The Solent local mux is only intended to cover Southampton/Portsmouth and the surrounding areas which should have good reception of all services with a horizontally polarised aerial, whereas the vertically polarised transmissions enable the COM4-6 muxes to broadcast at higher power in order to improve reception in areas further away from the transmitter which are not the target of the Solent local TV service.

Nick Anderson:

Further to that said by StevensOnln1, most main transmitters use horizontal polarisation whilst most smaller 'relay' transmitters use vertical polarisation. It is nothing at all to do with who the service provider is but more to do with available frequencies and preventing interference between signals on similar frequencies. In general, vertically and horizontally polarised signals do not regularly interefere with each other.
When considering purely local transmissions aimed at a specific area only, such as Southampton for example, use of the vertical polarisation allows tighter control of the area served and hence reduces the chance i=of causing interference to other areas and/or services.

I've got a vertical signal and other than occasional whistling during a windy day it doesn't give me any problems at all.

In fact, I'd argue it's the best signal I've ever had.

Have read recently on a516digital that there are some issues with Freeview on certain set top boxes. I have recently noticed that on my Panasonic freeview recorder DMR-BW780 that recordings go blank for a few seconds during playback. I have only manage to test this on bbc1 HD and bbc2 HD channels. I was wondering if anybody else was having similar problems. I will try and call freeview tomorrow to get some more info.

There seems to be something wrong with this map or the predictive feature that generates it. It does not show Mendip, which is actually the only TV transmitter from which I can get an adequate signal.

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.
