Aerialman:

Some parts of Telford cannot receive acceptable signals from either Sutton Coldfield, Winter Hill or the Wrekin - hence the request for a post code so we can identify the reception conditions at the enquirer's actual location. Onl;y with that information is it possible to give meaningful advice rather than if's and but's and maybe's that are not particularly helpful to non-technical viewers. #

Dover (Kent, England) Full Freeview transmitter

Chris:

You could consider obtaining a satellite receiver and having a dish installed. Then you would get True Crime and several other services.

Not arrogance, merely trying to be as helpful as possible to someone asking a sensible question.

Ellie:

It could be as others have reported similar disturbances to their reception. Do not try to retune your TV though as you are likley to lose more channels that way.

There is also the issue about terrain. Some of the hills around Wellington, Somerset may make reception from one or other of the main transmitters somewhat difficult. A Post Code will allow examination of the terrain and reception predictions for a particular area. These would show as the blue boxes below ypur submission, like those below this for my location.

Michael Bauer:

No, an indoor aerial will not receive much signal and certainly not enough for satisfactory viewing. Depending on exactly where in Ramsbury your are, you 'may' be able to use an aerial mounted in your loft, but they can be severely affected by snow on the roof (whether tiles or thatch) and signal received will not be as strong as with an outdoor aerial, which is highly recommended. Do not fall for the scam of a 'digital aerial' as all UHF TV aerials are suitable for receiving Freeview. I would suggest a good log-periodic aerial as that will be suitable for the signals currently transmitted and those predicted in the future.

From the Freeview Map shown in the blue box below your posting, you are right on the edge of the area covered by the Marlborough Freeview Light transmitter so signal strengths could be variable and an indoor aerial is unlikely to work well. The alternative transmitter, at Hannington, is a full Freeview service and is shown as giving variable to poor reception anyway, so is not recommended.

Mr Reeden:

MikeB was asking for what strength your signals are on the different muxes, not the quality. It is the actual signal strength that can be the cause of your query, so that's the information needed, please?

Andrew Tegala:

If you look at the 'digitaluk trade' box below your posting, you will see that the signals from Crystal Palace on channels 22, 25 and 28 are listed as being variable. So it would be helpful if you could give an indication of the signal strengths reported (not the quality) as you could either have too much signal, possibly due to the booster, or maybe too little signal possibly due to the reported variable nature of reception of some signals.

It would also be useful to know what type of aerial you have in your loft and where it is aimed. For Crystal Palace you need either a Group A or log-periodic aerial and for Hannington you need a Group B or log-periodic. An aerial for group B aerial would not give reliable reception of the muxes on lower channel numbers from Crystal Palace. If the aerial is pointed at Hannington, bearing of 247 degrees, then the Crystal Palace signals are being received by that back of the aerial, which is never reliable. Crystal Palace bearing is 88 degrees at your location.

Further comments possible depending on your response.

Chris:

What you are able to receive via your ex-Sky box is not Freeview but Freesat! Sutble difference I know but for clarity sake we should use the more accurate terminology.

Like jb38, I suspect ypu were mis-informed about retaining the ability to record or watch existing recordings. My brother used to work for the company designing the Sky boxes and he confirmed that the design spec calls for the ability to record or view recordings is controlled via the viewing card and when the subscription is terminated that is instructed to lock the record facility.

Tony:

Generally the multiplex used on main transmitters for ITV is the same output power as that for the BBC channels, it is normally only the DVB-T2 multiplexes (used for HD mainly) that may be a lower power output - but not always. The 'Freeview Light' transmitters do not transmit all the channels, that being decided by the commercial broadcasters on the basis of how many viewers they might reach and hence determines the potential income from advertising.

The output power of any multiplex is a matter for the operator, Arqiva, in conjunction with the broadcasters and Ofcom.
