Nick: Should you be referring to me then I am still around, but though with this being totally dependant on work commitments and which may at times involve me working over night at short notice should I be required to assist some other engineer, as indeed has recently applied.

Martin: I am inclined to think that the reason your problem is more likely to be caused by the signal reaching you suffering from intermittent periods of being partially obstructed by trees, these being in abundance in your area, and should this apply then a high gain aerial is the last thing you want as its sharper focus would make the situation worse.
However, I wouldn't as yet try altering anything until you verify if others in your "immediate" vicinity (no more than a couple of houses away) are also suffering from the problem as its very likely that they are and so its worth checking.
Further advice dependant on findings.
By the way the Virgin box will not be affected as its a cable device.

Richard Tonkin: If you are thinking on changing your aerial then you do not really have many options except to go for a group E aerial which spans from 35 - 68, Mendips span being 48 - 58 therefore the group E aerial allowing a good safety margin at either end of the band.
However, as you appear to be located in an area of reasonably good line of sight (in the RF sense) to the transmitter then I would just fit something like a Log 40 as that should be perfectly adequate for your requirements.

Anne Wilson: I would suggest that the main reason for the problem you refer to is far more likely to be connected to a deficiency in the aerial distribution system used within the hospital and not necessarily down to the area that the hospital is located in being one that suffers from bad reception, because if it was, then I am sure that numerous complaints to this effect would have been made on not only this site but others, something which I can't honestly say that I have noticed.

Nicola Baker: I was wondering about that! because using Kidlington post office as a test indicates that the Oxford transmitter is located at only about six miles away from you, and which in theory dependant on the aerial system being used, could result in your TV or boxes tuner suffering from the effects of being overloaded by an excessively strong signal and something which is capable of causing all sorts of odd problems.
Should you have any form of booster in line with your aerial then for a test try bypassing it, because once that Oxfords six muxes (inc HD) have been manually tuned in then they cannot change on their own.
Oxford's channels being /
53 - 60 - 57(HD) - 62 -59 - 55

shaun: As the Mendip transmitter is located at just under 5 miles away from you then your problem "might" be caused by an excessively high level of signal being received, this always affecting HD before SD and with in many instances the latter showing no signs of any problems.
Should you have any type of booster fitted then for a test either remove or bypass it.

EL: Yes, many thanks for your report and especially when being accompanied with the P/C location being referred to, as this type of info is exceedingly handy for reference purposes.

Pauline: Its impossible for anyone to advise as to what might have been (and still is) the cause of your problem when you have not given any indication of where you reside, this in the form of a post code or one from somewhere nearby, such as a shop or post office.

shaun: Yes, sorry about that as I had meant to say Winter Hill, everything else said still applies though.
I also realise that work is going on at the Darwen transmitter located @ 4 miles away, but this station is not indicated on the reception predictor as coming into the equation as far as reception at your particular location is concerned hence the reason why I did not mention it.

Karen: Unfortunately what you have said requires a certain amount of clarification, insomuch if new roof aerial has been installed then why are you also using one in the loft? or are you meaning that the loft aerial has been installed purely to be able to watch "freeview" on a second TV thats not connected to the Sky box in the living room?
The other point being, are you able to watch freeview via the roof aerial on the TV that "is" connected into the Sky box as well as being able to view Sky programmes?
But though as your query involves reception then a post code or one from nearby is required such as a shop or a post office, should the latter be near!
