The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Oxford (Oxfordshire, England) mast?

Caz: Your blond husband is switching off the booster which is likely to be located adjacent to the aerial. What is referred to as a "booster" is in fact a power supply for a booster which is fitted where the single feed from the aerial splits into two, one to each room. Thus, by turning off the power supply the booster has no power and a booster with no power will give out little or no signal.

Well, good news for you, mine is definitely interference from next door. Does anyone have any ideas on how i can protect against it?

rob: I just have to ask have you had the aerial checked out. I have never heared of interfereance from the next house. If your coax is damaged this could be letting in the interfereance but a good aerial with good coax with sheliding should block it. So call someone out to check what the problem is this website is good for advice but without being at your house no one can give you 100% the answer.

Rob: I'm in Oxfordshire and I had on and off reception with some channels last few weeks too and this week lost a lot of channels including the HD channels. Surely this is just down to the oxford transmitter engineering works this week? That would be why your neighbour also has poor reception. It was obviously not a great signal before which I assume is why they are working on it. Is there any way of finding out the details of the engineering work? (51.6887,-1.2717)

Because of Rob's very different location to you, the suggestion of a 'booster' (better called an aerial amplifier) is not correct. He is only 7 km away from the Oxford transmitter so gets a good strong signal already and it does not need amplifying. If it were then in his location he would have had far worse loss of services because of the signal then being far too strong.

As we do not have any idea of your location, other than it being in Buckinghamshire (with is not a small county), we cannot make any suggestions.

As David Linsay has stated, the item behind your TV set that is connected in the aerial feed cable is a power supply, the amplifier is mounted close to your aerial. The power supply needs to be left powered on to operate the aerial amplifier so your bedroom signals are properly delivered.

Much earlier in the discussion of Rob's problem it was established that it is only affecting one TV connected to his system in the room that is adjacent to the wall which has his neighbours Virgin equipment at the other side. The problem is not present on his other TV sets, so the aerial is fine and not a factor in this particular problem. Likewise, he has tried moving the TV set to the other side of the room successfully, again showing the aerial system is not a culprit.

Thanks Mike P,
Hope the neighbors ring virgin for an engineer like they said they would. I cant see this being anything else than em interference, hoping that the engineer will move the offending source.
could by a new tv but don't really want too and there is no guarantee that the new one wont do the same.

Rob: Have you as yet tried turning your TV around by 90 degrees so as to have it facing end on to the offending wall? the reason for this request being that I suspect that your TV "might" be more susceptible to picking up locally generated EM interference directly into its PCB circuitry if any of the internal earth bonding jumpers used to link the metal screening cans on such as the tuners or any other vulnerable areas have not been tightened up properly, or indeed are missing! and should anything of that nature apply then any interference being picked up in that way is usually highly directional whereby is affected by angles, likewise turning the set around by 90 degrees or so being one way one way of revealing its existence without having the benefit of any test gear being to hand, that being your biggest impediment!

MikeP: that doesn't rule out any problem that having the system checked won't correct , but then again I don't know how to fix a tv I only know about aerials so I stick to advice about aerials.

Hi jb38
yet to turn the tv around, i will have a go today if i get the chance, i thought that the shielding on the tv would have been good it being Sony. However this may be the first time it hAs been near any type of strong EMI so may have been faulty all along.
Is there any check i can do inside the TV?

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.
