The symbol shows the location of the Hannington (Hampshire, England) transmitter which serves 470,000 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 Hannington (Hampshire, England) mast?

Andy: Yes, there are engineering works, but they relate to the aerial that is currently providing analogue signals. It will be the digital antenna after switchover. There may be occasional periods of low power on digital if they have to climb past the digital antennas, which are below the main antenna at the top of the mast, but I believe all the necessary installation and cable connection has been done.

The old antenna was replaced at the end of last year and I believe it's now back in service, though my aerial points to Crystal Palace so I can't be sure.

I've run a prediction for Watertower Way (RG24 9RF), which appears to be on the estate. It's relatively poor - no coverage predicted for multiplexes B C or D, variable for multiplexes 1 2 and A. However, about 500 metres away on Barton Place (RG24 9JS), it gives a prediction of good reception. The predictor may be using the permitted radiation pattern rather than the actual. Your postcode, RG24 9TG, is about another 500 metres to the south-east, and here there's no prediction for multiplex 1, 2, C or D, and very poor for multiplexes A and B. The predictions do *not* account for any engineering work.

Basically, the problems get worse the closer you are to Guildford, which is the interfering transmitter.

For best results, the aerial should be fitted outside, with lots of clear space around it to reduce reflections from the buildings. The developer may have fitted an aerial in the loft, or a communal system, to reduce the visual impact of the aerials if the site is considered sensitive. If the aerial is in the loft, complain: they just don't work as well as they do outside.

After many months of good reception, we now have intermittent poor signal quality on BBC and ITV muxes which is forcing us to watch on analogue. Interestingly, the quality for the England 6 Nations match last weekend improved 10 mins prior to the start and reverted to poor quality 10 minutes afterwards. How frequently are they turning down the power and why is it so bad in the evenings anfd after dark?

Tony: There were no planned power reductions during the last week.

As I understand it, the engineers work to ordinary working hours and if work is required on the mast itself (rather than the transmitter equipment at ground level) it must be carried out during daylight. The exceptions seem to be power testing and the actual switchover itself which are carried out between midnight and 6am.

Problems experienced in evenings and after dark are more usually to do with the changes in how signals reflect off different layers in the atmosphere, as they cool off. On clear nights, there can be an 'inversion', cool layers nearer the ground which cause signals to reflect. This is termed 'tropospheric enhancement'. For more information see http://www.dxinfocentre.com/propagation/tr-modes.htm. (That site is written from the perspective of *wanting* distant transmissions - here, you don't want them because they cause interference.)

Hook is in the sector of Hannington's analogue coverage area that is not intended to be covered by its digital transmissions. Hannington's current low power digital transmissions use the same frequencies as the Guildford transmitter's analogue transmissions which - until switchover - take priority. Digital UK show no prediction for your postcode. It is not expected to work with any reliability at present.

The aim is for post-switchover digital transmissions to cover the same area as pre-switchover analogue transmissions, and Hannington should give you a good service from the middle of next year. If you can't wait that long, consider using Crystal Palace, satellite, or cable. (RG47SH)

Hi Tony. I, too, point at Hannington from Hook. My post elsewhere describes recent problems with losing everything on MUX2 on three out of four TV tuners unless I connect them to PVR (Smartbox) tuners. I've tried elimination of household interference, etc. without effect Short term answer for you may be to acquire a decent PVR (perhaps borrow friends' first to see what might work). Else we await 2012 or seek Crystal Palace.

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.
