Bob: Of course, after switchover the digital coverage will match the old analogue coverage area.

We keep losing our digital channels this week. Retuning sometimes gets them back, sometimes it dosen't or it will get some back and not others. We have had a new aerial and new amplifier fitted together with a new Panasonic TV. Why is the digital signal from Hannington so erratic for us this week? We live in Basingstoke RG27.

I have looked at the Freeview interference page but this does not seem to be our problem as we lose the digital signal for some channels for hours at a time. At 8:00 this morning we had a full compliment of digital channels, now our first digital channel is 10 ITV3. So we have not digital BBBC1 or BBC2 (which I thought were the strongest digital signal) or ITV2, Channel Four or Channel 5. All seems very odd?!?!

Ann - sorry to come back two weeks later! It's actually Mux 2 and A which use the 64QAM 2/3 mode. This mode requires *more* signal, relative to noise, than the 16QAM 3/4 mode used by multiplexes 1, B, C and D.
ITV and S4C didn't change modes on their multiplexes in 2002, after ITV Digital collapsed and the BBC-led Freeview consortium took over their previous multiplexes. The BBC, operating Mux 1 and B, and Crown Castle, who got Mux C and D, were encouraged to change mode to improve coverage and reliability, at the cost of losing one-quarter of the capacity.
For most people, multiplexes 2 and A therefore are the least reliable, but it does depend on the clashes between channels. As you say, you're very close to Horndean. While it uses a different polarization - vertical rather than horizontal - the aerial does still pick up some signal from the other polarization. The spec sheet may refer to 'cross-polar rejection', which is the difference between the amount of signal picked up when the aerial matches the transmission, and when it doesn't. Horndean's not very powerful but you're only half a mile away, whereas you're nearly 15 miles from Midhurst and there are two hills in the way, completely blocking line-of-sight. Horndean frequencies clash with Midhurst multiplex 1, A and C. After switchover Horndean multiplexes will clash with Midhurst multiplex A and D.
Digital UK's predictor algorithm allows for 16 dB of cross-polar rejection, and 16 dB of rejection of signals from another direction, but oddly caps the total contribution from both sources at 16 dB. Most real aerials have at least 20 dB of cross-polar rejection and also have good directional response, so DUK's prediction may turn out to be too pessimistic.

We moved to Andover Hampshire in June of last year and since we have been in this house, we have had interference problems on all channels (digital and analagoue). We receive the signal from the Hannington transmitter.
Following many complaints to the BBC (who are now responsible for the reporting of Interference problems), OfCom attended site and did some signal measurements from our aerial and the results were extremely poor. The engineer also took independant measurements outside in the road using his own aerial and there was very little change - still bad.
His accessment was that because the signal is so bad, any nearby bit of electrical equipment (Boiler, room thermostat etc) could cause this interference.
What possible course of action can be taken to get this signal problem resolved and whom should I approach? The BBC? Arqiva? I object strongly to having to pay for a TV license when we are unable to watch any programme without losing the picture and sound mid-way through for 30 seconds or more.

Sue B,
Hook is notoriously bad for a digital signal at the moment.
The majority of residents have had high gain aerials fitted for the London transmitter as it tends to offer stronger digital reception. From Hannington the signal is likely to vary more as it is so borderline.
Either way there is no guarantee of trouble free reception until March 2012 - unless you change to Freesat.

GStrickland: looking at your location, I'd say the problem is that the line-of-sight signal path from the transmitter is very, very close to the hills. It may be obstructed at a couple of points. There's a strong chance of getting reflections that weaken the signal.
However, Digital UK's predictor does predict very good results both now and after switchover, so there could be another issue, some form of electrical interference from streetlighting or neighbouring houses. You're pretty close to the transmitter so even a reduced signal should be relatively strong.
There is absolutely nothing you can do if the issue is that the signal is being attenuated too much by the terrain and/or by reflections from terrain or structures. If it's nearby structures you could try raising the aerial. The estimated coverage level of terrestrial transmission is 98.5% of the population; the other 1.5% have to make their own arrangements. As I say, though, DUK (which is a front for the broadcasters) reckon that you are covered.
The man from Ofcom should have investigated other possible sources of interference. I believe they can require the owners of any interfering equipment to get it fixed.
