Briantist: But as Jim's Aerial's says - "VCRs are often pre-set to channel 36 for their UHF output"
Jim's Aerials - TV Distribution
Also SCART to UHF boxes only output on Channel 36.
UHF Modulator Only £20.42 at TVCables
C'est la vie.

Bill: They shouldn't be using C36 for that, as C36 is a DDR non-TV frequency after switchover it should be avoided.
| link to this comment |
Bill: Digital UK I would imagine, it is in all their industry documentation. For example in http://www.digitaluk.co.u….pdf
"Installers adopting RF bypass filters need to remember that these should be flexible enough to take account of sixteen UHF channels being auctioned off post switchover by Ofcom on behalf of the Government. "

I struggle to receive many ITV and Channel 4 channels on freeview through a rooftop aerial. I've asked my property management company to see if the aerial needs replacing but they insist that it's fine. After September 28th, do you know if the reception in Oxford will improve?
Postcode: OX41GA
Thank you for your help.

I have problems getting the ITV1 multiplex but all the others work OK. I changed the aerial to a new wide band one with slightly higher gain. (19 element Maplin MZ40T) The reception on the other multiplexes has improved but still no ITV1.
Any suggestions?

Gaetan: It appears that the radiation pattern of the new main antenna at the Oxford transmitter is a bit different from the old one, and this could have had an effect on your reception. I believe it is actually more circular than before, and also the old aerial did not actually allow the ERP of 500kW to be reached, which means you could well be getting more signal than originally intended.
If you're using a booster, remove it. If not, try adding an attenuator. If neither of these helps, complain to the property management company - the Master Antenna TV system should be adjusted so that levels on all channels (analogue and each digital multiplex) are within acceptable ranges at each socket provided.
Do other residents in the building have the same problem? If so, that would definitely point to a problem with the system. Do ensure that you keep your mobile phone well away from any TV aerial cables, whether visible or likely locations for them to be buried in the walls, because GSM phone frequencies are very close to the top of the TV band, where Mux 2 lives.
The management company should definitely be arranging for the system to be adjusted on 14 and 28 September, as the levels required for BBC A are going to be quite different from those for Channel 4 analogue (which the high-power BBC A multiplex replaces on C53), and the commercial multiplexes will use frequencies never before used at Oxford.
If the system is not adjusted you may well end up with too much signal after switchover, and/or be unable to get the commercial multiplexes at all, depending on how the MATV system is constructed.
For general advice on communal TV systems, see PARAS - Professional Aerial Riggers Against The Sharks .
The actual prediction at your location is for 99-100% probability of reliable reception, on all multiplexes, both now and after switchover, so unless there are issues not covered by the predictor - trees or large buildings nearby - there is some problem with the system. There are a few large trees there, but it should have been possible to site the aerial somewhere that they wouldn't block the path to the transmitter.

R.Strawson: I would strongly advise against getting an aerial from a high-street retailer or DIY store. They don't know what they're selling. The MZ40T is a 'contract' type: these tend to have very uneven response across the band - the gain on one channel may be very different to that on another, giving strange results.
At your location I would go for a small log-periodic such as the DM Log or Log40 at Online TV FM DAB Aerial sales . You are in a very strong signal area and should have no trouble unless trees block line-of-sight to the transmitter.
If you have a booster, you should remove it. It's very unlikely to be doing anything useful and could easily be overloaded. You may find that you need to use attenuation even with a lower-gain aerial.
I would also check that the cables are in good condition. If they've been up for more than 10 years, replace them. Use 'satellite-grade' cable with copper-braid-over-copper-foil screening, such as Webro type WF100. Ensure that you clip down the cable as it passes over brickwork and tiles - see Satellite, Television, FM, DAB, Aerial, Coaxial Cable, Plugs, Sockets, Connectors & Leads for ensuring it can't move.
Your problem could well be that water has got into the cable, which changes the cable's performance, increasing losses but increasing losses at higher frequencies to a much greater extent than lower ones. Or, the cable run could just be too long - the longer the cable, the more signal is lost, and it's worse at higher frequencies than low ones.

Things here in OX28 have been fine lately. Everything seemed to have settled down to good quality digital television.
Until tonight. ITV1 and C5 have been pixellated to buggery and the sound has been like Norman Collier on acid.
I thought digital was supposed to bring a quality improvement? This is ridiculously poor.

Hi,
I live in the OX5 area (Yarnton) and was experiencing a perfect digital service up until a few months ago at which point we're now unable to receive ITV1,2,4 etc Channel 4, Film4 etc and only intermittently receive Channel 5, Fiver etc.
Any ideas what has been causing this and if we're ever likely to go back to the service we had before?
