Jeff Meagor: The three commercial (COM) multiplexes from Beacon Hill are at half power with respect to the Public Service Broadcaster (PSB) ones, they are 10kW and 20kW respectively. The power of the PSBs is so as to provide the same coverage as the old analogue ones did. My point being that the COMs are restricted as opposed to the PSBs having extra strength. This could be to protect against interference with other transmitters using the same channels such as Plympton.

The other thing about Beacon Hill is that the UHF channels (frequencies) it used to use and those which it uses now. For analogue it was Group C/D (Ch48-68) only and if you haven't had the aerial changed from a C/D, then it could be the problem. Whilst the PSBs are C/D channels, the two COMs SDN and ArqA are a bit lower down in Group B (Ch35-53).

For information on aerial groups, see here:

Aerials, TV Aerial and Digital Aerial

For a list of services carried by each multiplex, see here:

DTG :: DTT Services by Multiplex


Are the services that you are trouble with in the COM multiplexes which are on lower power? Are the BBC and ITV1/C4 ones OK?

Hi there...

Would you be able to advise on optimum channels I could select for inputing a video input from CCTV via a Modulator on a domestic TV aerial system in order that I avoid conflicts with existing channels, in this particular case in PL9 8JJ ?

Any info you could give or direct me to would be greatfully recieved...

Kind regards

Simon Waring: Avoid using any channels under 30 and anything between 41 - 63, this covering all the four transmitting stations that could possibly affect the analogue picture quality from the CCTV camera.

Simon Waring: Just a small correction to the second range mentioned as I just noticed that in 2013 one of the muxes used by Ivybridge drops to Ch40, this now making the the "either on or between" channel ranges to avoid being 39 - 62.

I live in modern flats with a communal aerial (post code PL1 2BD), I have a signal booster and use a Humax FoxT2 HD box. I have poor reception on BBCA and ARQA multiplexes. The picture quality is often unwatchable. I have auto tuned the box several times without any improvement. Can you suggest anything I could do?

Thanks,

Rich Reed: You are indicated as being able to have good reception from the Plympton transmitter at roughly 4 miles away, and so you should ensure that your Humax is receiving that station and not Caradon Hill, the way to check being to carry out a signal check on BBC1 and mux channel number 54 should be indicated along with the signal strength / quality, if though its 28 then thats Caradon.

Do likewise on ArqA (11-Pick TV) and in that case mux Ch45 should be seen whereas 24 if Caradon.

You should also try a test without using the booster and giving an update on the results of your findings, as although Plympton is predicted as being by far the best bet for reception some local impediment to its reception might well be applying which will not show up on the predictor.
