Roger Scott: Forgot to add, that if you are getting a significant signal on Ch.29 from your Hannington aerial (the mux aimed at Reading) then this will be a much more difficult issue to resolve at this time, also after March 21st this year COM7&8 at Crystal Palace move to Ch.55&56. These muxes at Hannington move to Ch.55&56 on April 18th. So it's possible that your current diplexer will give you a working solution after that date.

Roger Scott: OOOps, sorry, my last statement is incorrect as the Local Muxes are also moving channel.
Crystal Palace is moving from Ch.29 to Ch.35 on March 21st (with apparently some increase in power - not sure of detail), and Hannington is moving from Ch.51 to Ch.32 on April 18th and the other local Mux on Ch.29 is moving to Ch.34 on that date.
So a standard diplexer is not going to provide a solution, whereas a low loss splitter might.
Also with COMs 7&8 on Ch.55&56 from both transmitters after that date, though they are SFNs you hopefully won't have a problem, but you definitely shouldn't if your Crystal Palace aerial is a Group A aerial and so won't get Chs.55&56 with any decent strength.

Chris. Thank you very much for this information. It seems that I won't really know the outcome until these other frequency changes are done in the spring. For the moment I have refitted the diplexer so am back with the BBC4HD signal problem but I can use my Sky box to watch this channel. My Crystal Palace aerial is definitely an A group and the Hannington aerial is possibly a B group as in the anologue days Channel 5 on channel 66 always had a snowy picture. It would seem with the frequency changes ideally the aerials should be wide band. I image that there are similar frequency changes in other regions as well in preparation of loosing the 700 MHz band

Roger Scott:

Instead of using a diplexer feeding two aerials into one TV, you may well do better to have a coaxial switch that is fed by both aerials. You can then switch between Hannington and Crystal Palace without getting any problems of interference between the signals. Plus there would be less signal loss.

When I live in Swindon, I used one so I could get both Mendip and Oxford signals and watch Central South as well as BBC West. It worked very well for me so it should be ideal for you, certainly better than using a diplexer with its losses and risk of serious interference on some multiplexes that share the same channel.

MikeP. Thanks for that suggestion which does make sense. The only problem I have is that the aerial feeds go into the loft where the diplexer is and from there I have one coax feeding down to the TV. Obviously it's not practical to go into the loft every time I want to change regions so I will need to fit an additional coax from the loft to the TV so that I can fit the change over switch by the TV

The problem I have though is that both aerial feeds go into the loft where the diplexer is and from there I have one coax going down to the TV. Obviously it's not practical to go into the loft every time I want to change regions so I would need to run another coax from the loft to the TV so that the change over switch is near the tv

Help! I am in the RG31 post code area and receive signal from Hannington transmitter. Since the beginning of February I have been having problems with low signal quality. I have been monitoring this on my TV diagnostics facility now for 10 days. I noticed that the problem started at around 16:30 each day, including Saturday and Sunday. Before 16:30 signal quality is reliably at 100%. After 16:30, signal quality plummets to below 10% and regularly below 7%. This situation lasts for 70-75 minutes, when the signal quality becomes 100% again. Note that the signal strength does not drop, at least until the low signal quality causes 'no signal'

It appears that something is switched on at 16:30 and interferes with the Hannington signal. 75 minutes later it is switched off and the interference disappears.

What can I do to identify exactly what is going? I do not believe it is 'induction' interference from other appliances, as I am quite familiar with that.

Keith Farrington: Since it sounds exactly like single source interference, why would you reject that possibility?

In the meantime, at least check all your cables - if they are poorly shielded, etc, then that will make the problem much worse.

Keith Farrington:

As a matter of interest, do you havce a 'smart meter' fitted? Some have been saying they are getting interference from the meter's WiFi system.
