Excellent!! No Mux A, C and COMC reception from Sandy Heath again and this time its been going on for 3 weeks now. Just in time to miss the whole of the Tour de France. Don't you just love Freeview? It was all so much better before the great switchover when we only lost one or two channels for a couple of days if the atmospherics were playing up.
Does this mean that I'm going to be without half my channels until the end of August and possibly longer??

John: Basically, no. You should have and always have had and will have 100% reception on all multiplexes from Sandy Heath.
I presume your aerial is on the roof?

Yes...the aerial is still on the roof (new wideband in mid-2009) and all was fine (apart from the occasional weather-related issue) until we approached the switchover when channels started going missing at irregular intervals....always the same Mux's as are missing now. Everything settled down after the switchover until a few weeks ago when we started to lose channels and nothing has returned since. All other reception is perfect but if A, C and COM6 are all on very low power, I'm not really surprised that we aren't getting them. The question is...why are they on such low power and how long is it going to last?

Martin - If you are using Freesat you are on the wrong page here, as you do not receive from Sandy Heath you receive from the sky satellite.
Your weak signal could be that the dish is not pointed exactly right; that the LNB (thing at focus of dish) is old; or that your cabling is damaged.
You could certainly try the new dish, but it might be worth paying an expert to sort it - for his time, knowledge, experience, and testing kit.

neil grainger: You will need to point your aerial to the Sudbury transmitter at that address, as you will (at least by 27th June 2012) get all the services from that transmitter.
You can use a group B, group E or wideband aerial with Sudbury.
You need to mount the aerial on the roof, not in the loft, if you want a reliable service.
