MD - I personally have no idea - just quoting Brian!
Rob - try asking a LOCAL TV Aerial man, who should know local issues.

Back up to 59 tv channesl today. Saying that, those 'returning' Mux C ones are frozen images with little signal strength. Perhaps may improve tomorrow as weather gets colder.
No Mux A (SDN) channels yet.
Watch this space.

We have recently lost all MUX C channels (chiefly Dave, Dave Ja Vu and E4+1). I have tried retuning but it makes no difference. It appears to have happened in the last 3 weeks (maybe when I re-tuned on 13th September switchover - which saw the long awaited return of Film4). I live in Cambridge and assume I am accessing the Sandy Heath transmitter. Any ideas? Thanks.

Hi Murray.
Seems your problems almost mirror mine.
Today have lost all of the mux C channels so total of 40 TV channels again.
Looks like we both will have to wait until next April :-(

Is Sandy Heath transmitting horizontal or vertical polarity?
I wish to install a loft antennae as I can't (daren't) climb to the top of my chimney stack where the old (pre 1860's) antennae is.
Can you recommend a suitable antennae for the job?
Lastly I have a dish for receiving Philippine channels what do I need to do to hook it up to receive Freeview? Thank you John Morris

One more question to settle an argument with my nephew. He says that co-ax cable needs renewing every few years but I think as the core wire is copper and well protected this is not the case. What is your opinion please?

John Morris: Sandy transmits on horizontal polarity, and as far as fitting the aerial in the loft it all depends on where you are located in Peterborough, as reception can vary slightly between the North and South sides of the city with many in the North end favouring Waltham, although speaking in general terms a good signal can be received in most areas with the exception of Sandy's Mux Ch67 & Mux Ch48 which are still on low power, this also applies to Mux Ch31 but it is generally received at a far superior level over the other two mentioned.
For a loft aerial, I would recommend that you take advantage of an excellent offer I noticed that's on in Screwfix, the aerial referred to seen on the link and is virtually guaranteed to be perfect for your requirements provided its not positioned facing into a water tank. (this aerial in Argos being £52.00)
By the way on the co-ax issue, there is no real need to change this at all provided water hasn't crept into it nor has it been damaged in any way.
This being the aerial referred to.

JM - like your antique antenna!
If your Filipine dish is pointed in the same direction as "our" satellites you need a Freesat box or old skybox. If it is NOT pointing right you can't get them.

John Morris: The cable insulation is plastic and like all plastics, it deteriorates with exposure to sunlight, and can then let damp in. White insulation tends to be affected worse than black or brown.
Cables should be anchored at frequent intervals, including clips over tiles, so that they cannot move in the wind and rub over the brickwork or tiles, which wears through the insulation.
I'd say you should plan to replace cables about every ten years.

Has Sandy Heath recently reduced power on Mux C in the last few days as I have lost all these channels (Sky News, Dave, E4+1). All other Mux channel bundles are fine.
