P de havilland:
We need a full post code so that we can examine the transmission and reception conditions at your specific locality.
There are no problems reported for the Redruth transmitter at present, so you may have a fault with your aerial or equipment.

Chris.SE & StevensOnln1:
I have taken the liberty to email Arqiva about the situation with Crystal Palace and Hannington both broadcasting on Channel 29 (538,00 MHz) and as the service areas overlap considerably, many viewers are unable to watch either or both of the That's TV services carried on that multiplex.
I await a response and will communicate what they say, if anything.

Christopher Webster:
I'm afraid you've missed the point. The changes planned will mean that COM7 and COM8 will no longer be needed as other multiplexes are transferred to DVB-T2 coding which will provide more channels than currently available. So the COM7&8 services will transfer to new multiplexes and not be 'lost'.
As you already have a wide band aerial, you will not need to change that either as it already covers all the frequencies available for TV broadcasts now and in the foreseeable future.
Satellites cannot provide services to any conventional mobile phones. You need a specialised type of phone to get any signals from the communications satellites. 'Normal' phones use ground based transmitters all around the country and serve most of the populated areas but less so in the more rural areas.
So you will not lose anything and not have to obtain any new equipment if you already have DVB-T2 equipment for Freeview HD. All you will need to do is a proper retune. The cost to you is zero. Then you can enjoy all the available programmes that you currently enjoy and perhaps more as new services start.

Chadi:
The channel has moved to different frequencies. Please provide a full post code so we can look up which is your local transmitter and hence find which channel it is broadcast on, if it is available now in your area.

Chris SE:
Usual initial response claiming that it is Ofcom's responsibility but at least they have passed my comment forward to their technical planning team. So I await their reaction.

Mrs Anderson-Archbold:
To let us help you we need a full post code for your location. There are over 1000 transmitters so that post code will help us determine which serves your location and hence if there are any reception or transmission problems.

Roger:
please can you give us your full post code so that we can examine the reception and transmission conditions at your location. That the transmitter aerial is 'hidden' by a hill may be a clue, but examining the conditions may help.

Phil:
Further to that said by StevensOnln1, I concur that 'indoor' aerials are not at all effective unless you are very close to a powerful transmitter. Years of TV field servicing experience suggests they are never a good solution.
One alternative is to have an active splitter added into your existing aerial signal feed and an additional coaxial cable run from that to your Summer House, bearing in mind that aerial cables are not designed to be suspended or buried. So if it crosses 'open space' you will need either supporting wires to 'hang' it from or sealed circular trunking below ground for it to fed through. Or else have a new aerial fitted where it can receive a good and stable signal.

Mr Michael D Archer:
I am confused by your query. DAB reception does not use, or should not, your TV aerial as DAB services ae=re on completely different frequencies. But are you meaning that reception of Radio services via Freeview is poor? I also wonder whether that particular radio service is carried on Freeview.

Nicholas:
CRTs never explode! They always implode due to the vacuum inside. We took high speed cinema film of all our experiments at Philips and they ALL showed the tube imploding and none exploding. Simple physics really.
When we did the tests some of us were directly in front of the CRT being tested - but protected by a toughened glass screen and metal enclosure. So yes, we were in the firing line. The test involved the CRT being hit by a mandrel supported inside a test cabinet and being hit by a 5kg weight dropped from 35 feet above the cabinet.
You clearly do not understand the lengths TV manufacturers went took to ensure viewers were safe from any implosions of the CRT. The glass does expand outwards AFTER the implosion, as I stated earlier.
I totally concur with what M-B states.
