The symbol shows the location of the Long Mountain (Powys, Wales) transmitter which serves 9,500 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Long Mountain (Powys, Wales) mast?

Is the transmitter output the same in all directions?

Friday's failure had nothing to do to with the method of transmission, but I don't recall such a long outage. I thought it was meant to be covered by backup generators? But this is a separate issue to the one of its unreliability post-DSO.

A conspiracy, Briantist?
I don't believe Lee Harvey Oswald shot the transmitter.
But it is unequivocally the case that the government decided that digital TV was the (only) way forward; and it is also certainly the case that if I wanted to watch TV, post switchover, then I HAD to buy digital equipment.
If there is any part of that you think is inaccurate, do feel free to rip it to shreds.

john bayliss: Well, there is the tiny matter that the digital coverage areas match exactly the analogue ones.
If you had an analogue alternative, you now have an identical digital one.

Richard Jones: The main transmitters have full power backup systems, but on the relay transmitters, no additional power backup systems have been installed. If there wasn't a generator for analogue, there won't be one now.

Long Mountain's a main transmitter, not a relay.

Richard Jones - Long Mountain may be line fed and an 'island' site with dependents but for all organisational purposes it is still a relay of Blaenplwyf much the same as Torosay is organisationally speaking a dependant of Blackhill...

I believe all main transmitters aerials are horizontal polarization and relays are vertical polarization.
Long Mountain is still listed as a vertical polarization.
If they switched polarization then everyone would have to adjust their aerial to get a proper signal.

Mark A.: Also this transmitter only has three multiplexes and is not one of the 81 main Freeview transmitters.

Mark A - That isn't entirely correct some high power relays use HP, Cambret Hill being a good example...

Oswestry
At the risk of hijacking this thread, (Should I start a new one? please advise)
I live in Oswestry, slightly North of the town and approx 500ft ASL. At present I receive good analogue from the Wrekin TX on an old aerial that's been here long before I moved in.
As a welsh speaking Welshman I would very much like to receive BBC Wales etc and have been contemplating buyin a Hi gain aerial to pick up the Long Mountain digital transmissions but reading the above comments I'm thinking that perhaps I'm wasting my time planning in this direction.
Maybe I should wait until the Wrekin fires up to provide me with a decent "English" transmission and buy a suitable new Aerial for that to guarantee good digital reception and try and get the Welsh progs by satellite.
Advice would be appreciated.
Regards
Tom Williams
