william walsh: The channels broadcast by the Castleberg transmitter are available to the rest of Northern Ireland.

The channels that aren't available from the Castleberg transmitter are the Commercial ones and these aren't broadcast from any small transmitters because the operators don't consider it worth their while. They aren't ever likely to increase their coverage and particularly so for a transmitting station which serves only 1,200 homes.

NOLEEN LOGUE:

Without a full postcode we can't be absolutely certain which transmitter(s) you can/may receive. If it is Castlederg, then there are no fault reports except there's been a lot of "Tropospheric Ducting" around causing interference, see https://www.radioandtvhelp.co.uk/help-guides/television/effect-of-tropospheric-ducting-on-freeview for a simplistic explanation.
The BBC have also been reporting this several times on and off for your transmitter.
It may continue on and off for a day or two more.
