Which companies have run the Channel 3 services in the Preseli transmitter area
Why are Tx,s radiation paterns with held and not in the public domain??We at Newcastle Emlyn receive our terestial tv from the relay mast at Llandfriog which in turn receives the tv signal from the Perseli mast.It is proposed to site a wind farm at Llandfriog in line between the two masts. This I feel will cause untold tv signal problems for the community.CAN you please comment on this? Thankyou

Owen Hesford: The owner of this website, Brian Butterworth (Briantist), has asked the BBC several times for the radiation patterns. Their most recent response is at Update on transmitter radiation patterns (BBC FOI request) | ukfree.tv - independent free digital TV advice .
For the frequencies used by Llandyfriog, we have actually told the international community that we will be broadcasting on them from Blaenplwyf (near Aberystwyth) at 40 kW. We are using them at Blaenplwyf, but only at 10 kW, so we can reuse them at a number of other sites in west Wales: see UK TV Frequency map - channel C22 (482.0MHz) before switchover map | ukfree.tv - independent free digital TV advice for the map. If Ireland were to officially discover that we weren't really using them to the extent we negotiated for, it might cause problems when renegotiating.
As for your wind farm, Llandyfriog currently uses a single log-periodic antenna to receive the signal from Presely. I would expect that use of trough antennas or arrays of logs, and/or diversity reception, should overcome any reduction of signal level. If all else fails, the data can be delivered to the relay site via fibre-optic cable rather than off-air, although this imposes an additional cost to the broadcasters.
The National Planning Policy Framework says, in section 44, "Local planning authorities [...] should ensure that [...] they have considered the possibility of the construction of new buildings or other structures interfering with broadcast and telecommunications services." The local authority could insist that the wind farm operator pays for any work required to restore broadcasting, if it does cause enough of a problem.
