Relay ofWenvoe

The Brecon VHF FM transmitting station in Powys, Wales was originally built by the BBC in 1965[1] as a relay for VHF FM radio. It consists of a pair of 15 m wooden telegraph poles - one carrying the transmitting antennas, and the other carrying receiving aerials pointed at Wenvoe transmitting station near Cardiff. These stand on land at Pencrug Farm, about 244 m above sea level.

The station does not radiate television, and never did. TV for the area comes from a different site at Brecon transmitting station a few km to the east.

Bandplan changes allowed more frequencies in Band II, Radio 1 gained its own frequency and National Radio 4 could be transmitted. About this time, the transmitting aerials were changed to the present configuration, radiating a slant-polarisation signal in a fairly omnidirectional pattern using a Lindenblad Array[2]
