Comments: Rhondda is a relay of Wenvoe

Once upon a time, in ye oldene analogue dayes, Rhondda A & Rhondda B were effectively two relay stations in one.

Rhondda A transmitted from two vertically polarised trough aerials while Rhondda B transmitted on separate channels from two crossed pairs of horizontally polarised log periodics. Group A receiving aerials were required for Rhondda A while Group E or wideband aerials were required for Rhondda B.

Since DSO things at Rhondda are somewhat simpler. The same channels are used from both the VP and HP aerials. Oh, and the VP troughs have been replaced by panels.

Reception of Wenvoe is achieved using two trough aerials further down the tower.

Originally a BBC landlord site, BBC 2 entered service on 20th May 1968. BBC 1 & ITV were added on 7th January 1972, with S4C available from the launch on 1st November 1982. Rhondda B entered service in March 1986. DSO was on 3rd and 31st March 2010.

BBC DAB entered service on 15th January 2010.

A VP trough remains, but I wonder if it is still in use?
