The Ton Pentre relay is located on Mynydd Maendy, (Maendy Mountain) just to the South of Treorchy in the heart of the Rhondda valley. It's stunning location and altitude (375m) affords spectacular views up and down the valley.
The cinder access track to the TX is a bridleway and not a vehicular right of way, however I was lucky in that the local farmer and landowner was there to unlock the gate and gave me permission to drive to the site - which I was quite thankful for as at some points the track is a 1-in-4 slope!
There are two sets of transmitting panels, one pair serving Ton Pentre to the South-East, the other pair serving Cwmparc to the North-West and parts of Treorchy that are shielded from the Rhondda relay by the shape of the valley.
The FM TX aerials are an interesting 'slant' type and are located just below the top platform of the tower. Note there are only three of the apertures used - this is because the fourth would point diectly into the side of the mountain!
The UHF RX trough is on the South-East face of the tower, and relays Wenvoe directly.
The FM RX log periodic is vertically polarised and is on Wenvoe too, but there is another 3-element band II horizontal yagi just above it which seems to be on Ferndale. I don't see the point of this, as it can't be for RBS because Ferndale is also a relay of Wenvoe. Anyone out there know the answer?
mb21: Yes Rob, this will be the RBL receive aerial for R Wales, most likely from Wenallt.
