Comments: Risca is a relay of Wenvoe (via Mynydd Machen)
   

Most people in the town of Risca get excellent signals from the high power Mynydd Machen relay, located on top of Machen Mountain which towers above the town to the west. There are also a great many houses who have an aerial on Mendip, which shines down the valley from the other side of the Bristol Channel.

However there are a few who are unable to get good reception from either, mainly located on the mountain side directly underneath (and therefore shadowed from) Mynydd Machen.

Therefore the Risca relay was built, a low power affair standing on a rise on the opposite side of the valley to Mynydd Machen. Transmissions are from three crossed vertical log periodics and cover an area to the south and west of the site. RBL is from a single vertical log periodic pointing (if somewhat offbeam) at Mynydd Machen.


Looking west, with Mynydd Machen on top of the Mynydd.


Looking towards the service area on the opposite hillside. I particularly like this shot, it's not often
you can capture the TX and RX aerials, the parent transmitter and the service area in one image.


The waterway on the left is the Monmouthshire and Brecon Canal.
