At the bottom of the wooden pole, 2 vertically polarised log periodic rx aerials look over the valley towards the Pontfadog relay. At the top, 2 crossed log periodic tx antenna point either way down the valley.

Not many homes in the village of Glyn Ceiriog use the relay, as there is no line-of-sight to the mast from the bottom of the steep hill. I think they themselves use Pontfadog, from looking at the directions that the aerials on the homes are pointing.
