Caernarfon - not an easy site to photograph. The tower, the structure of which is unusually white-painted, is in the ownership of the local Constabulary, and the tower is sited behind their headquarters. Access is in no way encouraged, and the area is surrounded by private housing which makes getting viewpoints difficult.

The coverage does not include the whole of the area of Caernarfon town. It appears to have been provided to address deficiencies in small well-defined low-lying parts of the town. Most of the area can get satisfactory reception from either Llanddona or Arfon.

Although at first sight quite a simple site, it is in fact not so easy to read from purely external appearances. There are only four aerials on the tower which appear to have anything to do with broadcasting.

These consist of two horizontally-polarised yagi arrays which seem to be pointing at Llanddona: and two vertically-polarised log-periodics, far from coincident, mounted on different tower legs.

A little research in the aareas covered by the two logs suggest there are a few people reliant on the relay in both areas, so despite the phase problems which must occur inbetween we must assume that both are active tx aerials.

William Street and Margaret Street - very low-lying properties in the bottom of the valley of the Cadnant brook, evidently had a whale of a time getting pictures before the relay arrived. Every house sports one or more VP aerials on the relay. In the distance, towers of a different kind - Caernarfon Castle.
