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.
[Ed] At the time that Ray took these pictures, the information available was that Caernarfon was a relay of Llanddona and he assumed that the two horizontally polarised UHF Yagis were the receive aerials. Caernarfon is actually a relay of Arfon and those horizontal Yagis are pointing to the northwest and are therefore not part of the TV relay. Llanddona is to the northeast. Of the two vertically polarised UHF log-peridoics, one is for transmit, the other for receive.
A little research in the areas 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 in between we must assume that both are active Tx aerials. |
