THE TRANSMISSION GALLERY
|Photos by Mike Smith and Wayne Brewer||Page last updated: 2020-06-21|
|Mike's photos show the site with two masts and just a hint that there may be something strung between them. Wayne has filled in the detail but Ofcom parameters aren't entirely clear as Radio Wales is shown with an antenna height of 36 m and 5 kW as compared with Five Live at 45 m but 0.4 kW. Both services are omnidirectional according to the parameters but given the location and the type of antenna this would seem unlikely?|
|Wayne found the signs on the main gate to be in Welsh only|
|The transmitter building is between the two masts which are oriented along a north east/south west line and very close to the seafront|
On the left we see a Band II yagi which may have formed part of the feed arrangements at some point in the site's history. Pairs of wires in a V-shape can be seen just to the right...
|...these join to a horizontal section which is suspended between and insulated from the two masts...|
|...which are insulated at the base|
The main antenna therefore seems to be a cross between a "T" and "delta" and probably is intended to have maximum radiation south east and north west?
|Further detail of the feed point - everything is held in position by a combination of springs and insulated sections|
|MF sites are now satellite fed as part of new distribution arrangements.|
