The Type 13 was designed during WWII and was introduced into service just before the end of the war. When RAF Saxa Vord was being planned it was envisaged that there would be up to 3 Type 13 Heightfinders and 3 separate sites were actually constructed to mount these radars. In the event only one Type 13 was installed.
It had a limited range compared to the Type 80 and was unable to operate in high winds but it was it was to be the only Height Finder for more than 20 years of Saxas operations. The Type 13 at Saxa was never to get a radome which made its wind limitations a frequent problem. The RAF must have purchased significant numbers of the various versions of this radar so that, unlike with some of the other radar equipment, spares seemed to be available fairly quickly. This was fortuitous as the Type 13 was damaged quite often by the elements.
The final photos show the Type 13 at the end of its operational life just before decommissioning. These pictures were taken just after the radar was damaged by high winds on on 16 Sep 78.
