Rediffusion equipment around Canterbury. Most of this is their public cable TV system, but there are also some pictures here of the University of Kent's internal TV/audio distribution system which used Rediffusion equipment.
I've put the raw photos here for others to reuse under the Creative Commons license below. For some context and more details about Rediffusion, see my Rediffusion in Canterbury article.
