The co-ax feeders were very impressive bits of plumbing. The outer was about 5" diamter, the inner more than an inch. I have a U link from the old analogue installation. I'll try to find a photo.
The old output stages (klystrons) were water cooled. The new transmitters use vapour cooling on IOTs https://en.wikipedia.org/wiki/Inductive_output_tube
