Hey Larry,
How about a missle detection radar with waveguide the size of air
conditioning ducts, klystrons changed with an overhead crane, a
capacitor bank for the pfn filling a 10' x 10' x 12' room and an antenna
larger than a football field. We had moon bounce from that one also.

Hmm....It was an airsearch, so had quite a rapid rep rate and narrow pulse
width for good multiplane detection. I don't remember the
specifications...but it would have been quite low. I remember it was in S-
band. Power came from an Amplitron fed by a Magnetron with Thyratron
pulser. The pulse forming network was a cabinet to itself. It was quite
loud in the radar room.
