This pair of Motorola WR-137 J-band 5.85-8.20 GHz motorized waveguide spdt automatic transfer switches(5.85-8.20 GHz)are used and in excellent working order. Both were used as our STL for both TV stations.  Dual transmitters fed a single switch which would auto switch if one transmitter lost power maintaining our studio to transmitter links. The following I believe to be the general specifications based on my on internet research as I could not locate the original manuals.
