The Skylab Command Van and associated UHF (circular polarization) Command Antenna in early 1973.

In 1973, Skylab was launched from the Kennedy Space Center.
Engineer John Berry and Operator Richard Black manned this transportable van set up in the car park next to the main Honeysuckle operations building.

Inside the van was a huge Klystron, which provided a high powered UHF uplink signal to the orbiting spacecraft. During passes, commands were sent from this van to Skylab.
