Ascent Vehicle Antennas and Dishes

The rendezvous radar will require a deployable boom to be run out from the main bulk of the Ascent Vehicle. This will support a little dish about 1/2 meter in diameter.

We'll want the boom out about 2 meters to move the radar antenna away from the crew -- those are microwave frequencies.

A couple of whip antennas for UHF, stubs about 1/2 meter long, would complete the job. UHF will give us broadcast-quality voice and enough data to monitor the status of the ascent stage. We want redundancy because during its flight the ascent stage has to have good communication with the LTV. These two machines will be discussing their relative trajectories throughout that phase of the flight.
