This looks like 3 antennas perhaps of 1/2 or 1/4 wavelength, as they
mention low frequency radar.
In that case, if one does not work, and if they transmit and receive with
the same boom for each frequency, they just have less data (only
reflections for the frequencies that work).

However if it recoils and damages the spacecraft, anything can happen.
I wonder what the exact frequencies are, and if they 'sweep'.
