Previously, I ran one RF cable from the SDR to the antennas. A splitter was on the mast, so each antenna could connect from one main able feed. But this means that each antenna interferes with the other antenna. Ideally, there is a cable run for each antenna, and each antenna has its own SDR.

This would support UHF and VHF antennas. So observations can be scheduled for either. Both can be used simultaneously only if the satellite in the observation is transmitting both UHF and VHF.

Right now, just UHF is being used, although there is a VHF antenna mounted.
