Mark -
You can do this 2 ways that I can think of. First is a board with relays and an interface to a PC. These are cheap (as low as $15) and readily available. However, you'll need to wire up its terminals to connectors suitable for your antennas. These can be found easily on Amazon and eBay. Second is a remote antenna controller. DX Engineering carries sone, although I know nothing about them. A Google for remote antenna switch will get you bunches of hits. They can be expensive a la DX Engineering.

Two or more antennas 2. Spectrum recordings are set up for two or more times of the day (sunrise and sunset, for example) Are there antenna switches out there that can be switched programmatically from my PC at certain times of the day? The goal is to be able to program spectrum IQ (or even single frequency IQ or audio) recordings at time T using antenna X. Or at the least, the goal would be to be able to remote in to my PC and run a program that would allow me to (a) select which antenna is active, and then (b) start a recording. I can already do (b), but the recording will be using whatever antenna happens to be selected on the mechanical switch (and it's usually the wrong one).
