[amsat-bb] Antenna switching between 2 radios

I am using HPSDR and SDR Play as my receiver radio, and a Yaesu FT-857 for my transmitter. I am looking for an easy way to switch the VHF and UHF antennas to the appropriate radio. I have found a discussion on automating this process with SatPC32 and a "coaxial transfer switch" but there is no information on what switch to use for this. I don't need this to be automated but I am looking for something better than manually swapping coax cables.
