I created my own A/B switches based on the YU1CF information:
https://antennas-amplifiers.com/symmetrical-high-power-50-144mhz-relay/
It uses cheap relays which are available from a lot of sources.

I really like the Top Ten Devices A/B Station Selectors (Part number
TDS-AB-Selector) as 2x1 coax switches with high isolation between ports for
setting up a Multi transmitter contest station. Unfortunately, it looks
like they are now out of production. If anyone has any they are willing to
sell, please contact me off list at AA4VT dot Dave at Gmail dot com.
