What Comes in the Box and How It Mounts
The 132203-16: The lockwasher and nut are the bulkhead mounting hardware — you do not need to order them separately. The connector mounts through a panel hole and is secured from the front side with the nut; the right-angle through-hole solder tails then go into the PCB. The shield termination is solder, so the ground connection is made at the board, not through a separate crimp ferrule.
The 12.4 GHz max frequency covers L, S, and C bands, plus most of X-band. For applications under 12.4 GHz, this connector is a clean match.
