Picked this up in a odd lot box at a radio auction.
Plug in coils are Potter & Brumfield KRP11AG 120v and KRP11A 115V. Dymo labels on box read Trans and Antta.
Wired into box are 2 octal plugs, a line plug and a coax connector.

Looks like a transmitter to antenna switch box with two relays. Probably for matching when band switching.
