E.f. johnson 250-37 1KW directional coupler, matchbox
Here's an E.F.J. directional coupler needed for Johson Matchboxes with SWR meters. It can be use for wither the 275 or 1KW version. It's in excellent condition and includes the original box and instructions. It can also be used with many SWR meters that use an external coupler. It's rated for 1KW up to 150 MHz.
