Made by Kenwood/Trio for Lafayette.

that takes a single wire
antenna and a ground. I would like to make a simple trimmer to optimize
the 75 feet of random coated wire. The wire is copper, Radio Shack.


I can't tell what it uses for an antenna input (50 ohms, 75 ohms, 300
ohms, broadband, narroband, tracking filters, whatever) so I can't
offer an antenna tuner design. Any idea what's behind the antenna
connector?
