I have a Heath SA-2040 KW ant. tuner. I have added a heavy duty ceramic
switch to select dummy load, or 2 outputs, either through tuner or
bypassing tuner. Neat installation. Tuner working excellently. $150.
I need a round coax switch, with the SO-239 connectors coming out the
back. A Waters # 335 or a B&W 375 (newer # CSA6G). Thanks 73
