Ralph, Thanks for your informative reply. You're right, there were
several manufacturers that made these units (Midland, Pace, Numark,
etc.). I did try to hook it up, but the SWR was 1.3:1 (almost the same
as I got with a dummy load), which I thought was too good to be true,
but maybe it was due to the low wattage being used (4 watts). I'll get
some proper cables built and go from there.

Joseph2010-

Ralph is right on the money with his advice. I've had a couple of the
CB-type bridges that worked well on Two Meters.

I think your 1.3:1 measurement may be due to mismatch of the 150 Ohm
resistors in the bridge. But it also could be telling you the truth!
Some dummy loads are not good on Two Meters.

Hooking it up backwards should work the same as forward, except the
switch works backwards.

You normally adjust an antenna for best SWR assuming the meter is
telling the truth. In fact, 1.3:1 is not so bad. If you did not have
that dummy load, you might have adjusted the antenna for a reading of
1:1 and never found out it was not perfect.
