"SGC couldn't design their way out of a "Wet Paper Bag" and they
didn't do any of the "Original Design Work" on any of the Autotuner
Products. ANY THAT IS A FACT!"

Ok Bruce, I get it. No need to bust a blood vessel over this. The
SGC radios are known far and wide as being junk. The SGC tuners
however, DO have a good rep, no matter who designed them. But for the
sake of your argument, we'll dismiss SGC as a player in the
coupler/tuner market. Here's ICOM's position on mounting automatic
antenna tuners on sail and powerboats.
