[Icom] AH-4 tuner

Mon, 31 Mar 2003 00:45:54 -0500

Robert,
   If my memory is correct, the AH4 is designed to sit at the base of the
antenna.   It's not a PL259>PL259, but PL259>ant base.   For that reason,
it specifies what bands will be tuned by a whip over so many feet long.  
I have the AH3, love it, just doesn't cover 6 meters.  Most of my mobile
work is with my work truck, so I'm out during the day.   A 10 ft whip
works wonders on 10-30 meters.   I've had several different antennas,
like this for ease with the 706Mk2.   Just hit the TUNE button, and
you're ready to go.
