There's nothing unusual about the AH-2b except it's designed around a every substantial
base insulator and mounting.  The antenna is just a long steel(?) tapered rod.  The AH-2

tuner and AH-2b antenna were introduced many years ago, and was a spin-out of ICOM
sales to non-amateur users.  The Japanese language instruction sheets in the early days
showed how to mount the antenna and tuner on water craft and military vehicles.  The
AH-4 works best on the low bands if there is some distributed inductance along the
length of the rod.  Like a wire-wound fiberglass rod.  You should try a Hustler with
a 20-meter coil on 80, 20 and 40 meters with the AH-4.      73    Clete
