Icom AH-4 mobile users:

I recently installed an AH-4 antenna tuner in my mobile
station, connected to my IC-706Mk2G. I'm using a 9 foot
stainless steel CB whip as my radiating element, fed by
about 2 feet of wire from the tuner to the base of the
whip. What kind of radiating element are you using, and
what kind of success do you have with it on 40m and 75m?
I also have an Outbacker Perth antenna that I've used
for many years, but I got tired of being unable to jump
from band to band easily. I've thought about using the
Outbacker with the AH-4, and just omitting the Wander
Lead and matching transformer connection (in other words,
use the Outbacker in its "raw" 75m state). I'm a bit
concerned that the AH-4 won't handle this on 40m because
the AH-4 manual says to avoid odd multiples of 1/2 wave,
and that would be the case using the 75m antenna on 40m.

Let's hear your thoughts and experiences!

I have run a similar set up with the SGC - the 2 foot bit in the car is a
serious
bad point, to the extent that SGC actually make a "bracket" that enables the
box to be clamped to the outside of the car and the whip is mounted on part of
this bracket,
right up very close to the output terminal - the aerial on these boxes starts
and is very "active" at the output terminal.

You HAVE to understand and appreciate that to make them work at all, if not
particularly spectacularly - they are primarily a "convenience box" over a
"performance box", so do have their place, but are quite a compromise.
