I have done side by side comparison of a 102" whip tuned by an AH-4
equivalent vs. a resonant style antenna such as the Hustler series. On
40m, There was a repeatable 1 "S"unit difference in rx signal and tx signal
strength. I did not have the chance to check it on other bands, but the
difference would probably decrease as you got closer to 10m, and increase as
you went to 75/80m

Bottom line is that if you want/need performance in a mobile environ, use
some sort of resonant antenna, especially on the lower bands. However, a
102" whip will do for convenience. Or you can split the difference and get
a screw-driver style antenna.

Try Radio Shack for the 102" whip.. they still sell em

Oh, and for kicks, you might want to chuckle at my insanity while
looking at a similar setup at http://www.csotbs.org/ai8w/TruckPics

I sold that truck, and haven't had a chance to reconstruct that system
on the new truck yet, but it's coming.

Re 20 meter hamstick and AH-4:

Do you mean you are using an AH-4 to tune the 20 m hamstick
to other bands? If so, to which bands and what kind of SWR's?

I have used it on 40 meters successfully and on 15 and 10. The SWR is
perfect. The efficiency of the system is not so good. I can do the
same thing with my Webster BandSpanner. My biggest problem is being
mobile when there is a band opening. Havn't found that many on 15 & 10
recently....at least when I have been in the car.

With the AH-4, it really doesn't matter what I put back on the antenna
mount. It will find he L/C combination and match it to the radio
(within reason of course...obviously can't use a 1/4 wave UHF spike on
40 meters). I have been looking around for a 102" CB whip. That would
work as well as anything.
