Actually Willis, there is no additional tuner. Just the motor in the antenna
and a single base matching coil. I have put in a 15 turn airdux coil and use
taps to set the best for 80 and up. Works for me.
Pictures on on file at several elecraft/antenna/mobile/HI-Q/ etc blogs.
Anything in particular and I will send it direct.

I use the HiQ 4-80 with a 2' mast extender mounted on the back bumper of a
F150. At the base of the antenna I have a hb box of six relays to switch in the
appropriate capacitors to match the feed point impeadance and I use the
Ameritron SDC-102 memory controller that does a good job of going to the saved
locations but I usually have to give it a "bump" or two on 60, 80, or 160 (with
aux coil I can add if I have to get on that band).
As this system is "almost" seamless, and as someone else mentioned. I still
stop to change bands to keep it safe.
The old ARRL mobile manual is still pretty good read on this subject.

Interesting comments Mel.
I have purchased a Little Tarheel and installed it on my
vehicle, but I have not got around to doing anything with
it. I have a MFJ tuner that looks like it will work as
well as the one you use. Are you using a Coax switch? I
would be interested in your pictures if you have them on
line. I also have a MFJ tuner that I have not installed as
yet, but it looks like if you installed the tuner so that it
is in line with the anslyzer or the rig when you have a coax
switch installed you could use auto tune and then see what
you have as well. Willis 'Cookie' Cooke,

While I never tune while driving, I got rid of
the autotuners for the HI-Q 5-160 antenna and installed a
switch to allow me to transfer the antenna to a FG-01
analyzer. So when I need to move frequency, I pull over
stop, switch to the analyzer and tune the antenna. Simple
and fool proof. Legal too. Pictures on file.

I have
a Little Tarheel screwdriver antenna on the 4Runner. It
works well on 21MHz and higher, and less well
as you go down in
frequency. When parked, I
try to add an external counterpose
clipped
to the ground side of the antenna mount, which seems to
help on 40M. I really think you want your
counterpose to be on
the order of 1/4 wave
long, and the 4Runner isn't 10 meters long.
I do remember doing search and
pounce in the California QSO
party on 80M.
As I tuned up the band and found a new station, I
had to re-turn the antenna, which I did while
giving my call.
Everyone who answered said
something along the line of, "You're
down in the noise, but we'll make it
work." I thank them.
