[Elecraft] OT: Mobile operation "bible"

Fri Apr 1 19:15:30 EDT 2016

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.
