Ah yes, K6HWL, "Highway Louie".  (His real name was Frank.)  He did 
indeed put a brass toilet ball on the top of his 75 meter mobile antenna 
after he set some overhanging tree branches on fire from the corona 
discharge.  The loading coil was the size of a small trash can.


I ended up with his old Drake L4B linear after he died.  You normally 
don't think to ask if a tube-type KW amplifier has been used mobile! 
The amp was pretty well trashed, but I was able to get it working again.

Jeeze, that's QRP.

My Elmer was a neighbor, Lee, W7UVR.  Before SSB he ran a 4-1000A high-level 
modulated in his mobile.  I can assure you that there weren't any toilet tank 
balls on his antennas.  The need for those is IMHO, an old wives tale.  After 
SSB, the 4-1000 ran as a linear.  There was 5KW of generator and while 
stationary, the mini-beam was blown up to 30' above the roof.  The mobile in 
motion antennas were a pair of whips, with remotely (driver's seat) motor tuned 
vacuum variables and silver-plated edge-wound inductors in the matching networks


The car was a '55 Mercury station wagon with a bored and stroked '56 Lincoln 
engine and a truck rear axle and springs.  There was one extra leaf in the 
spring under the side with the pole pig HV and modulation transformers.


There is some more about him (which is a repeat of what I wrote) under "High 
Power Mobile" at http://www.k0bg.com/yesteryear.html and photos here:

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.

 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

 long, and the 4Runner isn't 10 meters long.
 
 I do remember doing search and

 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

Re: [Elecraft] OT: Mobile operation "bible"

[Edward R Cole]

My only attempt at HF in a mobile was on my old 78 Scout Traveler 
(diesel).  Before heading to AK I had a welder install a big front 
bumper with space for a winch and brush guard for front grill and 
head lights.  Alas, I never bought the winch so had a tool box 
installed in its place.  OK I used the 1-inch steel tubing as a clamp 
support for a Hustler 4BTX which I had the 80m whip option.  It stuck 
up there a ways so was only installed when I was parked.  Worked 
K4USA (I think the call was) from Eagle, AK to the Antarctic via 20m 
and 100w.  The scout was a heavy rig 4500-lbs. and had a nice steel 
frame which probably helped.


Now if you want a challenge install a 4-MHz HF Marine SSB station on 
a fishing boat (typ. 25-35 foot).  The one's with fiberglass hulls 
can be a challenge.  Most Marine HF used either 21-foot or 35-foot 
whips and had a manual tuner (In the old days vs auto-tuner now days) 
attached to something metallic right at the base of the 
antenna.  Usually had a 1-inch mesh ground strap to ground and RG-8 
to the radio.  The manual tuners had a motorized switch to select 
taps in the loading coil and jumpers for the bank of fixed tuning 
caps.  Fortunately only about six to eight channels were programmed 
as one could spend a hour easily trying to find the best combo of tap 
position and capacity.  2182-KHz was the mandatory emergency watch 
frequency and getting a good match was awful. 4125-KHz (4A) was the 
standard in AK for all the fisherman and one could hear them some 
times out to 800 mi at night.  100-125w was standard.


On my last job I installed a Harris 1kW linear to serve as Marine HF 
Base on 4125 and strung a dipole at 40-foot between two Rohn-25 
towers (nice to be a rich oil company!).  They sold them as Satellite 
telephone has largely replaced HF for commercial marine.  Boats still 
have them but little used.


Sorry about reminiscing - the topic reminded me of those days in early 1980's.

Re: [Elecraft] OT: Mobile operation "bible"

[Myron Schaffer]

All, 

The coax length doesn't matter because of the following reasons. Assuming the 
tuner is at the rig, there is a run of any coax to the antenna feed point, and 
you have a fairly high Q low band antenna that can't QSY much. 

With short HF mobile antennas that are high Q the reactance at the feed point 
when you QSY beyond 3:1 or so makes the system very lossy regardless of how low 
a loss or how short of coax is in there. 

The power accepted by the antenna under these conditions goes down the further 
you QSY due to the large reactance leaving the dissipated power to be burned up 
in the coax (and some in the imperfect antenna tuner at the rig) no matter how 
low loss it is or how short it is. You cannot increase the power accepted by 
the antenna unless you bring the feed point back closer to 50-ohms somehow 
through external loading of the antenna. (Even then there are other loss 
factors to consider such as ground loss and radiation resistance).

It's kind of like a "tug of war" between two Qs. The antenna Q and the tuner Q 
with the coax in the middle accepting all the power.

Short loaded antennas are, by their nature, pretty narrow band for 
tuning. When I still ran HF mobile, I found that a rig with an 
auto-tuner was a big help in extending the useful bandwidth of an 
antenna. If, for example, the antenna was resonant on 7075, a tuner 
might match it to the rig from 7000 to 7150 or even higher, whereas 
without the tuner I'd be limited to about half that.

Bearing in mind that in a mobile installation, coax is too short to 
introduce enough loss to matter, so it's merely a matter of making the 
rig's output stage happy (and running at full output).

Re: [Elecraft] OT: Mobile operation "bible"

[WILLIS COOKE via Elecraft]

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.
