Newtronics (Hustler) have been making center-loaded antennas for 50 years. Their smaller ones have about a 22" shaft and similar sized whip, but if you use the large resonators, you can build one with either a 22" or a 54" shaft.

I am currently using the Hustler Q27 on a volvo and it works great, maybe the best receiving antenna Ive used. The shaft is 31", the coil is 6", and the stinger is 18" so overall height just over 4.5 feet and stinger is held in place with an adjustable screw, not the cheap little set screw like on a Wilson 2000, so its really easy to tune swr.

That one hustler with the center barrel froze up on me at -20 I'm thinking thanks but no thanks. 22 inch shaft

Im guessing at -20f almost any brand antenna is prone to freezing, where were you Fargo?

Shut down at the Flying J or Pilot because the Sisters were shut down , am I right.

I've never known of freezing to present a problem with anything except motorized screwdriver antennas, but I suppose if moisture condensed inside the coil it could be a problem with any antenna that has a covered coil.

Just stayed the night at the hook when it happened... I stick with steel or should i say aluminum antennas and spray it with WD 40 and I have no issues...

TECHNICALLY someone who breaks a law IS an "outlaw" since the word actually means outside the law. But we as a society tend to assign
degrees of "outlaw-ness" depending on our opinion of the severity of the violation. We also tend to excuse our OWN transgressions when (and because) it suits our own purposes.

Drivers use amplifiers for a number of reasons.
1) because there is a perception that *I* need it to get over the noise
and hash.

2) because it makes me feel powerful if I can walk over another station.

3) because it makes me "big and bad"-----even validates the reputation
of the trucking industry and its drivers as "cowboys", rebels or, yes,
even outlaws!

But what DOES the use of splattering amplifiers actually accomplish in the
REAL world? WHY are they illegal to start with? Let's answer the second question first.
a. they are illegal because they are actually dangerous to the user
and the people around them.

b. they expose the users to harmful radio frequency energy that has
been shown to heat the body's cells and alter their structure.

c. they can interrupt one's reproductive cycle (ability).

d. CB operators have NO training as to how to install, when, how, or
why to use additional power. For example, licensed amateur radio
operators must execute and have on file in their station records a
survey (using specific formulas) as to the effects of RF power on
themselves. This includes distance to the antenna from the oper-
ating position, the amount of power being used, and the height of
the antenna.

The FIRST question relates the primary reason for NOT using amplifiers:
interference to other users. How many drivers have heard WAAAAY over-modulated, WAAAAAY over-powered trucks on the CB talking to the next truck ahead? How much power does it TAKE to talk to a truck 30 feet away? HUH? C'mon, ya gotta admit it's kind STOOPID, right? All this extra AND UNNECESSARY power does only ONE thing: mess up someone else who is trying to do his job!!! "BIG" power only increases the amount of noise and hash encountered (and what all drivers complain about)! IF (and I know it's not gonna happen, btw) there were NO amplifiers, all drivers used 4 watts, you'd be astonished at how WELL you could talk with that level of power! The noise would be MUCH less, people could talk for 20-30 miles (with a bit of courtesy and better utilization of the channels). When you've got people trying to work "skip" (also illegal for the same reasons--interference) with over-powered, over-modulated, clipped and snipped, illegal radios, it just compounds the problem.

CB amplifiers are NOT very well built or filtered. They generate harmonic signals, Lord knows WHERE all, and other radio services (including the amateur service) hear muffled noises, scrapes, and mysterious sounds coming from their radios. If "sniffed" out by tuning up or down the bands, you'll find some CBer with a modified, amplified radio sending out muffled, unintelligible (or un-intelligent) signals from DC to daylight. Harmonics are generated at the primary, secondary, tri-level (and so on) which causes that ugly word again: INTERFERENCE to other services; not just to other CBers. CBers don't KNOW that, and likely don't care since, to many of them, the interruption of communications, is a badge of "merit" because it validates their small, unimportant world and makes them (in their own minds) IM-PORTANT!!!! They don't HAVE to learn anything about their operations. They aren't tested or anything, so they don't KNOW that they are doing. Anybody can operate an appliance, and, unfortunately, is what a CB is. Yet that so-called "radio service" causes more grief than all other radio services COMBINED, and I lay that not on CBers, but squarely at the feet of the FCC that abdicated its responsibilities in the '80's. However, because of the "creeping" theft of radio spectrum BY CB operators, their "extree channels", their splattering amplifiers, the Feds are now compelled to act!!!!!

POWER is not the answer to effective communications! IN fact, other than creating interference, it is actually less a factor than CB operators think in making their OWN communications better. For example, CBers think that if they "double" their power, it will make a whopping difference in their signals! IT DOES NO SUCH THING!!!! In fact, increasing power from 4 to 8 watts will do absolutely N O T H I N G to the perceived signal strength at the receiving station! Power (the perceived loudness of a given signal) is measured in DECIBELS. IN ORDER FOR A SIGNAL TO BE DETECTED AS LOUDER AT THE OTHER END, A SIGNAL STRENGTH MUST BE INCREASED BY 4 TIMES ITS ORIGINAL POWER IN ORDER TO BE DETECTED BY THE HUMAN EAR. That means that a 4 watt output would have to be increased to 16 watts to affect the 'loudness" at the other end by one additional S unit! The 16 watts then must be increased to 64 watts for 2 S inits! Then you have to go to 256 watts to get a
increase of 3 S-units. (6 Db= ONE S-unit). Now you've gotta go to over 1,000 watts for 4 S-units!!!! Now look what's happening! The amount of "watts" required to achieve the addition S-units actually produces LESS "return" for the amount of signal produced! You are now running 1,024 watts for a measly 4 S-units! ! But................untrained people think
they are really doing something when they are causing problems for themselves and OTHER people.

That's why they use amplifiers: simple ignorance of the facts!!!
