The problem lies in what this would actually achieve.  Those who are causing
the problem are already in violation of law.  If the FCC takes away the 
frequency allocation, what will that achieve?  Will the lawbreakers see it
in their hearts to start following the law?

Doesn't this sound a lot like the gun control argument?

YEARS ago when I picked up my first PLL rig, I found that it was quite 
easy to get on these frequencies; many of my friends and I (hey, I was in 
high school at the time...  :)  )figured out how to get many of our 
radio's to work on these two channels; many of our neighbors worked Ch. 
1-3 or above Ch. 19; so we were able to 'hide' on the band for quite some 
time, and chatter away for hours on end...nobody ever bothered us...
 
Another guy figured out he could get 23a and 23b (which are now Ch. 24 
and Ch. 25 in the US); there was a good deal of activity on those freq's 
as well.

If you've never built an antenna before, I would start with something
reasonably simple, like a vertical dipole.  It's 17' 3'' long with
a split in the middle:

                     |
                     |
                     |   <--- wire, pipe, etc.

                     |
                     |

One thing you can do is get two 102'' whips, a metal strip, and mountings
for the whips.  Put two whips together as shown above, and it works
great.  You may need to do a little length adjusting for best SWR.
I like the Valor whips better than the Radio Shack ones, because
you can adjust the length pretty easily.  I have one of these
babies (spray painted sky-gray), and it's nearly invisible in my
"no antennas" neighborhood.

Of course, be safe, be careful of power lines, don't do this in
a thunderstorm, etc. etc. etc.

I would not recommend building your own mobile antenna unless you
really know what you're doing.  Use a commercial 102'' whip
for best results.

You don't need any ground plane for this antenna.   Get it up reasonably
high, and it will work as well as anything else in the omnidirectional
world.   Once you've tasted success, then try something more complex
like a beam.  I agree that you should get a book like the ones listed
above.  Don't waste your time of designs that won't work.  (I've
done that...)

Has anyone else seen in January's Nuts & Volts Magazine, the ad
for 'SECRET CB'?  It's on page 13.  
 
The ad boasts 40 regular cb channels and 40 channels below cb
and 7 watts output AM.  These are GE units and it says they're
intended for export, and not FCC approved for USA.

My question, does anyone have any information on exactly what
frequencies these units operate on?

By the way, these radios are remanufactured and sell for $139.

Subject: The mystery of  export radios
Organization: New Mexico State University
Date: Thu, 28 Jan 1993 00:49:29 GMT

Okay, it had to be asked.  A great deal of us familiar with CB radio are  
familiar with "export" radios.  For those who don't know the term, and export  
CB is a radio that is factory designed for extra channels and modes beyond that  
allowed in the United States. 

As an example, the Cobra 148 GTL-DX is similar to the regular Cobra 148 GTL,  
except there's a band switch that shifts the operating frequency of the radio  
up and down 455 KHZ from the FCC/CEPT band, FM mode, a "slider" which allows  
the transmit frequency to change slightly, and other features that make it  
illegal to own in the United States, Canada and many other countries.

Supposedly, these radios are intended for some "export" market, but where?   
Most countries listed in the CB FAQ have 40 channel bands, which would make  
these radios illegal to operate in just about every country.  The boxes on many  
of these radios say "Uniden Belguim" or "Dynascan Belgium", but I assume  
Belgium follows the CEPT standards most other European countries follow.  If  
not, it would seem somewhat unlikely that special radios for the Belgian market  
would be made, considering the country's population.  

What's real interesting is that the export radios use the same channel pattern  
as the FCC/ECPT bands, and they use a "high-mid-low" or "A-B-C-D-E" switch to  
change bands.  Why not a channel selector which displays channels above 40?

What market are these radios made for?  It seems most likely that these radios  
were intended for illegal use from the onset.

I think probably most of them can't have an agreement in the whole
world ! "only for export" is the term to say that you are not
allowed to use it in the country of the shop - it doesn't say
that it's allowed anywhere else.

Bands A, B, C, D, E were existing. In the past, they were allowed,
at the minimum in France. Now only the band C seems to be allowed
everywhere in the world for the 27 MHz CB radios.

Ask me if you want the exact frequencies of these 5 bands.

> Why not a channel selector which displays channels above 40?

Because this is standardized. It's like this, I think there is
nothing to understand ! Some bands had 80 channels.

Older PLL CBs built in the late '70s and early 80s can be modified to operate  
on more than 40 channels by changing the programming of the PLL chip.  Usually  
the older PLLs were designed for multiple applications, and are capaible of 512  
(or more) channels, but the CB channel switch limits selection to 40 channels.   
Add a couple of switches in strategic places, and you get channels outside the  
CB frequency range, and the "A" channels that are the "holes in the frequency  
allotments".  The disadvantantage of PLL mods is that on many radios, there is  
no smooth transition from CB frequencies to the "outbands" ... you get jumps  
like "switch 1 and 2 up for normal 40, switch 1 up for 27.065 to 26.085 from  
channel 4 to 23, switch 2 up for 26.035 to 26.065 in channel 10-40 positions"  
.. you get the idea.  Essentially you're doing binary programming of the PLL  
by hand.

Most CBs can be switched by changing the crystal frequencies, creating entirely  
new 40 channel bands wherever the outbander wants, within the radio's TX/RX  
range.  There are recent innovations which allow radios that were formerly  
"unmodifiable" (those with ROM PLL chips) to be modified.  

Obviously, this is all ilegal.  The bands above and below CB may be empty, but  
they are still allocated to various services, like old public service bands,  
ship-to-shore bands and government frequencies.  In foreign countries, the  
outband frequencies may be allocated to emergency frequencies, which may cause  
_real_ problems during peak skip times.  The FCC recently started to fine some  
outbanders that were causing problems with government radio services.  

From all the outbanding activity that you hear about, it could mean a variety  
of things.  Either the CB service is out of control, or more channels are  
needed.  Both are true, but does CB deserve more frequency space?

Greetings Netters!

I have been following this thread for quite a while and have found
much useful information concerning CB.  That is why I am hoping for
help now.

I would like to purchase a handheld CB unit.  The unit would mostly be
used for communication with mobile units.  I need:

40 channels (preferably digitally displayed)
Full 4 watt power  
Squelch control
Rechargeable batteries/battery packs (at least as an option) 
Rubber ducky antenna
Belt clip 
Handheld speaker/microphone 

The $$ range I am aiming for is under $100.  I have flipped through
the RS catalog and don't see anything exactly like I need (please
correct me if I am wrong!).  I have heard about a Cobra (HT-40?) and a
Maxon unit that sound like they may fit the bill.  Part of my problem
is that I do not know where to look or who to get a catalog from.  

Please feel free to email me with information.  If there is interest,
I can post a summary of model information.

Thanks All!

Unfortunately, you seem to forget that there are MILLIONS of CB 
transceivers out there still in use.  For the FCC to decree the 11meter 
Citizens Radio Service is no longer in effect, and would everybody please 
turn in their CB's at the nearest Federal Building is absurd (though, if 
the FCC *could* tackle this task, you'd bet they would).
 
They spend the money hunting the real "butt-head" abusers of the band; 
the rest basically fend for themselves...and pay the price.

Hi,  

  Like the other have said, there are many types of antenna but the most common 
type is the vertical ground plane.  The details are too much to describe here
but the basics are :

  The vertical and rad-  |
ial elements are all ~   |
108 inches long.         |
                         |<- Radiator element, insulated from the radials,
