It is pretty amusing.  You also forgot the important
"1/4 wave" and "1/2 wave" which are being left out in
the cold.  But normally it's always "3 feet."

I wouldn't say it's an internet fight, more like a

hate to see bad advice given out.

And I don't know what you mean by guessing correctly
when measuring coax. The only length you need is the
shortest length from the radio to the antenna. Like I
said before, I had an installation in one truck with
about 15' of coax. I moved it into a new truck and

Now if 15' is the magic number for CB, why is it the

19", so why did the manufacturer put 15' of coax on
the antenna? And why did shortening the cable not

Yes, and remember that the GMRS license fee covers 5 years so it is only

A 102 is what?

   A-ha, it's 8.5 feet!  A true 1/4 wave!  With coax in multiples of 9', you
should always enjoy almost a "flat match."  That's 1:1 SWR, for those who need
to be told what.

Well I tell you what.....

   I'm wiping the drops of spittle off my computer screen right now, because I
guess he told me what.

   Tom, you take things way to seriously.  I can't believe you just got into an
internet fight over coax length.  Lighten up, dude!  I'm glad you've always
guessed correctly when cutting coax.  I'm glad you can do math.  And by the way,
you're absolutely correct, 1/4 wave IS just under 9 feet, thus the "rule of
three."  It's just easier to round to 9, which works fine.

   Nevermind that I've installed CB's for a living for many years, and I've never
had an oddball length match well.  I'd be interested to know what your SWR match
is on your mobile, since you brought up the argument.

   But then again, I guess I've already been told what.

   Out.

Well I tell you what, I am an amateur radio operator
and I've used multiband dipoles for some time now. I
have a 4-band dipole up fed with about 50 feet of
coax. It is resonant on all four bands, even though
the same 50-foot length of coax is used for all four
bands.

In my mobile installation, for my 2m radio I have a
5/8 wave magmount antenna. The coax was originally 15
feet long. I didn't need quite so much coax so I
shortened it a few feet. The VSWR remained the same.

Now why does coax length only matter on CB and not
amateur radio? There should be no difference since
radio theory is the same no matter what frequency you
use. But for some reason coax length does not matter
for amateur radio use, but for some reason a lot of
CBers claim that coax must be X length.

3 foot lengths doesn't even make any sense for CB use
anyway, since 3 feet is nowhere near being resonant
anywhere on 27 MHZ. 1/4 wave on 27.2 MHZ is 8.60
feet, or just over 8 1/2 feet, which does not divide
into 3.

Again, I'll state the plain fact: If your antenna is
properly installed, coax length does not matter. You
just need it to be long enough to get from the radio
to the antenna feedpoint.

Good Morning, Tom.

I took a look at the antenna you're asking about and after looking
through the advertised specs I noticed the price.  I can't imagine
you'll find this antenna very serviceable.  $20 doesn't buy much and
surely this thing is constructed cheaply.  Since you're soliciting
some advice here I'll give you mine.  Go out and pony up the $80 it
takes to purchase a Wilson 1000.  You will not regret it, and if you
ever do decide to sell it you'll likely find it EASY to get at least
$50 back out of it.  Those antennas have a terrific reputation for
good reason.  They're built extremely well and RX/TX wonderfully.
The Wilson also comes with a correct length of coax attached with a
PL-259 end connector ready for use.  I use mine for 11 and 10 meter
with SWR from 26.250 to 28.400 under 1.5 to 1.

Hope this helps.  Perhaps we'll see you on the air

A buddy of mine and I made an improvement to the metal plate used to ground the
ball mount of the 102" to the body of the truck. Manufacturer of the ball mount
gives you a mounting plate of about 1/16" thick and my friend who is a machinest
made one that is a half inch thick for a better ground. On 40 I have a flat 1

   Again, there is no reason to have your coax in
   multiples of 3 feet, 1/4 wave, 18 feet, or whatever
   other myth is out there. As long as your antenna is
   properly installed & tuned, it just doesn't matter
   what the coax length is.

   Here's are a couple of good webpages which discuss
   these coax length myths:

   http://www.signalengineering.com/ultimate/coax_basics.html
   http://www.stu-offroad.com/misc/myth-1.htm

   I know a lot of people still won't believe that the
   length of coax isn't important, but it's true. If the
   length of your coax is changing the SWR in your
   antenna system, then you have an improperly tuned
   system, and coax length isn't going to solve the
   problem.

Again, there is no reason to have your coax in
multiples of 3 feet, 1/4 wave, 18 feet, or whatever
other myth is out there. As long as your antenna is
properly installed & tuned, it just doesn't matter
what the coax length is.

Here's are a couple of good webpages which discuss
these coax length myths:

http://www.signalengineering.com/ultimate/coax_basics.html
http://www.stu-offroad.com/misc/myth-1.htm

I know a lot of people still won't believe that the
length of coax isn't important, but it's true. If the
length of your coax is changing the SWR in your
antenna system, then you have an improperly tuned
system, and coax length isn't going to solve the
problem.

Don't try this in practice though.  Stick with the "multiples of three" theory
and you'll be fine.  ANd coiling the coax is a bad idea too.  Ask me how I know.

It's a myth that coaxial cable has to be X length or X times a
certain length. It only needs to be as long as needed to get from
the radio to the antenna. The only time it needs to be a certain
length is in phased arrays (two antennas connected to the same radio)
and then they only need to be the same length.

The feedline should not be acting as a radiator. The quarter wave
antenna is one half of the dipole while the car body acts as the
other half, or more accurately a ground plane. As long as the coax
shield is attached to the vehicle body, the length of the coax will
not matter whatsoever.

The only time I've ever seen coax length matter was in a "groundless"
mobile antenna such as designed for use on an RV or boat.

But the myth that CB coaxial cable must be X x3' lengths has been
floating around for years, but has no basis in fact. Like I said,
coaxial cable should not radiate so the length used to get from the
radio to the antenna is not critical.

RJ, you sound like just the person to establish a REACT Team in your area.
There is a Team in LV. REACT would fit well with your Highway Watch

Greetings Everyone:

My name is RJ, appear to be the newest member to the group and have
been enjoying CB for thirty plus years (this certainly does not make
me "all knowing"). My humble shack is located in Clark County, NV,
approximately seventeen miles outside Las Vegas.

At present the CB equipment is one Cobra 2000, one RCI-2995, and the
antenna is a MACO V-Quad, IMAX 2000, and Double Bazooka dipole … the
dipole being my favorite.

I am the western region coordinator for Traffic Alert USA, a member of
Highway Watch, and  monitoring member of shortwave radio station
Deutsche Welle, CIRAF Zone 6. My call for TAU is NV18S, for the Nevada
Calling group it is KNV7BD, for regular on air contacts it is NC444.

Hoping to make on-air contact with many of you, and sharing information
within this group.

Thanks for having me.

Another point I should have mentioned is that the vertical radiator
is half of the vertical dipole while the 11-17' sheild on the coax
is the other half of the dipole, electrically, while the center
conductor is the feedline and the coil is a balun at the feedpoint.

You need at least a quarter wave feed line to the radiator or you will have a
difficult time with matching and impedance. The coiled excess acts as a balun
choke and prevents a feedback loop which will remodulate your carrier with FM.
There is very little loss and radio is tricked into seeing a great match.

I would cut the cable short and reattach the PL-259
connector.  There's no use in having 11 feet of coax
coiled up under the dash.  Having the coax coiled up
would make an RF choke.

Good Morning Everyone,
Got floods in OK and the upper Midwest, DEAN is trucking toward the
Yucatan which are immediate "Life Takers" so keep listening when you
can. We have Peru, Alaska and a war with Iraq that require our
vigilance and implementing our resources when we can contribute so do
what you can to organize monitoring on CH9 and CH39lsb networks in you
neighborhood. Also take a moment to post your efforts and readiness on
the group and encourage folks to activate when and if needed.
We already have in place network with REACT, Truckers etc. who
contribute daily by reporting accidents, bridges collapsing, tornadoes
etc. and every contribution is for our own good.
Thanks Much and much respect to all our volunteers.
