Antenna Information For C.B. Radio

unit, I have a lot of copper wire,copper tubing that type of
stuff, would like to know suggested height if that matters.
Will be using this in a city.
Thank-you,if you have any info. Email me way...@ccinet.ab.ca

least 6ft. The copper tubing will make good plumbing material. Use tubing
large enough to pass the CB radio through, about 6" is large enough.
Connect the far end to the drain pipe of your house and insert the CB.
Follow up with a large bucket of water.
: Does anyone know how to make an antenna for a base C.B. radio

I've seen several posts along this line recently and have to
ask "What are you trying to prove?" Is your sense of self worth
so low that your only answer to someone is to denigrate them
because they aren't a licensed amateur? Do you make snide
comments to the public when they come to your Field Day station?
Our bands are granted to us not by just the amateur population
but the entire population of the country. I'm sure responses such
as above really help our cause when the country looks to us as
a pool of trained technical resources. I guess your view is
that those trained resources can only be counted on to help
themselves and not the general public? Nice attitude and
interpretation of Part 97.1. :-(
In answer to the original question, a 1/4 wave ground plane antenna
would work fine. The higher the better. A 1/4 wave CB ground plane
antenna would have a vertical element (piece of 1/2" copper tubing
would do fine) that is attached to the center conductor of your coax
and it should be about 8 1/4 feet high. The ground plane should be 3 or
4 radials (also of tubing if you like) that are about the same length
and attached to the braid of your coax. I'd start with 8 1/2 of tubing
for the vertical element and trim it as necessary to lower your SWR.
Also, please forgive the rather boorish response given by the previous
poster. He is definitely *not* representative of all amateurs (just a
loud vocal minority.)
Another source of information on antennas and their construction is
the ARRL Antenna Book. Should be available at a public library near
you or you can order it directly from the ARRL at 860-594-0200.

underground antennas. No joke it has been done. Plans are included in the
reference.
You can get out further with a Wet Noodle and a Linear than you can with

I'm not sure what frequency the CB band is, but
the formula is :
the length of wire in feet = 468/(the frequency in Mhz)
For the CB band that might be:
18 feet = 468/26.0 Mhz.
Take this 18 feet of wire and cut it in half. Attach (solder is best)
one end to the center feed point and attach the other
9 foot wire to the ground feed. Then connect the antenna
feed line to you CB radio. Place the 18 foot antenna as high
up as you can get it. The higher the better, but at least, 9 feet
up.
If this confussing, go to the library and check out an
antenna book, "The ARRL Antenna Book" is best, and look
up DIPLOES.
Good luck and don"t be put off by some of the idiot answers.
