Sorry to disagree but the wave length of a 1/2 wave CB antenna is 18
feet. The body is 9 feet and the antenna is 9 feet making a total of
18 feet. This is called a 1/4 wave antenna. Anything smaller has
what is called a base load, (a coil), that simulates a 9 foot antenna.
Therefor placement of any CB antenna is very important!
