Coaxial antenna
From Wikipedia, the free encyclopedia
A coaxial antenna (often known as a coaxial dipole) is a particular form of a half-wave dipole antenna, most often employed as a vertically polarized omnidirectional antenna.

[edit] History
Arnold B. Bailey was granted US patent 2,184,729 [1] for "Antenna System" on December 26, 1939.
[edit] Configuration
In the most basic form, a quarter-wavelength section of coaxial cable is prepared such that the inner and outer conductors are separate but still attached to the remaining cable.
The outer (sheath) conductor is connected to a quarter-wavelength conducting sleeve into which the cable is inserted, and the inner conductor protrudes vertically above the sleeve for a quarter-wavelength.
[edit] Other "coaxial antennas"
Dipole antennas may be successfully constructed mostly or entirely from coaxial cable, and are often given the name "Bazooka". However, such antennas are not coaxial antennas in the sense of this article.
