The rubber duck dipole antenna is a standard dipole antenna. Dipole antennas
are pictured in Figure
. It is also
called a doublet antenna. It is an omnidirectional antenna that is suitable for
many applications. The antenna is a straight electrical conductor. Dipole
antennas can be oriented horizontally, vertically, or on a slant. Dipole
antennas are supplied with some Cisco Aironet access points and client devices.
The antenna has an articulated base that can be rotated 360 degrees at the
connection point and from 0 to 90 degrees at its knuckle. The dimensions are
shown in Figure
. The
radiation patterns are shown in Figures
and
.
Indoor
diversity dipole antennas with a base are designed to extend the range of
Aironet LMC client adapters and has two MMCX (2) connectors instead of the
RP-TNC connector. The articulated base is shown in the Figure
. The dimensions
are shown in Figure

patterns are shown in Figures
