DESCRIPTION
Vertical omnidirectional antennas
radiate in a pattern similar to a
horizontal doughnut. Their gain is less
than that of a yagi antenna which
concentrates radiation in a single
direction. This reduced gain limits the
effective range of the omnidirectional
antenna, but proves effective when
directivity is not desired.
Omnidirectional antennas are useful in
short range applications where their

use eliminates the need for antenna
alignment. Omnidirectional antennas
are also useful on the control end of a
polling system.
When an omnidirectional antenna is
used on the control end of a polling
system, a yagi can be used on each
slave unit for maximum gain and
reduction in possible interference due
to the front to back ratio gain reduction
of the yagi antenna.
The 4008 antenna swivels 90° at the
base to allow the antenna to remain
vertical with the base mounted either
vertically or horizontally .
Designed for indoor mounting, this 7"
whip offers flexibility in mounting and
dependable performance for short
range systems.

Part 4044 allows the bulkhead connector
(4024) to be mounted on a right angle bracket
which has hardware to allow mounting the
antenna vertically on a vertical pipe.
To insure specified operation, this antenna
must have a conductive surface under it
when it is mounted. Mounting the antenna on
a metal electrical box provides a satisfactory
ground plane.
When mounting the antenna on a mast,
accessory 4044 provides an adequate
ground plane for 2.4GHz operation. When
used for 900MHz systems, a larger ground
plane is required (4045).
