Bar Antenna System Installation
Introduction
The Bar Antenna typically receives signals transmitted by personnel
and asset Tags (transponders). The Bar Antenna is an excellent
antenna for mounting above or beside a doorway (sometimes above
the ceiling tile) to monitor or control access to an entry/exit point of a
facility.
Antennas of this type radiate RF energy most efficiently in a direction
broadside to the antenna – and radiating less energy off the edges
(Figure 28). Partial rotation of the antenna forward or backward, and
from side-to-side will produce noticeable results.
