transmitter/receiver power pack, RF antenna, and
an electrostatic field radiator plate are contained in
one unit while the other pedestal has only an RF
antenna and another electrostatic radiator plate.
The housings are faced toward each other at a
typical distance range from 3 to 6 feet depending
upon the installation. The antennas are connected
to the transmitter/receiver via shielded coaxial
cables.

Concealed Ceramic RF Antennas with
wire cloth
The Concealed ceramic RF antennas with wire
cloth system consists of two helix type RF
antennas, each resting on the ceiling tiles. The RF
antennas are faced towards each other at a typical
distance range from 3 to 24 feet depending upon
the installation. On the floor between the RF
antennas lays an electrostatic radiator, a wire cloth
whose length is less than the separation between
the RF antennas. The wire cloth is usually
recessed in the floor or sometimes placed on the
floor and covered with a rubber mat. The antennas
are connected to the transmitter/receiver power
pack via shielded coaxial cables. The
transmitter/receiver power pack has an optional
cosmetic enclosure.
Components:
• Power Pack
• RF antenna (helix)
• Electrostatic field wire cloth antenna
• Typical cosmetic mounting enclosure
