Micromax Plastic RF Antenna with
Wire Cloth
The Micromax with wire cloth system consists of
two plastic helix type RF antennas, each mounted
and enclosed in plastic housing pods suspended
from the ceiling or mounted to the floor. The
housings are faced toward each other at a typical
distance range from 3 to 24 feet depending upon
the installation. In between the housings lays an
electrostatic radiator, a wire cloth antenna whose
length is less than the separation between the
pods. The wire cloth is usually recessed in the
floor or sometimes laid on the surface 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)
• RF antenna pod
• Electrostatic field wire cloth antenna
• Typical cosmetic mounting enclosure

Sensormat II with wire cloth
The Sensormat II with wire cloth system consists
of two patch RF antennas and an electrostatic field
wire cloth antenna. The patch antennas are placed
on one side of the wire cloth at a typical distance
of 4 feet. The Sensormat II physically covers a
typical exit path from 3 to 10 feet wide, depending
upon the installation. The wire cloth and the patch
antennas are recessed in the floor. 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 patch antenna
• Electrostatic field wire cloth antenna
• Typical cosmetic mounting enclosure

Formica laminated particle board is currently used
to assemble the non-metallic and cosmetic
mounting enclosures referred to above.
Enclosures could be constructed of similar
materials, i.e. plastic, fiberglass, etc. without
affecting the generated fields. The materials used
and the enclosure dimensions may vary for
custom installations.
