Pedestal with Vortex
The Pedestal with vortex system consists of two
plastic helix type RF antennas, each mounted and
enclosed in pedestals. A transmitter/ receiver
power pack and RF antenna are contained in one
unit while the other pedestal has only an RF
antenna. 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 is an electrostatic radiator, a vortex bar
antenna which is suspended from the ceiling at an
elevation between 8 and 10 feet. Its length is less
than the pedestal separation. The antennas are
connected to the transmitter/receiver power pack
via shielded coaxial cables.
Components:
• Power Pack
• RF antenna (helix)
• Electrostatic field vortex bar antenna
• Non-metallic Mounting Enclosure
