1.2.7 RF INTERFACE
The stand-lone unit’s RF interface is a 50-ohm impedance matched
standard BNC/TNC connector as required by regulations. The RF in-
terface can operate without damage to the unit under DC short and
open conditions.
1.2.8 A
NTENNAS
Antenna type depends on the site requirements, and may be direc-
tional or omni-directional. The AW Base antenna is typically mounted
on a mast that elevates the antenna a minimum of 40 feet above the
average level of the terrain to support 50 miles distance range.
The total system gain allowable includes both the Radio-Modem and
the antenna. The table listed below is for ArWest antennas, however
the Gain values can be used with other antennas to determine Al-
phaWave Power Setting.
