E. ANTENNA
UNIT
Circularly polarized antenna operating in the K band. All electrical components are enclosed in a sealed
metal housing to defeat radio frequency interference. Metal housing has a black polycarbonate radome
(housing) over it to protect the internal components, including the antenna lens, from physical damage and
from damage from the elements. Plastic housing creates a waterproof O-ring seal, allowing all-weather
operation outside of the patrol vehicle. Has aiming sights.
