ANT-81A Antenna

Overview

The ANT-81A is an electronically steerable phased array traffic alert and collision avoidance system (TCAS) antenna with four top-loaded monopulse elements. The traffic alert and collision avoidance system (TCAS) processor selects one of four antenna beams and determines the bearing of the intruder aircraft based on the phase difference of the transmitted and received signal. The ANT-81A provides directional and omni pattern interrogation and reply coverage for Honeywell CAS 100 systems.

The antenna is available in white and gray.
