Comant CI-2728-410

Overview

Comant’s ComDat triple function VHF/GPS/XM Weather antenna for twin and light jet aircraft is WAAS capable. Comant’s patented technology provides 80 dB of VHF harmonic suppression allowing VHF and GPS to function in one radome without in-line filters.

Specifically designed to meet the GPS WAAS Gamma 3 requirements for Garmin “W” systems. Enables primary navigation using GPS WAAS, including terminal navigation and approach to landing. XM Weather antenna is designed for low-gain systems such as the Garmin GDL-69/69A or Heads Up systems with shorter coaxial runs.
