CI-2728-410 ComDat® VHF/WAAS GPS/XM

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.

Not compatible with most hand-held GPS receiver systems.

Applications

Single and twin engine piston aircraft for applications of this antenna design. Some light turbine and light jets. Consult your FBO or installation shop for best application information.
