The CI2580-200 ComDat VHF/GPS antenna is designed meet specific GPS WAAS Gamma 3 requirements of the Garmin G1000 system. This ComDat antenna provide 80 dB of VHF harmonic suppression which allows VHF and GPS operation in one radome without the use of in-line filters. This antenna has passed the demanding direct effects of lightning environmental testing. The Gamma 3 WAAS allows for primary navigation using GPS for all phases of flight including precision LPV approaches.
