Comant ComDat VHF GPS Antenna, 17db GPS Preamp

The design that stated a revolution in multifunction antennas for general aviation. Combines both GPS and VHF Com functions in a single footprint. Same 4-hole mounting configuration as the popular CI 121 VHF and CI 420 GPS antennas. Separate connectors for GPS and VHF, GPS is protected from VHF harmonics with our exclusive built-in 80dB harmonic suppression filter. The CI 2480-201 GPS function is designed for use with Garmin’s™ panel mount GPS systems that require 17dB gain. The CI 2480-201 is standard equipment on many aircraft OEMs including Robinson Helicopter, Cessna, Mooney and Piper.
