VHF/GPS/XM WX ANTENNA/26.5DB

The CI 2480-400 is the first ComDat to provide VHF, GPS and XM® Weather Data in a single, combined antenna. Patented design offers XM® approved performance for popular WX systems from Garmin® and Avidyne®. Built-in 80dB low pass filter protects both GPS and XM® antennas against unwanted VHF interference. 26.5dB GPS amplifier operates with Bendix-King® GPS and other GPS receivers requiring this gain value. With the Comant CI 511 GPS Attenuator, the GPS will function with popular Garmin® GPS systems requiring 17dB gain amplifiers. Helicopter rated, this model has been tested under the toughest RTCA DO-160D environmental conditions.
