GPS/Datalink (CI-2480-101)

Frequency · 1575.42 MHz 17dB Gain 118-150 MHz Unique in concept and design, the CI-2480-101 ties the newest avionics systems into a simple, sleek antenna package. Using the CI-248 radome, this antenna provides GPS for Garmin™ receivers and ORBCOMM™ Data Link Capability in a single footprint that matches standard VHF antenna configurations. This means the antenna offers nearly a "drop-in" installation process for your avionics technician. The ORBCOMM™ LEO satellite constellation brings real time weather and email within easy reach of any pilot. Plus, the CI-2480-101 GPS amplifier is specifically built for Garmin™ receivers, providing optimum GPS performance. Built-in high performance notch filter eliminates the need for in-line filters. Installations are not constrained with GPS/VHF spacing considerations.
