Product Attributes
First of it's kind, the CI 2680-500 combines four separate antenna funtions into one. Three different connections are on the base plate. TNC for GPS, SMA for popular satellite radio and/or weather data systems and BNC for combined VHF/Orbcomm. The BNC VHF/Orbcomm requires the Avidyne DC50 coupler, allowing the VHF side to operate as Comm 2 or as Orbcomm TX/RX.
This model encompasses what the ComDat concept is all about. Installers will save time and money placing one antenna instead of four. Pilots will appreciate the reduction in the number of antennas on their aircraft and reduced drag resulting in fuel ecomony and higher speeds.
The CI2680-500 features super tough construction for today's bigger and higher speed aircraft. Built in harmonic suppression filter limits VHF/GPS co-site interference.
