Comant CI-401-460

Overview

The CI 401-460 is set apart from other antennas because, in addition to GPS, the antenna provides popular Satellite Radio and Weather Data signal capability. Now installers can quickly place this TSO'd antenna on limited space areas. What's more, installers can provide satellite entertainment and/or weather data systems for their customers without adding another antenna.

The newly redesigned 401 Series ARINC footprint has proven to be a versatile antenna. This model contains a highly stable GPS amplifier that offers gain performance at 27.0 to 31.5 dB while providing excellent Satcom rejection at 40 dB minimum.
