Cobham Comant CI-2480-216 ComDat VHF/XM Weather Antenna
We've completely redesigned our 401 series ARINC footprint GPS. This model contains an all new, highly stable amplifier that offers great performance. Gain performance at 26.5 to 31.5 dB provides excellent SatCom rejection at 40dB minimum. Plus, this antenna presents very low noise levels at 3.8 dB maximum.
The new design features a nickle plated aluminum base plate with an intregal 'O' ring for sealing. What's more the built in voltage regulator allows the antenna to operate smoothly anywhere from 4 to 24 vdc, affording a wide variety of applications such as Honeywell Bendix/King, L3 Avionics, Univeral Avionics and UPS Navigation systems.
