Overview
Completely redesigned 401 Series ARINC footprints 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 40 dB minimum. Plus, this antenna presents very low noise levels at 3.8 dB maximum.
The new design features a nickel plated aluminum base plate with an integral 'O' ring for sealing.
What's more, the built-in voltage regulator allows the antenna to operate smoothly anywhere from 4 to 24VDC, affording a wide variety of applications such as Honeywell, Bendix-King, L3 Avionics, Universal Avionics and UPS Navigation systems.
