GPS 4/...

Active Receiving Antenna for the 1575 MHz NAVSTAR

GPS Satellite Navigational System

DESCRIPTION

Full hemispherical coverage due to quadrifilar helix antenna element.
Built-in high gain, low noise amplifier.
Input filter for thorough RF-overload protection.
Right-hand circular polarization (RHCP).
High rejection of cross-polarized reflections prevents fading caused by

multipath propagation.
5 V supply voltage (3 V respectively 12 V available on request).
DC supply via RF-connector.
EMC tested to IEC 801 and IEC 255.
Total design carried out to make the antenna withstand tough

environments.
Comprehensive range of accessory mounting brackets available.
Colour opportunities:

White (Standard)
Black
Sand
