GPS AntennasGPS 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
