GPS Antenna

This high-precision antenna is shipped with all GPS-Synchronized Time Servers and Time & Frequency Standards.  It provides 40 dB of gain with very high out-of-band rejection performance.  Selected specifically for its excellent group delay flatness and unit-to-unit repeatability, the quality of this antenna is critical to delivering 10 ns level time transfer from the Meridian II.
  • Weatherable polymer, all-plastic, non-corrosive, enclosure.
  • Noise Figure: 2.5 dB Max.
  • Group Delay Flatness: < 2 ns peak-peak 1575.42 MHz +/- 1 MHz.
  • Band Rejection: 30 dB @ 1535 MHz, 60 dB @ 1615 MHz.
  • Voltage Range 2.5 to 5 V.
  • Will drive up to 250 feet of factory-supplied cable.  For cables lengths greater than 250 feet, a GPS preamplifier is required.

GPS Preamplifier
GPS Low-Noise Amplifier

The G-LNA2 is a very high-performance, low-noise, inline amplifier for difficult GPS signal environments and long cable runs (greater than 250 feet of factory-supplied cable).  For more information on the preamplifiers click here.  For installation instructions with an EndRun antenna kit, click here.

The following table shows the number of preamplifers we recommend for each GPS antenna installation using our GPS receiver and our factory-supplied cable.  Installations using other cable types may have different preamplifer requirements.

GPS Splitter
GPS Splitter

The smart GPS Splitter is a one-input, two-output device.  In the normal configuration, one of the splitter RF outputs (J1) passes DC from the connected GPS receiver through the splitter to the antenna, allowing the GPS receiver to power both the antenna and the splitter amplifier.  The other RF output (J2) is DC loaded with a 200-ohm resistor to simulate the antenna current draw.
  • GPS L1 and L2 bands with excellent gain flatness.
  • 20 dB minimum gain block.
  • One RF output is DC loaded with a 200-ohm resistor to simulate antenna current draw.
  • TNC connectors.
  • Ask about interconnect cables.  Various lengths are available.

Lightning Arrestor
Lightning Arrestor

The Lightning Arrestor helps protect your GPS installation from damage due to lightning strikes.  It is installed between the antenna and the receiver, where the cable enters the building.  It is designed to pass the DC voltage that is needed to power the antenna and/or preamps without degrading the GPS signal.
  • DC voltage up to 15Vdc.
  • Spike protection to suppress spikes over +16.5V to the DC Power Supply.
  • Capable of 20,000 Amp maximum surges.
  • Frequency range of 800 MHz to 2.5 GHz.

Fiber Optic Link
Broadband Fiber Optic Link

The AFL3430 is an ideal solution for GPS receiver installations that require either extended antenna cable runs, enhanced lightning protection, or Tempest (RED/BLACK) isolation.  For more information on the Fiber Optic Link click here.
