The SM-76G is the integration of the high performance GPS/GLONASS patch antenna and a state-of-the-art low noise amplifier into a very low profile/extremely compact/fully water resistance enclosure. When connected to a GPS receiver with +2.5 to +5.0 VDC antenna power, it can provide excellent signal amplification and out of band filtering & rejection for that receiver. Last but not least, the design of a double lock (or an anti-theft locking nut) provides sound security for the product.




Features:

  • Low Noise Figure/ Fully Weatherproof/ Ultra-high Sensitivity
  • Compact Construction/ Excellent Temperature Stability 
  •  Applications:

  • AVL/Fleet Management Systems /Car Navigation/Marine GPS
  • Weather Balloon/Security Surveillance/External Antenna for Handheld GPS
