Mobile GPS antenna

Coming up with small size and ruggedness, RV-19 is designed mainly to meet the robust demand for a GPS antenna that can maintain GPS signal stability for automatic vehicle locating and navigation even in a harsh environment.

** Universal connectors** AntiTheft & Double Lock

Overview

RV-19 is the integration of a high performance GPS patch antenna and a low noise amplifier into a low profile, extremely compact and fully waterproof enclosure. When connected to a GPS receiver with 2.5~5.0V DC antenna power, RV-19 provides excellent signal amplification and out-of-band rejection for that receiver.

Features

• Ultra-low input voltage and power consumption with high gain
  (Input Voltage as Low as 3V ; Current Consumption as Low as 4.7mA ; Overall Gain as High as 20 db)
• Low noise figure / Fully weather proof
• Ultra-high Sensitivity / Compact construction
• Excellent temperature stability
• GPS antenna with double threaded bolts and through holes for cable routing with course
• Fine treaded pitch locking for wing-nut fastener and lock-nut to prevent vibrations and un-authorized
  removal
