Active GPS Marine Antenna

The small size and ruggedness of this antenna is a prerequisite for an antenna in the high demand of vehicle locating and car navigation GPS antenna that will sustain harsh environment.

** Universal connectors** AntiTheft & Double Lock

Overview

The antenna system RV-76 is the integration of a high performance GPS patch antenna and a state-of-the-art low noise amplifier into a very low-profile, extremely compact and fully waterproof antenna-signal enclosure. When connected to a GPS receiver with +2.5 to +5.5 VDC antenna power, it provides excellent signal amplification and out-band-rejection for that receiver.

Features

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-authorize removal.

• Low noise figure / Fully weather proof
• Ultra-high Sensitivity / Compact construction
• Excellent temperature stability
