GPS Marine Antenna

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

** Universal connectors** AntiTheft & Double Lock

Overview

The antenna system RV-16 is the integration of the high performance GPS patch antenna and a low noise amplifier into state-of-the-art low a very low profile/extremely compact/fully waterproof antenna signal enclosure. When connected to a GPS receiver with +5V DC antenna power it provide 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
