Vehicle Locating & Marine Small GPS Antenna
Small size and ruggedness, demand of vehicle locating and marine navigation GPS antenna that will sustain harsh environment.
The antenna system GA-62 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 +3~5V 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.
