Vehicle Locating Small GPS/GSM Antenna
MODEL: GAF-65
Small size and ruggedness, demand of vehicle locating
and car navigation GPS antenna that will sustain harsh environment.
The antenna system GAF-65 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 +2.5~ 5.5V DC antenna powers 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.
