Detail Information
Description :
Small size and ruggedness, demand of lorry locating and car navigation GPS antenna that will sustain harsh environment.
The antenna system GA50Abis 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 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.
