Product Description

Vehicle Locating Small GPS/GSM/WIFI Antenna GWA-650L



    Product Character



    Small size and ruggedness; demand of vehicle locating and car navigation GPS antenna that will sustain harsh environment.

    • Low noise figure
    • Fully weather proof IPX7
    • Ultra-high Sensitivity
    • Compact construction
    • Excellent temperature stability

    The antenna system GWA-650L 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.


    GPS/GSM/WIFI 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.
