Dimensional Drawing
Multifunctional GPS/BeiDou/GLONASS/Galileo/QZSS antenna is the role of receiving GPS/BeiDou/GLONASS/Galileo/QZSS combined satellite signals, a full range of environmentally friendly materials, in line with ROSH, SGS and other international standards. Internal devices all use the international first-line brand, the design program using bipolar tube and filter. High gain, Low power consumption, ans Strong anti-interference are GPS Antenna's features. Shell structure using ultrasonic design, the design of a good seal with a strong waterproof performance. Adapting pieces all through the strict salt spray test and pull force test. Finished products can withstand harsh environment with +85 degrees high temperature and negative 45 degrees low temperature. GPS antenna installation can be used magnet adsorption, double-sided adhesive paste, metal parts fixed ect. Our GPS antenna has good performance, and is industry-leading one. It can be used in the automotive, security, locator, tracker, T-BOX, handheld terminal, walkie-talkie, navigation, aviation, Tablet PC, industrial, intelligent furniture and other fields.
We has a strong development and design strength, GPS antenna can be designed and customized basing on customers' needs (electrical performance, structure, size, length, connection, etc.)
