The function of the GPS/BeiDou plus 4G full-network receiver antenna is to convert the electromagnetic wave energy of radio signals transmitted by satellites and base stations into electrical power that can be utilized by the receiver’s electronic components. Our GPS/BeiDou antenna consists of a ceramic antenna element and an active amplifier, while the 4G full-network antenna uses a PCB microstrip design. Encased in a plastic shell, it features waterproof and moisture-resistant properties. The product is compact, with 3M double-sided adhesive on the bottom of the antenna for easy installation and use.
