GPS/4LTE Combo External Antenna (DLGPS/LTE-C3) is a high-performance external antenna designed to provide reliable signal reception for both GPS and 4G LTE communication systems. The GPS section operates at a center frequency of 1575.42MHz±1.023MHz with a bandwidth greater than 10MHz, offering excellent signal stability and precision. It features a right-hand circular polarization (RHCP) with a gain of 5dBic based on a 7×7cm ground plane, ensuring strong satellite signal acquisition and consistent positioning accuracy. The antenna’s input impedance is 50 Ohms with a voltage standing wave ratio (V.S.W.R.) of ≤2.0, supporting efficient power transfer and minimal signal reflection.
The integrated low-noise amplifier (LNA) enhances the received GPS signal with a typical gain of 28±3dB and a noise figure of ≤1.5dB, ensuring superior sensitivity even in weak signal environments. It operates on a DC voltage of 3.3±0.3V and consumes a typical current of 8.5±3mA at 3.3V. The GSM/LTE section supports a wide working frequency range from 700MHz to 2700MHz, covering all major global LTE bands. It provides a peak gain of 2dBi at both 900MHz and 1800MHz with a 2:1 V.S.W.R., maintaining efficient communication performance across multiple frequency bands. The antenna exhibits omni-directional azimuth characteristics and linear polarization, enabling uniform signal coverage in all directions.
Built from durable and high-quality materials, the GPS/4LTE Combo External Antenna incorporates a ceramic dielectric antenna element housed in an ABS enclosure with an FR4 PCB base and a tinplate shield for enhanced signal integrity and mechanical protection. It uses an RG174 RF cable and can be equipped with various connector options such as SMA to accommodate diverse installation requirements. The back surface includes a 3M467MP adhesive sticker for easy and secure mounting. This compact antenna is ideal for use in telematics, vehicle tracking, navigation systems, IoT devices, and other wireless applications requiring dependable GPS and LTE performance in a single unit.
