High Gain GPS Receiving Antenna Compatible with Double RTK Centimeter-Level Positioning Receiver (RTK Measuring Device)

Technical Highlights:

In practical application and usage, this antenna can assist geodetic surveying and topographic mapping in establishing high-precision control networks, provide mechanical positioning and navigation for the construction of roads, bridges, and tunnels, support the operation of agricultural unmanned agricultural machinery and farmland management, ensure accurate positioning for UAV surveying, inspection, and logistics distribution, and also assist in marine surveying and offshore platform monitoring. For usage, attention should be paid to installing it in a horizontal position with an unobstructed view and far from interference sources; connecting it with low-loss coaxial cables over short distances and ensuring proper sealing; providing a stable filtered power supply; and regularly inspecting its appearance, cleaning up debris, and testing its performance to ensure long-term reliable operation.

‌Core Performance‌

This high-gain GPS receiving antenna is specifically designed to be compatible with dual RTK centimeter-level positioning receivers (RTK measuring devices) and serves as a key component for achieving accurate centimeter-level positioning. It is widely used in fields such as surveying and mapping, engineering construction, agriculture, UAV navigation, and marine surveying. It boasts significant advantages in technical parameters: it supports GPS bands including L1 and L2, with a typical gain of [X] dBi; adopts right-hand circular polarization (RHCP) and 360° horizontal coverage; features an output impedance of 50Ω and a VSWR (Voltage Standing Wave Ratio) of ≤1.5, along with a phase center error of ＜2mm. Equipped with a built-in low-noise amplifier, it offers an active gain of 40±2dB, a noise figure of ≤1.5dB, an operating voltage range of 3-5.5V, and an operating current of ≤45mA. This antenna can efficiently receive weak satellite signals, resist multipath interference, and exhibits environmental adaptability with resistance to high and low temperatures, water, and ultraviolet rays, providing stable and high-quality signal input for RTK devices.
