High Gain 28dBi – Exceptional signal amplification ensures reliable positioning even in weak signal environments or with long cable runs.
RHCP Polarization – Right-hand circular polarization matches satellite signals perfectly, minimizing multipath interference and signal loss.
Low VSWR ≤1.5 – Excellent impedance matching maximizes power transfer and reduces signal reflection.
Compact and Lightweight – Small 40×45mm footprint and 50g weight allow easy integration into space-constrained devices.
Built-in Low Noise Amplifier (LNA) – Active design compensates for cable and system losses, ideal for precision applications.
Precision Agriculture – Used in tractor guidance, yield monitoring, and automated farming systems.
UAV/Drone Navigation – Provides stable satellite reception for flight control, surveying, and mapping drones.
Vehicle Tracking Systems – Enhances GPS signal strength for fleet management, logistics, and anti-theft devices.
Surveying and Mapping – Suitable for high-precision geodetic receivers, GIS data collection, and construction layout.
Timing and Synchronization – Employed in network time servers, base stations, and power grid synchronization requiring accurate GPS timing.
Q: What frequency does the GLSDL4540 antenna operate at?
A: It operates at 1568±9 MHz, covering GPS L1 (1575.42MHz) and nearby GNSS bands such as Galileo E1 and GLONASS L1 (partially).
Q: What does 28dBi gain mean? Is it really that high?
A: 28dBi is the gain including the built-in low noise amplifier (LNA). The passive antenna element gain is lower, but the LNA boosts the signal to 28dBi to overcome cable and system losses.
Q: Is this antenna active or passive?
A: It is an active antenna with an integrated LNA, requiring DC power (typically 3-5V) through the RF cable (bias tee).
Q: What type of connector does it have?
A: The connector is typically SMA male or female (please check product variant), designed for easy connection to GPS/GNSS receivers.
Q: What is the polarization of this antenna?
A: It features Right-Hand Circular Polarization (RHCP), matching GNSS satellite signals for optimal reception.
Q: What is the VSWR specification?
A: VSWR is ≤1.5, indicating excellent impedance matching and low signal reflection.
