1575.42MHz 28dBi gain RHCP GPS Active Antenna

Product Introduction

1. High Gain 28dBi – Provides exceptional signal reception for weak GPS signals, ensuring reliable positioning even in challenging environments.

2. RHCP Polarization – Right-hand circular polarization matches satellite signals perfectly, minimizing signal loss and multipath interference.

3. Low VSWR ≤1.5 – Excellent impedance matching reduces reflected power and maximizes signal transfer.

4. Compact and Lightweight – Tiny 16×38mm footprint and 50g weight make it easy to integrate into space-constrained devices.

5. Built-in Low Noise Amplifier (LNA) – Active design amplifies received signals to compensate for cable losses, ideal for long cable runs.

Application Scenarios

1. Precision Agriculture – Used in tractor guidance systems and automated farming equipment requiring accurate GPS positioning.

2. UAV/Drone Navigation – Provides stable satellite reception for flight control and autonomous missions.

3. Vehicle Tracking Systems – Enhances GPS signal strength for fleet management and anti-theft tracking devices.

4. Surveying and Mapping – Suitable for high-precision geodetic receivers and GIS data collection.

5. Timing and Synchronization – Employed in network time servers and base stations requiring accurate GPS timing.

FAQ

Q: What frequency does the GLSDL3816 antenna operate at?
A: It is designed specifically for the GPS L1 frequency at 1575.42 MHz.

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 actual antenna element gain is lower, but the LNA boosts the signal to 28dBi to compensate for 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 receivers.

Q: What is the polarization of this antenna?
A: It features Right-Hand Circular Polarization (RHCP), matching GPS satellite signals for optimal reception.

Q: What is the VSWR specification?
A: VSWR is ≤1.5, indicating excellent impedance matching and low signal reflection.
