Key Features of the Multi-Band UAV Antenna
Engineered for light, high-precision drones where weight, reliability and signal quality all matter.
High Gain & Wide Beam
The passive antenna offers high gain and a wide beam for good reception of low-elevation signals, and can still receive satellites normally in environments with severe obstruction.
Multi-System, Multi-Frequency
A wide operating bandwidth supports GPS, BDS, GLONASS and Galileo, including the globally networked B3 band, which greatly improves system stability.
High Out-of-Band Rejection
Effectively avoids system instability caused by signal interference from communication base stations and other sources.
Small & Lightweight
Very small size and light weight (≤16 g) keep payload low, which is critical for light UAV platforms and longer flight missions.
Reliable, Protected Structure
A reliable structure with IP65 protection improves the reliability of the whole UAV, including water resistance and impact resistance.
Built-In Low-Noise Amplifier
33 ± 2 dB LNA gain with a noise figure of ≤1.3 dB and a wide 3.3–12 V DC supply for easy integration with common flight controllers and receivers.

How to Choose the Right UAV Antenna
A quick guide to matching a UAV GNSS antenna to your drone platform.
Confirm GNSS Systems
Check whether your receiver needs GPS, BDS, GLONASS and Galileo, and which bands (L1/L2, B1/B2/B3, and others).
Check Weight & Size
Light UAVs benefit from a lightweight antenna. Confirm the mounting space for Φ49.8 × 38 mm.
Match LNA Gain & Voltage
Make sure your receiver's antenna power (DC 3.3–12 V) and cable length suit the 33 ± 2 dB LNA.
Review the Environment
Consider signal obstruction, nearby base-station interference, temperature range and weather exposure.
Confirm the Connector
The antenna uses an SMA male connector. Confirm cable and adapter compatibility with your receiver.
