GNSS L1/L5 Magnetic-Mount Active Antenna
Are you facing these challenges when selecting a high-accuracy GNSS antenna?
- Unstable positioning in urban or high-reflection environments
- Need simple installation on vehicles, construction machinery, or agricultural equipment
- Evaluating L5 support in addition to L1
- Concerned about cable loss between antenna and receiver
- Looking for a waterproof external GNSS antenna
- Need different cable lengths or connector options
Features
1. Dual-Band GNSS L1/L5
Supports L1 (1575.42 MHz) and L5 (1176 MHz). The L5 signal reduces multipath effects, improving positioning accuracy in urban areas, near buildings, and around vehicles where reflections are common.
2. High-Sensitivity Reception with Integrated LNA
The integrated low-noise amplifier (LNA) amplifies weak satellite signals directly at the antenna. Typical LNA gain is 28 dB, with a typical noise figure of 1.5 dB, stabilizing your receiver front-end and compensating for cable loss.
3. Easy Magnetic Installation
The built-in magnet enables fast installation on vehicle roofs and metal enclosures. Magnet + magnetic-sheet models support installation on non-metallic surfaces using the included sheet.
4. IP67-Rated Enclosure
The IP67 enclosure supports outdoor and vehicle-mounted use. Suitable as an external GNSS antenna for equipment exposed to rain, dust, and harsh environments.
Active Antenna and LNA Function
GNSS satellite signals are extremely weak when they reach the earth’s surface. In vehicle-mounted and outdoor IoT devices, cable routing, antenna placement, nearby metal, and enclosure structure can further reduce signal strength.
This antenna integrates an LNA to amplify the signal immediately after reception. The result is a stable signal level at your GNSS receiver, improving overall positioning reliability in high-accuracy systems.
Selection Guide
| Item | What to Confirm |
|---|---|
| Operating Frequency | Supports dual-band L1/L5. Suitable for high-accuracy positioning, RTK, and multi-GNSS devices. |

Important Notes
- Install the GNSS antenna in a location with a clear view of the sky for stable reception.
- Metal enclosures, glass, plastic covers, and nearby cables can affect in-device performance.
- This is an active antenna and requires DC power from the connected GNSS receiver.
- If the connector is exposed to water, apply appropriate waterproof protection such as self-fusing tape.
- Verify reception and positioning performance in your final device before mass production.
