GNSS Antenna Navilock NL-203AA high-gain, SMA connector, 5 m cable, outdoor

Navilock NL-203AA is a high-gain GNSS antenna designed for outdoor installations. It has an SMA connector and a fixed 5 m cable to connect directly to GNSS receivers, navigation units and tracking devices. The antenna enhances satellite signal reception to support positioning, navigation and timing in vehicles, marine vessels and surveying setups that require consistent GNSS performance.

Advantages

The high-gain design increases sensitivity to weak satellite signals and helps maintain a stable fix in areas with limited sky view. The integrated 5 m cable simplifies installation by providing immediate connection length without extra cabling, and the SMA connector is compatible with a wide range of GNSS receivers and trackers. The outdoor-capable housing offers protection against environmental exposure for long-term use in vehicle, marine or stationary mounting applications.

Suitable for

• Vehicle tracking and fleet management installations
• Marine navigation and positioning systems
• Surveying and geolocation equipment requiring external antennas
• Stationary outdoor setups for timing, telemetry or monitoring

Key specifications

• High-gain GNSS antenna type suitable for multiple satellite constellations
• SMA connector interface for receiver compatibility
• Fixed 5 m cable for direct connection to devices
• Outdoor-rated housing for protection against weather exposure

How to use

Mount the antenna in a location with an unobstructed view of the sky for optimal satellite reception. Route the fixed 5 m cable to your GNSS receiver or tracker and secure the SMA connector to the receiver’s antenna input. Ensure the antenna housing is fastened according to the mounting surface and that the cable is protected from sharp edges or pinch points. After connection, verify receiver settings and perform a signal acquisition to confirm improved GNSS performance.

Recommendations

Place the antenna as high as practical and away from large metal obstructions or sources of RF interference. Regularly inspect cable routing and the antenna housing for damage or corrosion to maintain reliable signal reception. For installations on vessels or vehicles, use weather-resistant mounting hardware and check connections periodically.
