GPS GLONASS antenna QOLTEC 57054 with magnetic base, 28 dB gain

Active GPS/GLONASS antenna QOLTEC 57054 with magnetic base and 28 dB gain is designed to receive satellite positioning signals for navigation systems, vehicle trackers, and surveying equipment. The antenna’s active element amplifies weak signals from GPS and GLONASS satellites, improving reception stability in urban canyons, under light foliage, and in other challenging environments. The magnetic base allows for fast, temporary mounting on metal surfaces without tools and provides a convenient solution for mobile or test installations.

Advantages

The antenna combines a high-sensitivity active element with 28 dB gain to increase signal strength and reduce position fix time. Its magnetic base ensures secure attachment to vehicle roofs or other metal surfaces while enabling quick relocation. The compact, weather-resistant housing is suitable for outdoor use and helps protect the internal electronics from environmental factors. The product is compatible with receivers that accept active GNSS antennas and can improve performance where passive antennas struggle.

Suitable for

• Vehicle tracking systems and fleet management
• Portable navigation devices and dashcam systems with external antenna input
• Surveying tools and GNSS receivers requiring signal amplification
• Temporary or field installations where rapid mounting and removal are needed

Key specifications

• Frequency support: L1 GPS and GLONASS bands (active GNSS reception)
• Gain: 28 dB
• Mounting: magnetic base for attachment to metal surfaces
• Housing: compact, weather-resistant enclosure suitable for outdoor use
• Cable and connector: integrated coaxial cable with standard external connector (length may vary by kit)
• Operating environment: suitable for typical automotive and field conditions

How to use

Position the antenna on a clean, flat metal surface with a clear view of the sky for best satellite reception, such as a vehicle roof. Route the cable to the GNSS receiver or tracker and connect the antenna to the receiver’s external antenna input. If the receiver requires power for the active antenna, ensure the receiver supplies the correct voltage according to its specifications. Avoid placing the antenna under thick coverings or inside enclosed compartments that block signals. After installation, verify signal reception and position fix using the receiver’s diagnostics.

Usage recommendations

For optimal performance, place the antenna where it has an unobstructed view of the sky and secure it on a ferrous surface. Regularly inspect the cable and connector for wear or damage, and clean mounting surfaces to maintain good magnetic contact. If installation is permanent, use strain relief on the cable and protect connectors from moisture.
