1575 Mhz GPS GNSS Magnetic Mount Antenna 1 Meter Cable Length

1575 Mhz GPS GNSS Magnetic Mount Antenna 1 Meter Cable Length provides high-gain satellite signal reception for navigation systems and tracking hardware requiring superior sensitivity in the L1 band. This active antenna utilizes a high-performance ceramic patch element coupled with a low-noise amplifier (LNA) to pull in weak signals from GPS and GNSS constellations. Furthermore, the integrated magnetic base allows for instantaneous mounting on any metallic surface, making it an ideal solution for vehicular testing and outdoor telemetry. Consequently, users can achieve faster time-to-first-fix (TTFF) and maintain a stable position lock even in challenging environments with partial sky obstruction. Therefore, you should choose this antenna to upgrade the reception quality of your GPS modules, asset trackers, or marine navigation equipment.

Key Features:

• High-Gain Active LNA: The internal low-noise amplifier boosts incoming signals to compensate for cable loss, ensuring the receiver gets a clean, strong signal.
• Magnetic Mounting: A powerful integrated magnet resides in the base, allowing for secure attachment to car roofs or metal enclosures without drilling.
• Weatherproof Housing: The rugged plastic casing protects the internal electronics from moisture and UV exposure during long-term outdoor use.
• Universal Compatibility: This antenna works seamlessly with most GPS/GNSS modules that provide a 3V to 5V DC bias on the antenna port.
• Optimized 1575.42 MHz Tuning: Precision tuning for the GPS L1 band maximizes signal-to-noise ratios (SNR) for higher accuracy.
