High-Sensitivity Waterproof GPS Antenna for Professional Tracking and Navigation Applications
This waterproof active GPS antenna is a high-performance navigation solution designed for professional tracking and IoT applications. Featuring an integrated low-noise amplifier (LNA) with 28dB gain and right-hand circular polarization (RHCP), it delivers exceptional GPS L1 band (1575.42MHz) reception even in challenging environments. The antenna comes with both adhesive and magnetic mounting options, a 3-meter RG174 cable, and a 15cm RG178 coaxial pigtail with SMA male connector for easy integration. With an IP67 waterproof rating and operating temperature range of -40℃ to +65℃, it is ideal for vehicle telematics, industrial IoT, and mobile tracking systems where reliability is critical.
