Compact & Sensitive GPS Antenna with 
Excellent Signal Amplification for Mobile Applications

SM-19 is an externally mounted GPS antenna that provides continuous L1 band with high gain and low power consumption to a wide selection of GPS receivers in today's market. It is the integration of a high-performance GPS patch antenna and a low noise amplifier into a low profile, extremely compact and fully waterproof enclosure. SM-19 provides excellent signal amplification to any GPS receiver with 2.5~3.3V DC antenna power at the center pin. Coming with small size and ruggedness, SM-19 is designed mainly to meet the robust demand for a GPS antenna that can maintain GPS signal stability for automatic vehicle locating and navigation even in a harsh environment.
