Product Description
The CTi GPS_TRK/SMA Dome Omni-Directional GPS Antenna is a precision electronic component optimized for GPS system integration. This antenna features a dome-shaped physical form and operates at a center frequency of 1575.42MHz, providing excellent coverage for satellite-based location and navigation applications in industrial, embedded, and commercial environments.
The antenna is equipped with an SMA connector for reliable and secure RF interfacing, and employs a magnetic mounting method, enabling easy placement on suitable surfaces within enclosures, vehicles, or equipment racks. Its omni-directional design ensures uniform reception across all directions, enhancing GPS signal reliability even in challenging field locations.
Technical specifications include a passive gain of 3dBi and an integrated filtered Low Noise Amplifier (LNA) offering a nominal gain of 27dB at 5V and a typical noise figure of just 1.5dB, helping to deliver strong, clear signal quality. The antenna boasts a 5MHz bandwidth and supports GPS protocol exclusively. It is supplied with a 100mm lead, allowing greater flexibility for antenna positioning.
The CTi GPS_TRK/SMA is built to IP54 environmental protection standards and complies with RoHS directives for hazardous substances. Its supply voltage ranges from 3V to 5V and it operates with a maximum supply current of 15mA. The impedance is specified at 50 ohms, ensuring compatibility with standard GPS receiver designs.
Common industrial applications include integration in navigation modules, fleet tracking devices, laboratory positioning equipment, telecommunications, and security monitoring systems. The magnetic mount also makes it suitable for vehicular installation and portable deployment scenarios.
This antenna provides robust GPS signal reception for environments demanding real-time position accuracy and system reliability. For more specialized GPS antennas, or to browse other CTi electronic components, visit the GPS Antenna category on EnvMart.
