With the compact polycarbonate radome enclosure and the waterproof/weatherproof physical construction, SA-300 is deliberately designed for both navigators and researchers who often need to use GPS in harsh environments, such as strong shock or vibration, fierce wind, and even continuous exposure to water and sunlight.
Additionally, SA-300's stainless pole mount not only enables the antenna to receive GPS signals steadfastly, but also enables the cable to be threaded, protecting itself from environmental damage. Both of the industrial standard TNC connector and 1¡¨-14 straight thread perfectly fit the typical marine mount, enhancing multifunction and application for SA-300. Furthermore, through the inventive integration of dual amplifiers and dual filters (saw filter + bandpass filter), SA-300 provides excellent resistance to RF signal interference without compromising its gain, which helps ensure stable performance even in RF signal-jamming environment.
Features
A-300 is an active GPS antenna with high gain of 27 dB and low current of 27mA, supporting RG-58 A/U cable as long as 50m.
Given the aforementioned features, we believe SA-300 to be your most reliable companion for timing, stationary and marine application
