1. AT-700 is an external full-band GNSS mitting antenna that supports satellite navigation signals of BeiDou II, GPS, GLONASS and systems as well as differential L-band. 2. The antenna adopts a multi-feed point design to make its phase center stable; the antenna unit has high gain, wide beam width and small gain roll-off; the triple-proof cover provides protection for the antenna to work in for a long time. 3. Comprehensive Satellite Compatibility: Designed to support a wide range of satellite systems including GPS (L1, L2, L5), Beidou, Glonass, and . This versatility ensures reliable performance across different geographic locations and applications. 4. Optimized for RTK Systems: The AT-700 is specifically engineered for Real Time Kinematic (RTK) indoor repeaters, enhancing signal accuracy and stability for critical positioning needs. 5. and High Performance: Built to withstand various environmental conditions, ensuring consistent and uninterrupted service. Its passive design means no need for external power, making it easy to integrate into existing setups. Support satellite signals: B1, B2, B3; L1, L2, L5; G1, G2, G3; El, E2, E5a, E5b, E6 L-Band Working frequency band: 1154MHz-1621MHz Impedance matching: 50 ohms Working temperature: -40-+80 Polarization: right-hand circular polarization Storage temperature: -45-+85 Antenna axial ratio: 3dB Humidity: 95% non-condensing Horizontal coverage angle: 360 Protection level: IP67 Passive maximum gain: 4.5dBic Phase center error: 2.0mm Output interface: TNC Output standing wave ratio: Less than 2.0:1 Fixed connector: 5/8-11 American In-band flatness: 2dB Colour:White Material:ABS Due to different batches, there may be differences in product appearance and printed text, which not affect use Package Contents: 1 * AT-700 GNSS Passive Antenna Only the above package content, other products are not included.
