Feature:1. The antenna adopts a single-layer multi-feedpoint ultra-wideband design, so that the phase center elevation difference is the smallest in the entire working frequency band.2. The antenna unit has high gain and small gain roll-off, and has good reception effect on satellite signals with low elevation angles, ensuring that the satellite can still be normally collected in some occasions where the occlusion is severe.3. Low noise amplifier uses pre-filtering technology to effectively suppress out-of-band interference signals and improve system reliability.4. Reactive network suppression technology effectively reduces the impact of multipath signals on measurement accuracy.5. The waterproof and UV-resistant cover provides a guarantee for the antenna to work in the field for a long time.6. The external full-band GNSS measuring antenna supports satellite navigation signal reception of Beidou II, GPS and GLONASS systems, and meets the needs of current multi-system compatibility and high-accuracy measurement. It can be widely used in geodesy, ocean measurement, agriculture, and deformation. Monitoring and other high-accuracy navigation and positioning occasions.Specification:Item Type:Antenna ReceiverSupported Satellite SignalBDS: B1, B2, B3;GPS: L1, L2, L5;GLONASS: G1, G2, G3:Galilco: El, E2, E5a, E5b, E6, L-BandWorking Frequency Band: 1154MHz-1300MHz; 1551MHz-1615MHzImpedance Matching: 50 OhmsPolarization Mode: Right Circular PolarizationAntenna Shaft Ratio: 3dBHorizontal Coverage Angle: 360 DegreesPhase Center Error: 2.0mmLow Noise Amplifier Gain: 402dBNoise Figure: 2.0dBOutput Standing Wave Ratio: <2.0:1In-Band Flatness: 2dBWorking Voltage: 3.0~16VDCWorking Current: 35mAWorking Temperature: -40C~+80CStorage Temperature: -45C~+85CHumidity: 95% Non-CondensingProtection Level : IP67Antenna Size : 152 x 67.9mm / 5.98 x 2.67inOutput Interface : TNCWeight: 430g/15.17oz.Package List:1 x Receiving Module1 x Base1 x 3 meters Feeder
