Dual Frequency Satellite Gnss Antenna U-Ggbg7151

Product DescriptionFeatures1. Using multi feed point design to ensure the superposition of phase center and geometrical center which could minimize the influence of measurement error to lowest range2. High gain of the antenna element and the direction map beam width to make sure the receiving satellites performance of low elevation mask3. Resistance multipath effects board inside could reduce the measurement error caused by multipath4. Water proof, shock proof and lightning resistance ApplicationSurvey antenna is the traditional RTK product standard antenna, can be widely used in land survey, marine survey, channel survey, seismic monitoring, bridge survey, container operation, etc. Detailed Photos SpecificationAntenna Specification    Frequency RangeGPSGLONASSBeidouGalileoL1/L2G1/G2B1/B2/B3E1 E2bGain at ZenithL1≥5.5dBiG1≥5.0dBiB1≥5.0dBi E1≥5.0dBiL2≥5.0dBiG2≥5.0dBiB2≥5.0dBiE2b≥4.5dBi  B3≥4.5dBi PolarizationRHCPAzimuth Coverage360oImpedance50ΩOutput VSWR≤1.5Axial Ratio≤3dBPhase Center Error
