VLG - Dual band car antenna Adopted multi-feed point and completely symmetrical structure, which lower the influence of antenna to measurement error while surveying.Antenna has high Gain, with pattern wide beam, with good reception with low elevation signal, insure the normal satellite signal reception even in serious occlusion environment.The Low noise amplifier section adopted pre-filtering scheme to effectively suppress out-of-band interference and improve the reliability of the system.
This is a high precision car antenna covered GPS L1/L5, BDS 2nd generation B1/ B2, GLONASS L1, it can meet the request of multi-system compatible and high precision measuring from GNSS surveying equipment. It is widely be used in Geodesy and mapping, Marine survey, Geological deformation monitoring and other filed.
