Miniaturized three-system seven-frequency measuring Antenna specification
Production specification：
Product name ：Miniaturized three-system seven-frequency measuring Antenna specification
Frequency range ：GPS L1/L2、GLONASS L1/L2、BDS B1/B2/B3
Product application：
This antenna is a miniaturized three-system seven-frequency measurement antenna covering GPS L1/L2, GLONASS L1/L2 and BDS B1/B2/B3, meeting the requirements of multi-system compatibility and high-precision measurement of current measurement equipment. It can be widely used in geodetic surveying, ocean surveying, hydrographic surveying, dredging surveying, seismic monitoring, landslide monitoring, bridge deformation monitoring, container operation at shanwharf, etc.
Product description:
1. The antenna part adopts multi-feed point design and a completely symmetrical antenna structure to realize the coincidence of phase center and geometric center and reduce the influence of the antenna on the measurement error;
2. With high antenna gain and wide beam width, the antenna can receive low-elevation signals well, ensuring that satellite signals can be normally received in some occasions with severe occlusion;
3. The low-noise discharge part adopts the prefilter scheme, which can effectively suppress the strong interference signal outside the band, avoid saturation of the amplifier and improve the reliability of the system;
4. Built-in voltage stabilizing circuit can work normally in a wide input voltage range.
Install instruction：
1. Metal nut inserts are set at the bottom of the antenna, and the butt thread 5/8" -11unc is connected and fixed with the carrier;
2. Rf interface is TNC-k rf coaxial connector.
