AT340 Geodetic Antenna
AT340 Geodetic Antenna
Description
The AT340 is a super performance GNSS Antenna that can track
GPS, GLONASS, BeiDou, Galileo, L-Band and SBAS. Its high gain
and wide beam provide good signal tracking performance even
satellites at low elevation angle. It is a good choice for customers to
develop systems or solutions for land survey, agriculture, construction
and deformation monitoring.
Features
- Support GPS L1/L2/L5, GLONASS L1/L2 and BeiDou
B1/B2/B3 Galileo E1/E5a/E5b/AltBoc, L-Band and SBAS - Multi-feed design provides stable phase center and
multipath rejection capability - Its high gain and wide beam width provide good signal
tracking performance when satellites are at low
elevation angle - Water-proof and dust-proof design ensures absolute
seal of kernel parts, capable for work in harsh
environment - Lightning proof circuit inside protects the LNA from
surge immunity
