GPS Timing Antenna Marine Antenna 32dBi
Product Introduction
This antenna has the following features:
Supports coverage of the GPS L1 frequency band and GLONASS L1 frequency band, and is suitable for receiving satellite signals in these two frequency bands.
The antenna unit has high gain and is capable of receiving weaker signals. The pattern beam is wide and can receive a wide range of signals. It has good signal reception ability at low elevation angles and can receive satellite signals at low altitudes.
The combined feed design is adopted to ensure that the phase center of the antenna coincides with the geometric center to improve positioning accuracy.
It can be used with various satellite navigation terminal equipment to provide users with high-precision positioning services.
