Product description
Product parameters

Its high gain and wide beam provide good signal tracking performance even when satellites at low elevation angle. It is a good choice to customers developing systems or solutions for land survey, agriculture, construction, deformation monitoring.

 

Features

 

 

  • Multi-feed design provides stable phase center and multipath rejection capability
  • Good signal tracking performance when satellites at low elevation angle
  • Water and dust-proof design ensure absolute seal of kernel parts
  • Lightning proof circuit inside protects the LNA from surge immunity
