Product Description:
Ø The antenna consists of 6 anti-jam units and 1 high-precision unit, providing high-precision positioning and anti-jam functions.
Ø The anti-jam antenna unit adopts a double-feed symmetrical design to ensure the performance consistency of each unit.
Ø The high-precision antenna unit adopts a four-feed point design, with stable phase center and high positioning accuracy.
Ø Equipped with a breathing valve to ensure the balance of internal and external air pressure when the antenna is working.
Ø The core unit and components are completely sealed to IP67 waterproof level, ensuring normal operation in complex outdoor environments for many years.
