描述

  • The antenna structure is small and the installation method is flexible, which can effectively reduce the difficulty of installation by construction personnel.
  • The antenna gain is high, the pattern beam is wide, and the reception effect of low-elevation signals is good, ensuring that the satellite can be received normally in some severely obstructed occasions.
  • Designed with a lightning protection circuit, which can effectively avoid equipment damage caused by lightning strikes, especially suitable for power systems and communication systems.
  • 4. Equipped with high out-of-band suppression low-noise amplifier circuit, with strong anti-interference ability, can be used in environments with harsh electromagnetic environments, such as environments under high-voltage lines.

    • Application

    It can be widely used in communication base stations, power systems and other fields.
