Ask a question To order

Purpose

  • Tx/Rx antenna that operates in a frequency range from 100 to 400 MHz.
  • Provides omnidirectional radiation in the horizontal plane.

Features

  • The antenna can be set on the masts, special radio-transmitting towers, etc.
  • The design ensures small wind load and weight.
  • The configuration minimizes the influence of mismatching characteristics and ensures lightning protection.

AR-100A antennas can be used in air navigation, shipboard communication, ground communication and so on.
