Stationary antenna 32820

The 32820 stationary antenna  with omnidirectional radiation pattern is designed to work with base radiotelephones operating in frequency band 380÷470 MHz.

Advantages of the antenna:

  • suitable for use in extreme environmental conditions, 
  • long-term stability of electrical and mechanical parameters,
  • fibreglass cover provides resistance to wind and ice,
  • low weight related to its length.
