Stationary antenna 32812

Stationary antenna 32812

The 32812 stationary antenna with omnidirectional radiation pattern is designed to work with base radiotelephones operating in frequency bands 66 ÷ 88 MHz, 118 ÷ 136 MHz, 146 ÷ 174 MHz, 299,5 ÷ 345 MHz, 410 ÷ 470 MHz.

Advantages of the antenna:

  • siutable for extreme environmental conditions, 
  • resistance to vibrations and shocks,
  • long-term stability of electrical and mechanical parameters 
  • dielectric shield,
  • resistance to wind and ice,
  • all used materials are galvanically compatible to minimize corrosion.
