Stationary antenna 3284

Stationary antenna 3284

The 3284 stationary antenna with omnidirectional pattern is designed for mobile transceivers which works with the frequency band 400 ÷ 470 MHz.

Antenna advantages:

  • siutable for extreme environmental conditions,
  • long-lasting stability of electrical and mechanical parameters,
  • fiberglass cover gives great resistance to wind and ice,
  • all used materials are galvanically compatible to minimize corrosion,
  • low weight related to its lenght.

Additional equipment 06322/1 mounting holder can be ordered upon request.

Electrical specifications:

Type

collinear, 8 λ dipole
