Sirio SD-FM Dipole 87-194 Mhz VHF Base Station Antenna

Dipole base station antenna working on 87 - 194 Mhz by cutting. Optimized for vertical polarization it can be also placed in horizontal polarization. The elements are fixed to the boom by a strong die-cast metal support to get the maximum strength. All connections are waterproof and it is supplied with UHF female connector. To inprove the antenna gain please install it in stacked or bayed array.

Features:

Base station antenna, Mono-band
Unity-gain, Horizontal or Vertical polarization
Directional (if Horizontal) or Omnidirectional (if Vertical)
Made of aluminium alloy 6063 T-832
