Transmitting Antennas
General. The FL 4BB N Directional Antenna is designed for low power transmissions in FM Broadcast Band (87,5 –108 MHz). This antenna is made with non-corrosive aluminium alloy and composed of four elements and a mounting bracket.
Effective cost. Good performances at effective cost is the main feature of this antenna.
Broadband. Suitable for channel or broadband operations with multi-channel combiners.
Horizontal or Vertical polarization are possible with the standard mounting brackets.
Instant installation. The reduced overall dimensions and the low weight permit an easy installation even on light poles.
Disassemblable. This antenna is disassemblable in order to reduce the shipment and stocking costs.
Lightning resistance is guaranteed by the DC ground potential of the entire antenna.
