SBB-EP Series
Band IV/V (UHF) Antenna 470-700 MHz

The SBB-EP series of antennas are slot broadband-elliptical polarized with dual inputs on each slot; low wind load antennas designed as interim, permanent reseve or main antenna.
The SBB-EP is ideally suited to the broadcaster who requires a high performance antenna with frequency agility to allow for both current and future channel operation. Used by a single broadcaster, or multiple broadcasters as a shared antenna, SBB antennas provide unprecedented broadband performance.
SBB-EP antennas are available 8, 16 and 24 slots high and with Cardioid 'C160' , Cardioid 'C170' or Skull 'S180' patterns. See external document attached for details.

FEATURES / BENEFITS

  • Full broadband performance 470-700 MHz for future and current channel allocations.
  • Corrosion resistant construction with cylindrical fibreglass radome.
  • Extremely low wind loading.
  • High power rating.
  • Supplied with brackets for side mounting.
  • For detailed technical and mechanical information click the external document link on Sheet 2.
  • Broadband constant power ratio between horizontal and vertical polarizations.
  • Power ratio (typical) 30% V / 100% H
