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.
