AS-48989-01 Biconical Omnidirectional Antenna

The polarization is “slant linear”, allowing reception of circular, vertically, and horizontally polarized signals from a single connector. This antenna combines broadband frequency coverage with excellent performance features for an antenna of small physical size. These features include low deviation from omni and excellent response to vertical/horizontal polarization signals. The AS-48989-01 is readily adapted to numerous applications including airborne, ship, vehicle and fixed site requirements. This model is an improved, form/fit/function, version of the previous AS-48977 Omni Antenna.

Features:

  • Broad Frequency Band
  • Slant Linear Polarization
  • Exceptional Azimuth Ripple
  • Rugged Construction Suitable for Airborne Applications
