Circularly Polarized Quad-Ridge Horn Antennas

M.E.C.’s 3:1 bandwidth horn series are quad-ridge designs which offer both symmetrical and asymmetrical beam coverage in azimuth and elevation planes.  The lens-horn version utilizes a pair of dielectric lenses to broaden the beam width in one particular plane (i.e. the azimuth plane) and to control off-axis axial ratios.

All units offer low VSWR, high power handling capability, compact size, and are suitable for airborne ECM applications.

Both waveguide and coaxial input versions are available.

  • Compact Size
  • Circularly Polarized
  • Low Axial Ratio
