M.E.C.’s wide flare corrugated conical horn antennas produce nearly constant and equal E and H-plane beamwidths over broad frequency bands. Beamwidths can range from 20 to 70 degrees. These units also feature very low side and cross polarized lobes and low internal losses.

M.E.C.’s narrow flare corrugated conical horn produces frequency dependent, equal E and H-plane beamwidths over an octave beamwidth. Beamwidths can range from 7 to 40 degrees.

The corrugations in these horns modify wall impedance to excite a hybrid mode (HE11) and produce an aperture field nearly identical in all planes. Due to their circular symmetry, these horns support any polarization.
