Circularly Polarized Horn Antennas

M.E.C.’s circularly polarized horn antennas offer frequency coverage of an octave or more with symmetrical E and H-Plane beamwidths. Standard gain units (9 dBi) have a nominal beamwidth of 60° and incorporate a hemispherical fiberglass radome. High gain units (15 dBi) have a conical  flare to increase the gain 6 dB, hence the nominal beamwidth is 30°. All types are pressurized to 15 psig.

All units offer lower VSWR, high power handling and are suitable for military airborne applications.

Narrow band units with improved VSWR and axial ratio can be supplied. Broader bandwidths and other lengths are also available on request.

Linearly Polarized Horn Antennas

M.E.C. offers several types of linearly polarized horn antennas covering bandwidths of an octave of more with your choice of waveguide or coaxial inputs.  Construction is aluminum with chromate conversion finish per MIL-C-5541, Class 3, and epoxy enamel paint.  Typical examples are listed below. Other frequency bands and various input connectors may be specified.
