M.E.C.’s C390-310 has a broadband sectoral horn design, which operates from 18 to 40 GHz.  The antenna has an end launch K-connector, which minimizes the overall width of the antenna.  This particular configuration makes the C390-310 very suitable for interferometer array applications where small distance between antenna elements is required.  The C390-310 also has a polarizer providing slant-linear polarization.
