Removable mold for forming high frequency antennas

摘要

A removable mold for forming high frequency antennae, such as a horn-reflector antenna. The removable mold may comprise a paraboloid-cylindrical section and a pair of half cone shells for forming respectively the paraboloid-cylindrical portion and the cone portion of the antenna. In assembling the mold, the shells are secured together and then the cylindrical section is fastened to the assembled shells. After the antenna has been formed, the mold is disassembled by first removing the paraboloid-cylindrical section, thereafter removing one of the shells and then the remaining shell; and all such mold parts being removed via the radiating aperture of the paraboloid-cylindrical portion of the antenna.
