Summary

Description
English: A monopole corner reflector antenna for military communication from a US Navy communications manual. The corner reflector antenna is a moderate gain directional antenna invented by John D. Kraus in 1938. Dipole corner reflector antennas are widely used as rooftop UHF television antennas and for data communication links, but vertical monopole versions like this can be used as directional antennas on the MF and HF bands. The antenna consists of a vertical wire quarter-wave monopole driven element in front of two reflecting screens at a 90° angle, consisting of "curtains" of parallel wires suspended from a support cable. The radiating element is attached to a feedline at its bottom. The other side of the feedine is connected to a ground system of buried cables in front of the antenna. The quarter wavelength driven element, together with its reflection in the ground plane, form a half-wave dipole.
