MES 63525 GPN Grid Parabolic Antenna consist of a parabolic shaped reflector spun from a sheet of aluminium. The parabolic shape focuses energy at the feed point of the antenna. These parabolic Antennas have a narrow focused beam of energy and relatively high gain compared to many other types of antennas. These antennas will have a mounting system to attach theantenna to a pipe, tower leg andor a specific radio in some cases.
