12 .4 – 140 GHz, Prime Focus Antennas

Diameters from 18 to 72 inches


Mi-Wave’s 202,203 Series prime focus antennas consist of a parabolic reflector, a linearly-polarized primary feed, and a feed support assembly, that is attached to the rim of the reflector in order to position the feed accurately. Tapped holes are provided on each antenna for mounting. For applications that require larger diameters, the 203 Series prime focus antennas feature metalized fiberglass reflectors and cover a frequency range from 12 .4 to 140 GHz . They are available in diameters from 18 to 72 inches with low surface tolerances (typically 0 .0023 inch RMS.
