We have had this aluminum parabolic reflector manufactured by a local sheet-metal shop for the last 8 years. They use our own parabolic die to roll these reflectors. This reflector should be useful from about 5 ghz (lower frequencies would not have much gain) through 40 ghz (surface smoothness becomes the limiting factor here). These reflectors have a sturdy 1/2" rolled edge that almost curls back on itself in the rear of the dish, for strength. There is no mounting hardware or accessories included. This is the reflector only. These dishes are about 12 inches (30 cm) in diameter, and made of .09" (2mm) thick aluminum. They weigh 15.5 oz (0.44 Kg) each. The focal length is 7.2 inches (18 cm) so it is easy to illuminate with a splash feed or horn. Each reflector costs $US25 each, and we can send them almost anywhere at low cost.
