High Performance Antennas
High Performance antennas are formed of aluminum, which is spun to precise tolerances. Then a shroud is also fabricated of aluminum and fitted with a planar radome to protect the feed and provide for a significant reduction in side lobes. Often manufacturers will utilize absorber material to improve the pattern performance of the side lobes and front-to-back ratio. The exception is the DicriminatorTM series from Radio Waves, which utilizes a molded plastic reflector that is shaped for optimum side lobe performance.
