Corrugated feeds from ASYSOL are based on open-ended circular waveguide with several frontal corrugations. As a result of optimized design and high-precision manufacturing, the feeds possess rotationally symmetric radiation pattern with low back radiation and very low cross-polarization. In standard single-polarization configuration, the feeds are provided with integrated waveguide-to-coax adapters with SMA or K connector. In dual-polarization configuration, the feeds are provided with Ortho-Mode Transducers with very low cross-coupling. In both singlepol and dual-pol configurations, the feeds cover a standard waveguide band.
