A feed horn and systems and methods of making and using the feed horn are presented. Exemplary feed horns include a first portion comprising a dual mode geometry and a second portion comprising an axial corrugation geometry. The feed horn may operate simultaneously in a plurality of separate frequency bands (e.g., from about 18.3 GHz to about 20.2 GHz and from about 29.1 GHz to about 30.0 GHz) and a plurality of separate waveguide modes (e.g., TE, TMor HEmodes); simultaneously operating over two bandwidth segments of at least 1900 MHz that are separated by at least 5000 MHz. The feed horn may have a short axial length (e.g. less than 4 wavelengths at 18.3 GHz), and it may be configured to operate in a prime fed offset reflector antenna system. In addition, the feed horn may be formed as a single piece via a single casting pull.

An antenna radiator is provided. The radiator includes four elements, each including a node, a first ring connected to the node, and a second ring connected to the node and disposed inside of and coplanar with the first ring. The first ring includes a first plurality of segments, and the second ring includes a second plurality of segments.

In an exemplary embodiment, a dual-band four-port orthomode transducer (OMT) is molded or cast. The OMT may be external to a transceiver housing or included as an integrated portion of the transceiver housing or a drop-in module. In an exemplary embodiment, a four-port OMT is formed from two pieces, the two pieces having a joint adjacent to or aligned to the axis of the common port. In an exemplary embodiment, the OMT is substantially planar and formed of a split-block embodiment. The two OMT pieces are joined and held together with a plurality of discrete fasteners. Furthermore, the OMT is configured to switch polarizations. The polarization switching is initiated using a remote signal and can facilitate load balancing.
