Abstract
A horn feed including: a central conduit extending axially in a first direction from a first portion that is configured to be relatively distal from a sub-reflector and including a first aperture and a second portion that is configured to be relatively proximal to the sub-reflector and including a second aperture; and an interface configured to connect to a dielectric support including an outer cylindrical dielectric wall of a substantially cylindrical shape and an inner cylindrical dielectric wall of a substantially cylindrical shape, wherein the central conduit, the outer cylindrical dielectric wall and the inner cylindrical dielectric wall are co-axial.
