1. A system comprising:
(a) a main-reflector (104):
(i) having a first parabolic shape (104HP) in a first direction, and
(ii) having a second parabolic shape (104WP) in a second direction, said first shape different from said second shape, said first and second directions orthogonal,
(b) a sub-reflector (102):
(i) having a first concave shape (102HP) in said first direction, and
(c) a feed (100),
said main-reflector and said sub-reflector cooperating to focus an incoming target-beam of radiation on said feed,
wherein said first direction corresponds to an elevation direction and said second direction corresponds to an azimuth direction, wherein said main-reflector first parabolic shape (104HP) has a corresponding first focus (90N) of an incoming target beam, wherein said main-reflector second parabolic shape (104WP) has a corresponding second focus (90C) of an incoming target beam, wherein said sub-reflector (102) concave shape (102HP) is effectively elliptical and in the elevation direction has corresponding third focus (90T) and fourth focus (90G), wherein said feed (100) has a feed horn ISO phase center (90F), wherein said first focus (90N) is coincident with said fourth focus (90G), and wherein said third focus (90T) is coincident with said feed horn ISO phase center (90F).
