1. In a microwave receiving/transmitting earth station of the type having a reflector dish in a shape concentrating intercepted rays of a microwave signal beam at a focal point on the axis of the dish, a feed horn located thereat and the dish being alternatively adapted to emit a beam of microwave signals supplied to the feed horn located at the focal point, together with means connecting the feed horn to a utilization device/source of microwaves;

  • the combination of;

    (a) a layer of thin, microwave reflective material forming said reflector dish, said dish having a front and a back;

    (b) a first mass of material substantially transparent to said microwave beam and having a discrete surface portion in a shape matching said front of said layer of thin microwave reflective material layer, said first mass projecting beyond said focal point by an amount sufficient to encompass said feed horn and thereby provide the sole support therefor and spacing thereof from said dish;

    (c) a second mass of said transparent material, said second mass having a particular surface portion in a shape matching said back of the dish; and

    (d) means integrating said layer, said first mass of transparent material, and said second mass of transparent material into a composite unit having said layer reinforcedly supported between said first and second masses.
