ABSTRACT:
An antenna system particularly suitable for use with a satellite in a terrestrial communication system includes first and second signal reflectors which are selectively positionable with respect to an RF signal feed whereby first and second target areas can be serviced. A support structure is provided for the reflectors whereby the first and second reflectors are rotated into operating positions with respect the RF signal feed. The support structure further includes a hinge for supporting the first reflector whereby the reflector can be rotated between an operating position and a stow position. The support structure further includes a second gimbal which allows the second reflector to independently rotate to a flipped position and then pivot to the stow position adjacent to the first reflector with the concave surfaces of the two reflectors in a stacked position.
