Antenna reflector construction

Claim 1

IN AN ANTENNA SYSTEM HAVING A MOUNT, A LARGEDIAMETER REFLECTOR ROTATABLY SUPPORTED RELATIVE TO SAID MOUNT, AND COMPRISING: (A) A UNITARY SHELL HAVING A PARABOLIC REFLECTING SURFACE AND ESSENTIALLY COMPRISED OF PARABOLIC REFLECTOR PANELS JOINED TOGETHER IN HOOP COMPRESSION, (B) A MAIN RING BEAM MEANS LOCATED CONCENTRICALLY WITH RESPECT TO SAID UNITARY SHELL AND AT A MID-WAY POSITION IN THE RADIAL EXTENT OF SAID UNITARY SHELL REFLECTING SURFACE, (C) FIRST CONNECTOR MEANS WHICH ARE FASTENED TO SAID UNITARY SHELL AND TO SAID MAIN SHELL RING BEAM MEANS, WHICH TRANSFER SUBSTANTIALLY THE ENTIRE WEIGHT OF SAID UNITARY SHELL INTO SAID MAIN RING BEAM MEANS WHEN THE REFLECTOR IS IN A GENERALLY HORIZONTAL POSITION, AND WHICH PERMIT PORTIONS OF SAID UNITARY SHELL TO MOVE RELATIVE TO SAID MAIN RING BEAM MEANS IN DIRECTIONS GENERALLY NORMAL TO THE REFLECTOR RADIO FREQUENCY AXIS WHEN THE REFLECTOR IS ROTATED TO A GENERALLY VERTICAL POSITION, (D) OTHER RING BEAM MEANS SUPPORTED BY AND LOCATED RADIALLY OUTWARDLY AND RADIALLY INWARDLY RELATIVE TO SAID MAIN RING BEAM MEANS AND EACH COMPRISED OF SPACED-APART TUBULAR UPPER AND LOWER CAP MEMBERS WHICH CONSTITUTE CHORDS OF A CIRCLE, CIRCUMFERENTIALLY SPACED-APART TUBULAR STRUT MEMBERS CONNECTED TO SAID UPPER AND LOWER CAP MEMBERS TO MAINTAIN SAID CAP MEMBERS IN SPACED-APART RELATION WITH RESPECT TO EACH OTHER ALONG A DIRECTION PARALLEL TO THE REFLECTOR RADIO FREQUENCY AXIS, AND TENSION MEANS CONNECTED TO SAID UPPER AND LOWER CAP MEMBERS INTERMEDIATE SAID STRUT MEMBERS TO PLACE ALL OF SAID MEMBERS IN EACH OF SAID OTHER RING BEAM MEANS IN COMPRESSION LOADING, AND (E) SECOND CONNECTOR MEANS FASTENED TO SAID UNITARY SHELL AND TO EACH OF SAID OTHER RING BEAM MEANS ADJACENT SAID UPPER CAP MEMBERS, SAID OTHER RING BEAM MEANS AND SAID SECOND CONNECTOR MEANS RESTRICTING MOVEMENT OF ADJACENT PORTIONS OF SAID UNITARY SHELL IN DIRECTIONS PARALLEL TO THE REFLECTOR RADIO FREQUENCY AXIS WHEN SUCH PORTIONS MOVE RELATIVE TO SAID OTHER RING BEAM MEANS IN DIRECTIONS GENERALLY NORMAL TO THE REFLECTOR RADIO FREQUENCY AXIS IS AS THE REFLECTOR IS ROTATED TO A VERTICAL POSITION.
