Abstract
A versatile dual band satellite system includes a main conductive mounting plate member with a central opening of a predetermined size, and a KU band pick-up unit mounted in the plate to face a satellite antenna. A dielectric funnel support is mounted on the side of the mounting plate toward the antenna, and includes a central opening of the same size as that in the mounting plate, for receiving a C-band pick-up unit. The system includes appropriate microwave chokes and microwave impedance-matching structure, to improve the rejection of spurious or off-axis signals, and to maximize signal strength at the input of both the KU band and the C-band units. With the mounting openings in the main mounting member and in the dielectric funnel support being identical, full interchangeability of parts is practical, and an initial installation may include the C-band unit mounted in the mounting plate to face the antenna.
