摘要
A low-cost, essentially self-contained microwave earth station having a reflector dish together with the microwave sensing/emitting elements embedded in a rigid, low density and low thermal conductivity plastic foam. At least the sides and back of the unit may be encased in a fiberglass-resin shell. Shielding for terrestrial interference also may be present. For a receive-only station, a low noise amplifier together with frequency conversion and channel selection (or all-channel transmission) to circuits may also be embedded in the foam. The only connections to such a receive-only unit are a line from a d-c source of power for supplying the required operating voltages to the electronics, and a coaxial cable supplying the selected one of the received information signals to the TV display or other device utilizing those signals. Preferably, a single coaxial line with the dual function of information output and d-c power input is employed.
