1. A signal receiving system comprising:
- an input assembly comprising a plurality of sectors wherein each of the sectors has at least two inputs;
a plurality of signal processors wherein each signal processor is connected to an input to receive a signal from that input and wherein the signal processors should be maintained at specified environmental conditions for optimum signal processor performance; and
a plurality of environmental maintenance units wherein each of the units maintains at least two of the signal processors at the specified environmental conditions for optimum performance of the signal processors;
wherein an environmental maintenance unit for a signal processor connected to an input in a sector does not maintain all signal processors connected to all inputs in that sector;
a first signal from a signal processor connected to a first input in one of the sectors and a second signal from a signal processor connected to a second input from that sector are sent to a receiver; and
the receiver outputs a third signal based on the first and the second signal.

Abstract
A signal receiving system has an antenna assembly divided into sectors. Each sector employs diversity by having at least two antennae for receiving signals from that sector. Signals from the antennae are passed to filters where the filters contain superconductors requiring cooling. The filters are housed in cryocoolers in a manner such that no cryocooler contains more than one filter receiving signals from a given sector. After filtering, the signals are sent to diversity receivers which combine or compare signals from antennae in the same sector.
