Abstract:
1. A receiver for intercepting a modulated radio signal in a first mode or and second mode, the receiver comprising: first and second antennas having different directionality to produce corresponding first and second input signals; means for evaluating the quality of the first and second input signals; first and second signal processors connected to the one or both of the first and second antennas for demodulating the respective first and second input signals; a tuner in each of the first and second signal processors, the tuners being set to different frequencies in the first mode and the same frequency in the second mode; a utilization circuit; means in the first mode for connecting both of the signal processors to the utilization circuit irrespective of the quality of the input signals; and means responsive to the evaluating means in the second mode for connecting one of the signal processors to the utilization circuit based on the quality of the input signals, the first and second modes operating alternatively.
