A main control unit in a radio reception apparatus selects from an adaptive array reception mode and a single route reception mode, in accordance with a prescribed condition. A storage unit is provided with a plurality of storage location lengths. The beam steering function is implemented with a hardware architecture where the phase shifters are built-in ahead of the power amplifiers such that these low power phase shifters impart phase delays to low power signals without wasting RF signal power and hence improving efficiency. However, other arrangements are possible without departing from the scope of the invention.
