A control method for a high-frequency radio equipment and a high-frequency radio equipment system in spread spectrum radio data communication are provided which are interference-tolerant and can maintain transmission quality with improved receiving sensitivity. A high-frequency radio equipment system provided with, in a base station, an antenna part comprised by a plurality of antennas, a radio part for amplifying a received signal, band-limiting and down-converting it to an intermediate frequency, a signal processing part for carrier-demodulating the signal inputted from the radio part, demodulating the signal which was despread-spectrum processed and synchronized and decoding the received data, an antenna control part for determining a code error rate for the received data inputted from the signal processing part, forming an appropriate antenna pattern based on the error rate and outputting a signal for controlling an antenna switching part according to the information of the antenna pattern.
