PROBLEM TO BE SOLVED: To provide a supporting method and its system for setting an antenna direction to maximize the strength of a signal received by the antenna. SOLUTION: The system is provided with an instruction device 50 emitting a command signal, a reception signal from an antenna is received via a low noise block(LNB) 44 at each of a plurality of directional positions, a reception signal strength at each of a plurality of the directive positions is measured with a reception signal strength indicator(RSSI) detector 72 to energize the instruction device 50 to emit an instruction signal corresponding to each of a plurality of the directive positions, and a frequency of the instruction signal is changed nonlinearly with the signal strength, and when the strength of the signal is increased, the difference between the instruction signal frequencies is continuously increased. |
