ABSTRACT:
A radio communication device capable of specifying an arbitrary antenna gain even when an antenna having such an arbitrary antenna gain is connected is configured as follows. The radio communication device includes: a first connector for connecting a first antenna having any given antenna gain; a second antenna having a known antenna gain; a reception circuit receiving radio waves; and a control circuit that specifies a relative antenna gain of the first antenna with respect to the second antenna using a first intensity of radio waves received by the reception circuit using the first antenna connected to the first connector and a second intensity of radio waves received by the reception circuit using the second antenna, and controls the reception circuit based on a third intensity of radio waves corrected from the first intensity of radio waves based on the relative antenna gain.
