Disclosed are a transmitting device and receiving device for selecting a transmit channel in a wideband high frequency wireless system using a plurality of transmit antennas, and a method thereof. According to the method of selecting a transmit channel, data is transmitted to the receiving device via a predetermined first antenna, and a first channel probing response message including first channel status information of the first antenna is received, in response to the transmission of the data. A channel probing request message that request channel status information of a second antenna, is transmitted to the receiving device via the second antenna, and a second channel probing response message including the second channel status information of the second antenna is received in response to the channel probing request message.
