ABSTRACT:
Portable antenna test apparatus has a test set positioned a determined distance from a number of antennas of an aircraft. A transmitting module of the test set contains low frequency, mid frequency, and high frequency antennas connected to a radio receiver and power amplifier in and of the test set for receiving control commands and for transmitting a number of simultaneous test signals to the number of antennas in the aircraft. A signal generator produces low frequency, mid frequency and high frequency signals. A hand-held computer is connected to a communications radio in and of the aircraft via a radio interface adapter of the hand-held computer and a control computer is connected to the signal generator. The hand-held computer transmits commands via the aircraft radio, which commands are received by the receiver in the transmitting module. This receiver conveys the commands to the control computer which then programs the signal generator. By this means, an operator in the aircraft cockpit remotely controls the signal generator.
