摘要： A moveable antenna system with a position sensor circuit and a circuit which transmits the position sensing data and the radio frequency (RF) on the same wire. The position sensor comprises a sensing pin and a sense track concentric with the coaxial cable for the RF signal. When the antenna is in the preferred position for transmission, the sensing pin is in contact with the sense track, thus closing a switch, allowing the unit to transmit RF signals. Otherwise, the sensing pin is not in contact with the sense track, preventing any transmission of data. The signal that results from the opening and closing of the switch is carried on the same transmission line as the RF signal. This is accomplished by using capacitors to block direct current (DC) from the transmission line and using resistors and shunt capacitors to prevent any leakage of RF signals onto the sensing circuit.
