摘要： An antenna latching mechanism includes a housing with an attached antenna and a mating utility part. A collar is formed on one of the housing and the utility part and a mating stem, rotatably fitting within the collar, is formed on the other. The collar and stem define an opening and a ridge is formed in the opening. Flexible fingers, each having a cam surface, are positioned on one of the housing and the utility part to extend through the opening, with the stem coaxially positioned in the collar, so the cam surfaces engage the ridge in a releasable assembled orientation. Detent notches are defined in one of the collar and stem and a mating flexible detent finger is formed in the other to engage a selected one of the notches and provide a plurality of stable axial positions of the housing relative to the mating utility part.

摘要： A dual-frequency conformal multi-filiar helical antenna system (20) provides a low-profile, low drag antenna useable in flying equipment. This antenna system (20) securely holds within its shell (22) signal distribution circuitry (64), signal combining circuitry (68), and any other circuit components necessary for antenna system (20) to communicate with other stations or devices. Antenna system (20) has radiating conductors (24, 32) tuned to two different frequencies such that simultaneous transmission and reception of signals is possible in the same and opposite directions.

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.
