Abstract : A gas-propelled line deployment device is operable for orthogonally deploying two antenna lines to a distance of greater than one hundred feet. The device includes first, second and third tubes, closed at one end and open at one end, the first and second tubes being arranged perpendicular to each other and the third tube being arranged along the resulting vector of the axes of the perpendicular tubes. The first and second tubes have wire-carrying projectiles received therein and the third tube has a recoil piston received therein, said projectiles and piston making a gas tight seal with their respective tube. The recoil piston has a larger cross-sectional area than each of the first and second wire-carrying projectiles. The device further includes a retainer mechanism which is operable for retaining the wire-carrying projectiles and the recoil piston within their respective tubes until a predetermined gas pressure is achieved. The retainer mechanism is further operable for automatically, and simultaneously releasing the wire-carrying projectiles and the recoil piston when the predetermined gas pressure is achieved within the closed ended tubes. When the wire-carrying projectiles are launched, the recoil piston produces an equal and opposite reaction force to the wire-carrying projectiles so that the device is essentially recoilless.
