A gas-propelled line deployment device is operable for orthogonally deplog 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.

1. Field of the Invention
The instant invention relates to means for deploying an antenna line or wire over the ground, and more particularly to an orthogonal antenna line deployment device.
2. Description of the Prior Art
A more complete understanding of the invention and many of the attendant advantages thereto will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:
FIG. 1 is perspective view of the orthogonal line deployment device of the instant invention;
FIG. 2 is a similar view with the wire-carrying projectiles and recoil piston exiting their respective tubes;
Referring now to the drawing figures, the orthogonal line deployment device of the instant invention is illustrated and generally indicated at 10 in FIGS. 1, 2 and 8. As will hereinafter be more fully described, the instant invention is operable for orthogonally deploying two antenna lines to a distance of more than 100 feet.
The device 10 comprises first, second and third closed ended tubes generally indicated at 12, 14 and 16, first and second wire-carrying projectiles generally indicated at 18 and 20, a recoil piston generally indicated at 22, a vertical mast generally indicated at 24 for supporting the device 10 above a supporting surface, first and second continuous lengths of antenna line 26 and 28, and a pressurized gas cartridge generally indicated at 30.
The first and second tubes 12 and 14 (FIGS. 1-4) each comprise a generally rectangular body portion 32 having a cylindrical bore generally indicated at 34 formed therein having a closed end 36 and an open end 38. The body portion 32 of each tube 12 and 14 further includes a rectangular opening 40 adjacent the open end 38 of the bore 34, a gas vent 42 which extends into the bore 34, and a threaded mounting bore 44 adjacent the closed end 36 of the bore 34. The body portion 32 still further includes a generally rectangular appendage 46 having a mounting hole 48 formed therein. The rectangular opening 40 is operative for mounting retaining means for retaining the projectiles 18 and 20 within the tubes 12 and 14. The gas vent 42 is operable for introducing a flow of pressurized gas into the bore 34.
