Abstract
A reusable portable device for providing location data by a lost individual as well as a signal enhancer for radios or other signal emitting devices. The device is in the form of a briefcase size unit containing a deflated airfoil with air brake and a gas cylinder containing ligher-than-air gas such as helium. The helium is released into the airfoil and is temporarily sealed with a clip. A signal emitting tether line attaches to the airfoil at one end and a reel at the other end. The reel contains a trim capacitor to adjust frequency of the antenna to different signal emitting devices which may be attached to the reel. Incorporated into the reel is a lightning arrestor which can be attached to an anchor permitting use in adverse weather. The reel may adjust the height of the airfoil and bring it back to the ground to be deflated and reused another time.
