ABSTRACT:
A flexible cord and antenna is paid out at a controlled rate from a radiosonde as it is lifted into the upper atmosphere by a balloon. The cord is knit into a tubular body and folded into a compartment in the radiosonde. The extended end is wrapped around the rotor of a centrifugal brake which limits the pay out rate. The knit tubular body unravels as the cord and antenna are paid out.
