Radar Reflector
Attach the unwinder to the radar reflector with a rubber plate accessory
(Vaisala code RS46158). The rubber plate accessory lets the unwinder
swing properly, making sure that the suspension string is unwound
smoothly.
1. Tie the radar reflector to the balloon with a string of approximately
50 cm in length.
2. Attach the rubber plate (RS46158) to the radar reflector.
See Figure 9 on page 22 for details. For unwinder attaching instructions,
see section Radar Reflector on page 41 .
Non-Totex Parachute
If you are using a parachute that has no firm objects to prevent the
unwinder from twisting, you have to use a hanger board (Vaisala code
RS46157).
1. Tie the parachute to the balloon with a string.
2. Tie the hanger board to the parachute with a string of
approximately 20 cm in length.
See Figure 9 on page 22 for details. For unwinder attaching instructions,
see section Non-Totex Parachute on page 41 .
