If you cannot attach the radiosonde with the unwinder to the balloon
as instructed – for instance when using a radar reflector – attach the
unwinder with string to a distance of about 10 cm from the reflector
and the reflector to a distance of approximately 50 cm from the
balloon, see Figure 3 on page 12 for further information.
NOTE
The RS92 Digital Radiosonde can be disturbed by strong high-
frequency transmitters of various kinds, such as aerial surveillance
radars and mobile phones. For example, mobile phones should not be
taken closer than 10 meters to the radiosonde.
NOTE
The RS92 Digital Radiosonde should not be closer than at a distance
of 3 m to another radiosonde. This requirement should be kept in
mind especially when performing dual soundings.
