The radio link is resistant against effects of wind with speeds of up to 33 m/s (120 km/h) without
influencetotransmissionquality.Reversiblechanges,i.e.,elasticdeformationoccuruptothewindspeed
of 56m/s (200km/h).Permanent deformation can
occur above this threshold, however, without damage
toODUitself.
The protected terminal box is intended for stationary use in locations protected against climatic
conditions.
