The wind survival of an unmodified Hy-Gain TH3Mk4 is approx. 96 mph.
Refl 96 mph
DE 102 mph
Dir 108 mph
Boom 123 mph
If 1.125" x 0.058" x 30" doublers (inserts) are added inside each 1.25" x
48" tubing section near the boom, the element survival can be increased to:
Refl 121 mph
DE 132 mph
Dir 141 mph
These are all with "no ice".
