All:
I've had cases with my homemade full-sized 3L 40 (which has severe
element taper and small diameter tips) where ice loaded the elements to
the point where the tips were pointing straight down. Jerking the beam
back and forth with the rotator caused the elements to flop around
enough that all the ice was shed and the elements sprung back to normal.
Really.
Still, these conditions were not as severe as those endured by our W1
brethren his past weekend. My empathy goes out to those who lost
antennas. As K3LR says, our hearts break to see the results of your
hard work damaged.
73,
