[Antennas] which way the wind blows

[Bill Marx]

I have a KT34XA and after suffering through many Hurricanes in South Florida
I always put the elements into the wind. The antenna seems to show less
stress in that position. The back and forth motion against the rotor is less
in that position as well.
