here some help from my friend google.com
The "father of crank-up towers," Lou Tristao, KG6VY, of Visalia, California,
has died. Tristao, a past ARRL member, was 86. According to Steve Morris,
K7LXC, of Tower Tech, Tristao started Tristao Expanding Masts, which became
Tri-Ex; Tristao Towers, which became US Towers, and the Wilson line of
crank-ups.
