And K7NV would be disappointed if I didn't also caution to be careful that
the antenna wind area figures you use are calculated on the same basis as
the numbers that Trylon uses to rate its towers. Combining apples and
oranges can result in trying to put as much as 1.5 times the rated amount
of antenna area on the tower.
