Of course it does not calculate your structure's limitations or the antenna
survivability. It is a nice tool for free, but it only works with their 2"
and 3" 4130 masts. If you have a different diameter, different wall
thickness or use 1026 steel or 6061 aluminum this will not work.

TT:
I just tried the tool with my antennas. Be carefull! Apparently the calcs
don't tell you anything about your tower's limitations. The calcs merely say
that the DXE MAST will or will not fail at the given wind speeds; they tell
you nothing about the survivability of the tower. In other words, a big load
may survive on a 3 inch DXE mast, but it might bring down a stack of Rohn 25
or a light-duty self-supporter.
Caveat Amateur!

DX Engineering just put a nice little utility on their website to calculate
loads on a tower mast. It's pretty handy when trying to figure out what
antennas a mast pipe can handle.
