Re: [TowerTalk] 2 inch Chrome Moly mast needed

For years I used the online WD9P calculator but it has disappeared. When
VE7RF mentioned the ARRL calculator today I did a quick search and found
this post

##ARRL has a free, dead on accurate  mast calculator.   You can plug in any
OD,
any wall thickness, and any yield strength .  Then insert the yagis at any 
point above the
top of the tower, windload on each..and it spits out the survival speed in
mph.

I have seen reference to this calculator many times but I haven't been able
to find it. Where is it? Buried somewhere in all the stuff that comes on the
Antenna Book disk? I hate to install all that to get a mast calculator.
