Frank Travanty, W9JCC, has written an Excel spreadsheet and an

>accompanying article which I have used for my TX-472MDP tower. It  
>does just what your looking for in terms of allowing you to graph  
>your particular installation.
>
>It takes a bit of data input in terms of your particular tower. You  
>will need wind loading figures per section, amount of overlap of  
>sections. psi rating of your mast, antenna windloading figures and  
>some other data all of which I don't recall since using the sofware.  
>Anyway, you end up with a nice graph of height versus wind speed  
>maximum for your installation.
>
>I thought it was very well written and implemented. I have a copy of  
>the Word document and the Excel spreadsheet. Contact W9JCC to see  
>about getting them. I'm not sure if it's OK for me to send, but with  
>his permission, I would be glad to forward a copy of each.
