[SFDXA] Mast pipe load calculator on DX Engineering Site

[WILLIAM MARX]

Hello John,


The DX Engineering Mast Load Estimator was my idea. It certainly takes the
guess work out of designing antenna loads on a mast. It is easy to use and
it's free.

Thousands of evaluations have already been run and it's only been on the
website for a month!

The calculations and results have been fully vetted through many amateur
radio antenna installers and also through professional mechanical engineers.
The results are accurate for the variables that are part of the evaluation.
We beta tested the estimator with a focus group and many of their
suggestions were incorporated.

No safety factor is applied to the estimator result. This was done on
purpose so people would not overload the mast with antenna wind loads and
then count on a safety factor to cover the overload. And yes, it only works
accurately for the DX Engineering masts that are in stock.

I hope this answers your questions.

73!

I am not sure what the safety factor is of the program. It is a nice tool
if you are using their 4130 masts.  There is no option to change the
material or wall thickness if using your own tubing.

Your proposed layout seemed reasonable, can the rest of your system
withstand 100 MPH winds?

I found a really good mast pipe load calculator on the DX Engineering web
site.
