Lonnie,
I bought this on the Internet:
It works good & I get a lot of looks & questions. It's 16 feet high from the holder on the ladder. We have had 35 MPH winds with No problems. It collapses to 4 feet for storage & it's made of Fiberglas.
This is the web site:

Hope this helps.....let me know if I can answer anymore questions for you.

Just an update......I installed the mount just below the top step for support. Don't install the way they show it on the web site. The wind will bend the ladder slightly as they show in their pictures.
