While the topic is mast material, I have a question. I have a 15 foot piece of 1/4" thick aluminum mast. I am considering using this to come out of 50 feet of Rohn 45. I plan to put the Mosely CA-53 beam on it along with an 11 element 2 meter beam. What is the group's experience/thinking about using aluminum mast? Ken W8ND
