[TowerTalk] fiberglass masts

[Jim Hoge]

For get the idea! The masts were  designed to be used with only a couple sections joined together to support a tent or canopy, certainly not robust enough for 40', let alone 70'. They are too loose at the joints and would require too much guying to make them stable if you can even erect them to that height. We tried them at this past field day and quickly resorted to plan B. It was like trying to hold  an overcooked piece of spagetti at the bottom and expect it to stand up. The ham who brought them quickly disposed of them.
