[TowerTalk] Adding Expanding Foam inside boom

[john at kk9a.com]

I'm not sure how you would completely fill a 12' piece of tubing with the
foam and I think it would have the potential to trap water.  I like to
keep my booms completely open (no end caps).

Has anyone tried this ?
Can it improve survivability of very large yagis?
It won’t prevent a boom failure, but could it help last a little longer?
