to thine own sound be true


Where can I buy one of those? I started using 2.5" poles from a local
pipe shop, and I have one mast that is 21', and another that is 8 feet
with three feet down in the concrete. The problem is, I can't even add
10 feet to the mast because the joining point seemed too flexible when I
was trying to insert it ...

This 50' $70 solution sounds like the ticket to me.
