YES!! firsthand...
W7HPW's original four square of 3" (or was it 4"? can't remember) irrigation
pipe came down about six months after it went up. All four of them. They got
some kind of a resonsance/vibration going during a storm and it fractured the
tubing part way up. I think they were guyed at two levels. I know people use
this stuff to do four squares; I know it's cheap, light, and easy to work with.
Some may have better luck than others. But is it certainly the wrong material
to use for something like this.
He replaced them with some verticals that Zero-Five put together, very well
made, thick wall tubing at the base with a nice taper to the top.
If I had the land to do a foursquare, I'd use F12 Sigma vertical dipoles. No
ground wires to lay down!
