I recently got a picture from a ham in AZ who had one folded kind of like a
3/4 of a rectangle. He is in the lowband antenna business. Looked like a big
magnetic loop up over and back down on a van. Radiation resistance
measurements made his point. Looked like a cloud burner for 75.

Those tubes are "out in the open too" IE, no covers<:-)) I use the same
set up in my shop where I have 22 8' tubes mounted in 2 tube fixtures.
Forgot and left them on last night. My wife (N8JBW) says it's coming out
of my allowance. <:-))
