supporting camouflage netting ?)
The camouflage netting poles are really lightweight and not very
strong. A better choice would be the GRA-4 poles used for putting up
wire antennas in the military. These are also in 4 foot sections, but
are designed to be tilted up up to a 45' height with two sets of guys.
If you find these, the ones with a square shoulder at the joint work
better than the ones with a rounded shoulder. The rounded shoulder ones
can be a bear to get apart. The square shoulder ones also rotate nicely
for armstong rotor work.
