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.
