Forget the sloppy sloper...
You have a nice support... What I suggest for a temporary antenna is a bent 
dipole, fed with coax... Use a 2x4 clamped to the tower to hold the upper end 
of the antenna 5 feet out from the tower... Slope the upper half of the dipole 
down to a support/tree, 8-10 feet high and roughly 100 feet out from the base 
of the tower... Your coax feed point will be within a few feet of this, one way 
or the other...  Continue running the remainder of the dipole straight away 
from the tower on the same compass line as the sloping half, maintaining the 
height off the ground...

Trim it to resonance at the lower end - not worth the effort to keep climbing 
the tower...  It will play nicely...
