If you have rope at the ends of the wires you can get out your old Scout hand
book and look up how to tie a taut line hitch out at the ends of the rope. Then
as the tower is lowered you, or a couple of assistants, can run up the slack
with the hitches, just like tightening tent ropes.
Sometimes old fashioned simple technology works the best.
Good luck
