I have tried to sketch out the cable stringing of the tower using a large
bag of clothespins to snap onto what I have already sketched but am not
confident of being accurate. I would certainly try to follow the advice of
pulling the new cable through by attaching to the old cable(s). If anyone
has a sketch I would appreciate receiving a copy.
But before going to all that trouble and expense I would carefully inspect
the cables and if showing no nicks, corrosion, or rust would leave them as
is and instead replace the momentary down-off-up switch with a non-momentary
one. That would allow one to throw the switch to the desired direction,
stand away from under the antennas, and apply power while watching from a
safe position.
