keeping wire antennas up

A problem seeking a solution.
I live in a wooded area of the Pacific Northwest with dozens of fir
trees of
100 ft or more in height that make wonderful supports for high dipoles
and
other wire antennas. These particular trees have very few limbs at
anything
below the 60 ft level so using a crossbow or slingshot for installation
is
not practical. I have been forced to employ a professional tree
climber to
install the eyebolts and halyards. Using this system, the antennas can
be
raised and lowered for maintenance or modification.
This system works fine until our winter storms kick in. Often, during
those
storms, a tree will lose a limb or two and take the antenna down with
it. I
am then left with a halyard tied to an insulator 50 ft or more above
the
ground with no way to get the insulator back down short of hiring
another
costly climber.
Does anyone have any solutions to this problem?
Install continuous loops through all your pulleys rather than
"halyards". Hauling one side of the loop hoists the insulator and
hauling the other side of the loop brings it back down to where you
can work on it. Regardless of the condition or fates of wires
suspended between pulleys.
