Hi Mike,

I always attach the cables to the standoff arms, and when the tower's all
the way down nothing hits the ground (since in my case, the cables run
across the roof to the shack).  This isn't for "looks," it's to keep the
cables off the ground, where they would be most easily damaged.  This also
helps to assure that no cables can end up going through the lower tower
webbing where they can be sliced in half as the tower comes down (!) and
other evils.  (With a manual crank, cables can end up twisted around the
crank handle -- I've seen everything.)

To protect the cables where they run through the standoff arms I usually use
a large diameter water hose, run the cables through the hose, and tape the
hose (not the cables themselves) to the standoff arm.  In some cases, the
standoff arm cable support "Y" or "U" must be bent open a bit wider than the
factory setting in order to make room for the hose/cable bundle.

Sometimes I pack something like foam rubber material into the hose as well,
to take up any space left.

Seems to work for years and years without any problems.
