I have a similar situation and solution that has worked similarly.
RG-218 (like LMR900) and rotor cable, SteppIR cable, misc coaxes
all taped together.  Very stiff.  Forms very large loops on the
ground.  At the top I have a pipe with Kellems grips to hold
the coax, so the coax arm at the top is not supporting the weight.
 From the top of the RG-218, there is a short run of Buryflex
wrapped around the mast up to the antenna.

On the coax arms, I bent the loops open so they have the shape
of a "U".  I then completed the circle by slipping the correct
size rubber hose over the ends of the "U".  The rubber hose was
stuff I got at the auto store for gasoline.  Now I have a very
roomy loop to let the cables dangle in.  This is on a 106 ft crankup.
