[TowerTalk] Rotor Loop at the Top of a Crankup?

[GARY HUBER]

On a Rohn 45-G flat top I used six feet of Non-Metallic Conduit which had an 
internal diameter large enough to pass a PL-259 and ten feet of RG-213/U. 
The guys on the tower dressed the cable down the mast,  wrapped the cable 
and NMC assembly around the mast one and a half times then tied the low end 
of the NMC to one guying hole in the top plate.

All-

I am building a SteppIR DB42 on a TiltPlate on the ground, at the top of my
cranked down and tilted-over HDX-589.

I now need to decide how to route the cables.  The bottom of the TiltPlate,
which has some sharp edges, is about 2 feet above the tower top.  I'm
thinking of leaving two or three 18" diameter coils of the coax and SteppIR
control cable wrapped around the mast, between the bottom of the TiltPlate
and the top of the tower as the rotor loop.  But I am concerned the cables
will drag along the three top corners of the flat tower top and be abraded
or even snag something.  I could put the cables inside a piece of garden
hose to protect them, but that wouldn't avoid the snagging problem.  It
almost seems like I need a flat disc just above the tower top for the loops
to lay on..?

Do you have any suggestions on how to dress the rotor loop to avoid having
it abrade on or snag the top of the tower?
