Unfortunately, all that winding around the mast is not rotation loop
(it's the way the mast extension is handeld).  The lines (actually
the "nycoil" conduit) are still attached firmly at the top/bottom of
the mast.  There are separate rotation loops for the RF cable going
to the microwave power amplifier (or transmitter) and the radio's
power/control cables.
