I have a 1970's vintage LM470 which has separate pull-up and pull-down
cables for the sections....maybe not 8 for all 4 sections, but certainly
more than one long cable.
Years ago I got replacement cables from Tri-Ex and some of the cable lengths
were a few feet too short or too long (I forget), but Tri-Ex made good on
the corrections. Point being there are some subtle differences in various
models over the years. But they are all basically the same.
I have never heard of a single cable for the entire tower, especially that
the design uses separate pull-up & pull-down, but perhaps earlier versions
did? I can say for sure my 1970's "D" version used independent cables.
The model plate is hidden out of view (and is often painted over) below the
cable drum, but you might get lucky and find a model number.
Download the manual from BAMA, it shows how the wire rope is laced. Might be
too new a manual for your model tower, but at least a start.

Subject: [TowerTalk] Triex LM470 Recabling question
I've ordered and received the replacement cable from Tashjian the cables for
my lm470. Only problem is my lm470 cable was one long piece whereas the
ones Tashjian sent are multiple pieces for each section. My question to
those who have worked on these towers is will the multiple cables work with
the older 470? I'm not sure where one would tie off each cable to the
previous section. My cable was one long cable all interacting with each
section simultaniously. Tashjian says it will work but how or where do the
cables get tied off then? Is there an advantage to using multiple cables as
opposed to one long cable? I understand the newer cables means the tower
won't nest down quite as far but other than that what are the differences or
advantages to using multiple cables if any?
Thanks
