Hi all,
I'm about to install the first of 5 rotary towers here @ 9A1TT. This is the
smallest at 31m but they all based on triangular 6m segments measuring 50 or
60cm to a side.
Concrete will be poured for the base and guy points on Monday...so I'm quite
excited, having waited 4 years for the paperwork to be cleared :)!
Now to my question.
The tower sits on a typical base (with 3 phase motor) that measures 1m in
height. The system looks very similar to those on offer at XG and RTS.
What I haven't seen anywhere (at least not documented online) is a mechanically
sound yet elegant solution to handle the coiling of coax and control cables as
the tower rotates through its 450o.
The tower will carry 4 mono-banders, an electronic compass for rotation
controller and a safety light on top...perhaps later another yagi for 6m..or
alike.
I'm opting for 10-15mm flexible coax to run the length of the tower and into
the concrete.
So I have a "cable loom" (or 2, if I separate coax from cables) which is no
larger than 50mm outer diameter.
I considered using a cable drag chain to support the spiral and protect the
coax etc... but haven't ever seen one used for this application.
Or am I complicating matters (wanting the loom to look as sexy as the tower
:))...and will a flexible UV-resistant conduit suffice?
What do you use? Pictures to my email much appreciated :).
