[TowerTalk] Tic ring feeline

[David Robbins K1TTT]

That may work, you just have to be sure that the coax can't sag down to get
caught in the ring movement bearings or drive.  Since you don't need a boom
strut for support maybe just make a 3' or so vertical support  from the
cradle and do the loop between it and the tower.  It wouldn't have to be as
strong as a boom support strut so you could probably get a local shop to
weld you up some angle iron that you could bolt on somewhere.
