I use three loops, and have the rotator set at the loops “tightest” point (depends on which way you wrap the loops) when installing. The loops change size very little when rotating so no risk of snagging anything. And they are self supporting.

Subject: [TowerTalk] Rotator loop - another question
In my old station, someone came up with this idea - instead of an actual
loop, start with the rotator at mid travel and wrap at least two *loose*
turns of RG-213 around the mast, then connect to the balun or
feedpoint. It worked fine with no problems in 20 years.
It seems to me that doing it this way provides physical support for the
loop, which could be beneficial in high winds, but when I was putting up
my current yagi, people working with me poo-pooed the idea, and so I
wound up with the conventional loop. It hasn't failed yet, but...
So, what's the informed opinion?
