[TowerTalk] metal guys - antennas - rotary tower

[Art K6XT]

I've been told its necessary to break guys into 9 ft lengths where an 
antenna rotating under the guy will come close, defined as one or two 
feet, from a 25 ft section of guy wire.

What if an antenna rotating under a 25 ft section of guy will come no 
closer than 12 to 15 ft? Still necessary to break up the guy into 9 ft 
sections? Does anyone have any direct experience with this configuration?

Thanks 73
