Remember that the Tower is only as strong as its weakest
link. I have seen some guyed with only one cable clamp on
each end. The Worst example 110' Tribander - 2 el 40 mtr
Stacked. Good Coax ,.etc. Used one cable clamp on this
Plastic Covered Clothes line Wire.. Was in a Hurry to get
on the air And did not wait until he could get proper Guy
wire.
It Did Not Last A Week. Tower is only as strong as the
weakest link. Better to save money on the Rig than on the
Tower. And Don't get in a hurry.
