Oooh Kay. The US military GRA-4 antenna [5' Al poles that you could push up by adding sections at the bottom, had nylon guy ropes and nylon haul ropes for the [usually] fan dipole. My team and I used these in Vietnam and Laos for 4 years. Nothing ever broke or fell down, and I still have about 150 International Feet of that now 45 yr old rope under the back seat of my truck ... not sure why, but it seemed like a good idea at the time. Even if you weren't there, you can probably imagine the tropical sun, rain, and resultant mold. This rope survived far better than my feet did. I have two wires suspended between my tower and trees on nylon rope. It's been a long winter, however it does look like it's ending and we'll be in "forever clear and sunny" weather in triple digits soon [we hope :-) The rope shows no deterioration, been up for at least 4 years now.
