Dacron antenna rope is strong, top-of-the-line double braided rope and has the qualities of high strength, limited stretch under load, UV and abrasion resistance, and low coefficient of friction as opposed to other rope types such as nylon, polypropylene, hemp or cotton, all of which do not have these qualities.
It won’t break down – it is black UV-resistant – and won’t stretch under adverse conditions or strong sunlight. This rope is great for use with aerial antennas, verticals, gin poles, and telescoping masts.
