STI's Double-braided Polyester Antenna Support Rope was originally developed and manufactured at the constant urging of a local Ham radio operator. His years of expertise in amateur radio equipment, combined with ours in braiding various fiber, inspired the development of this special double-braided rope to fit the needs of amateur radio operators.
STI's Double-braided Polyester ropes are not weakened by decay or mildew and provide excellent resistance to abrasion. The color sealed black polyester yarn used in the braided jacket also protects the cord from ultra-violet light.
The break strength of our antenna support ropes are computed by using the grams per denier information published on the McGraw-Hill Man-Made Textile Fiber Chart. The care and handling and applications have significant effects on the strength of the braid. Therefore, we do not guarantee the exact break strength, but offer the following chart as a guide.
Diamaeter: 2,5 mm
Lenght: 150 m spool
