In respect of strength, photostability, price, and longevity you’d be hard pressed to beat it. Imagine a trampoline flapping in the breeze while a dog house flies by. I believe it has been holding on for dear life at least 5 or 6 years now. A single piece of 550 cord about 12 feet long has kept my friend’s trampoline from blowing away more times than I care to count. They even make reflective 550 cord and in any color you might want.Įast Tennessee has some wild weather. 550 cord can be purchased for less than $15 per 100 feet.

It is curiously strong and will out last most things already mentioned. Last option that I haven’t seen mentioned yet would be parachute cord aka 550 cord. Zip ties are cheap and work well if you don’t mind doing some maintenance every so often. Seconded that cheap electrical tape eventually sticks to everything it isn’t supposed to and nothing it is supposed to. Considering that copper is a naturally occurring element it isn’t going anywhere anytime soon unless there is a risk of having a constant mist of concentrated ammonia hitting it. I’ll agree with Rescue161 about solid copper wire out lasting feed line. I had to eventually replace all the runs with new coax. The precise spacing insured the problem would repeat at the exact same frequency and compound the problem over and over. Problem is they squished the coax and the VSWR went through the roof. I had a vendor install some long runs of RG-11 off some satellite dishes and they did the most beautiful job with stainless ties placing them the exact same distance apart to probably within a mm. Stainless ties from Panduit and others are fine but you have to be very careful not to squeeze or distort the coax.

If you want the best of both worlds use a Ty-Rap first then cover it with Scotch 33+ to keep the UV from destroying the Ty-Rap over time. Scotch 33+ has actually outlasted black Ty-Raps at the same location. When you do that the end gets shriveled up and doesn't stick well, eventually starting the unravel process. The trick is to cut the end and stick it down and not stretch and pull it apart to cut. Scotch 33+ electrical tape has lasted over 20yrs here holding coax and cables to masts and things outdoors.
