Dual braid, poly rope works well and I think you will find the 3/16ths will be sufficient at two levels on the 54' mast. Either should work. I use a Lexan disk, or ring cut with two hole saws. (Do th

Doug, I use 3/16" Dacron covered rope to support my 70ft vertical. It is made of 3" and 4" irrigation pipe. 1/8" Dacron may work for your antenna. Mine has held up for more that 15 years. Dacron is U

Dacron has very low stretch and is available in black which is pretty UV resistant. Nylon is pretty much like guying with rubber bands. Patrick NJ5G I am working in a vertical for low bands (160, 80
What about Kevlar rope like one used in spiderbeams? They also claim it is UV resistant and does not stretch. _______________________________________________ _________________________________________
I've used the small Kevlar (about an 1/8" in diameter) cord for boom and element trusses and it works great. But maybe not so great for supporting the ends of inverted vees. The last 80-m inverted ve

Unprotected Kevlar is susceptible to the elements. It's normally sheathed in PVC The ends are capped and sealed to keep moisture out as in Phillystran. It's a bit on the expensive side, but I use it
I am trying to get the "550 Paracord"...it is not available here but will see what i can do to get it... I read/hear many people used in verticals and it is strong and UV resistant and very cheap com
The biggest issue with paracord, which I would not expect to be available in Cuba as it is a U.S. Army spec, is that it is what is called a dynamic line. It stretches when put under load. It is used

Quite strong UV resistant cordage is typically used to make/mend nets such as for purse seining etc. Black Dacron is popular for this and makes good guys within its strength limits. Patrick NJ5G On 8

In other words, "double-braided Nylon" rope.The Nylon material does well with UV.The double-braided construction is bestto limit stretch. It is used a lot on sailboats.You'll find it in a marine supp

Nylon is used on boats because it stretches like a rubber band and when used for an anchor line does not transmit much shock to the deck hardware. For hoisting sails (halyards) and for sheets (lines

I use DOUBLE-BRAIDED Nylon rope because, as I said, it stretches a lot less.Other materials constructed the same would behave similarly (the material is only ONE factor. The most "stretchy" construct
