What is the advantage of this wire over THHN? Flex-weave has hundreds of copper strands, each strand is very small diameter. John KK9A Here in Florida where high winds are fairly common, I use the Da

THHN is in no way meant for use as exterior antenna wire. The nylon (N) coating is thin and stiff. Sent from my Boost Samsung Galaxy SŪ4 What is the advantage of this wire over THHN? Flex-weave has
Correct... THHN is not intended for use as exterior antenna wire, but it surely does work well... I can get it in any color I want and in a 2500+ foot spool, et al. I can replace a LOT of 80m loops f
The problem with using ordinary copper wire for antennas where the wire is under tension is that it stretches. Mine high dipoles are under about 100# of tension (up 140 ft, fed with RG11), so every f
Yes, and after a year or two in the sun the nylon rots and flakes off and changes the RF length a bit with less insulation thickness. For me the DavisRF polyethylene insulated copperweld stranded ste
Roger that, Jim. Until I can get my ENTIRE loop path clear of vegetation, I will have to accept the trade-off and continue to use the insulated stuff. (Maybe this winter, fingers crossed). Since I ca
I use water jugs (don't remember capacity, only weight) filled with dry sand. They weigh 95 -100#, which is my estimate of the tension on a centerfed horizontal wire. I use CMI rescue pulleys and mos
Forgot the link to the pulleys. RP115 is what I use. https://www.cmi-gear.com/ The link below has the lowest price I've seen. https://www.stagespot.com/cmi-2-in-service-line-pulleys.html?gclid=Cj0KCQ
My question was what is the advantage of Flexweave over THHN. Both are 100% copper, Flexweave has significantly more strands which makes it more flexible but how much flexibility do you need. Is ther
Just this past weekend I stripped my low band tower (160 & 80) of all wire and coax (it was an all day job, wore me out!), in preparation of changing the basic design. As far as antenna wire I had a
re #3 I use a pull down line of parachute cord tied to the hoist line on the pull side of the insulator so when something breaks - wire, coax, or insulators I can retrieve the hoist line top end. Or,
Steve and group I've used Toilet Bowl cleaner with stranded wire. It worked. 73 Larry K1ZW Oxidized stranded is more of a problem to clean and re-use if you want to solder it. I suppose an acid bath
Common household vinegar will do it also. You must soak the end to be cleaned overnight. K4TO _______________________________________________ _______________________________________________ TowerTalk

Coca-Cola has carbonated water which is AKA carbonic acid. I'd drink the Coke and use the vinegar on the wire. Patrick NJ5G WA9YBW -- Original Message -- From: "Dave Sublette" <k4to@arrl.net>
