THHN Wire -vs- PVC Coated, UV-Resistant Wire by True Ladderline
I always see suggestions that people simply go to their local big box store and purchase the standard THHN wire for use with antenna builds. I've attached a few photos that show the difference between that wire and the PVC-Coated, UV Resistant wire that we use for our doublets.
The THHN wire that is shown, is less that one year old in the Florida sun. The coating always peels away. It's going to do that.
The other wire I show, is over three years old in the same location in Florida.
I would much rather use the PVC wire. I do sell it by the foot if you'd like some.
As a side note, the same antenna I used in Vermont was up for fifteen years. I brought that same antenna to Florida and the wire still looks like new!
