To the left, I have my trusty 49:1 balun with 64ft of 20AWG single copper strand insulated wire which was mounted for 3 months. I was successful at making several QSO's on it, however, the UV rays quickly took a toll on the insulation (notice how the wire is now pink instead of bright red, and practically white in some places). Next to it is some 22AWG multi-stranded aerospace quality wire which I was using on a similar endfed in my back yard. That particular wire had been outside for almost a year and still looks to be in the same condition it was when I put it up. I have talked to Russia, Central America, Bulgaria, and Europe on the wire in the middle with no problems. Next to it (right) is a random spool of multi-strand 14AWG that I just got off of eBay. I replaced my existing endfed element with it this afternoon in hopes of gaining some extra bandwidth. So far, audio reports have been good and we will see how well it holds up this summer. While I may gain some extra bandwidth using the heaver gauge wire, it is doubtful that I will see any dramatic increase in the number of stations worked because propagation conditions basically "are what they are" at any given time. I have seen that most commercially available endfed and traditional dipole kits use the 14AWG as well, and I am wondering if there is a particular reason for this. Folks, what kind of wire do you normally use, and what have your experiences been?
