So I hung a homebrew W3EDP antenna over the last weekend. It actually seems to be performing pretty well. The specs call for 450 ohm window line, but I used 300 ohm twin lead instead, as that's what I had on hand. I'm using an LDG 4:1 balun at the feed point. The internal tuner in my IC-746 is able to find a match on everything except 160m. I have an "ugly" balun/choke at the feed point, which seems to do a pretty good job of keeping RF off the feedline and out of the shack. The specs I've seen recommend a current balun on the feed point. The LDG is a voltage balun. So my question is can expect any performance improvement by switching out the voltage balun for a current balun?
