Yes, Tom Schiller, N6BT, founder of Force 12, ran DX using a light bulb followed by a common mode choke so he wasn't cheating using the feed line as the antenna. I believe he later ran a phased array

Thanks... I knew I read about that someplace. changing the length of feed line, in my opinion, has always been an issue. You can't make it shorter, it still has to go from point a to point b and usin

Bottom line: DX performance seems more attributable to the Propagation gods rather than what flavor of wire antenna is being used. ____________________________________ Funny you should mention this.

Mike, the tuner was not designed for 400 Ohms and you won't see any noticeable difference. Once you get to the shack with your openwire, you need to run it through some sort of a balun to the tuner,

Mike, hang on a bit. It's not as bad a picture as you are painting. If you have problems and want to solve them by longer feedline, then you typically need just 1/8 wavelength on the band in question

All good stuff, Stuart. I'm a great fan of the vertical dipole and you prune it exactly as you suggested. I think this is one of our hobby's best kept secrets. The OCFD is a highly misunderstood ante

Because it is 4:1. You are better off with a 1:1 balun. For a better understanding of this, see Steve's page on Tuner Balun: 4:1or 1:1? Here: http://www.karinya.net/g3txq/tuner_balun/ 73 Rick, DJ0IP
