Hello Paul, How about trying Guy Olinger's elevated FCP (folded counterpoise) and compare that to your radials on the earth? If you're not familiar with it, then just search the Topband archives for *FCP*.
Somewhere in those archives, K3LR mentioned lengthening the inverted-L. So that's what I did. Doing so significantly raises the low feedpoint impedance that a λ/4 inverted-L has (about 17 ohms), and also elevates the point of maximum current. I played with the length in EZNEC and settled on 155' total length. My inverted-L is described at www.w0btu.com/160_meters.html. Lots of other useful information there that you might find useful, also. It has been long established there is little difference in DX performance between the inverted-L and the T-antenna. The small amount of horizontally-polarized radiation from the horizontal (or sloped) part can be very useful. Take some to search the Topband archives, and you'll see why we say that. :-) 73, Mike www.w0btu.com On Fri, Sep 21, 2018, 3:07 PM Paul Mclaren <paul....@gmail.com> wrote: > Looking for the advice of the experienced hams for what if anything I > should do to make my 160m inverted L more efficient.
