I had a few hours free yesterday afternoon, so I began the dual 80/160 radiator inv. L project.
In the process, I found that water had entered the coaxial center insulator that was used at the feedpoint of the antenna. Does anyone have a favorite solution for a weatherproof, coaxial feedpoint for this type of antenna??? The radials are attached to several load center ground bars, that are screwed into a copper pipe that is driven into the ground. The pipe gives me a rigid mounting point for some kind of insulator or standoff. BTW, after a temporary fix, I ran some quick SWR tests. There appears to be very little interaction between the elements. At least from an SWR perspective. de Art NK8X ᐧ On Mon, Oct 17, 2016 at 11:16 AM, Art Snapper <[email protected]> wrote: > I was considering adding a second vertical element to my 160 inverted L. > This one would be roughly a quarter wave tall for use on 80. > > I tried modelling in Eznec, but wasn't comfortable with the results.
