Hi Gang, I am planning to try this antenna for the winter and need more information. The author, NE0U, seems to have no known email address that I can find so here goes. 1. I assume that the vertical
If the feedpoint is elevated you should have 4 tuned radials. If it is ground mounted it needs radial field just like a vertical. 32 is a decent number more is better of course. They don't have to be
Installing a dense radial field in the first 50' is the most important step for a small lot. Galvanized and plastic dipped rabbit fence works wonders for that. Solder wires to the ends to extend the
How high off the ground does the feed point need to be on 160 to be considered elevated enough to use tuned radials? I have the space - nine acres - but deer are an issue with radials. Mike, k5wmg st
I run mine at 12' so I can get a truck up the path to the back acreage. Carl KM1H How high off the ground does the feed point need to be on 160 to be considered elevated enough to use tuned radials?
High enough so people can't touch it would be my answer. Mike W0MU J6M CQ WW DX CW Contest 2011 J6/W0MU November 21 - December 1 2011 W0MU-1 CC Cluster w0mu.net ______________________________________
May elevated radials be horizontal? May they slope upward? Or must they slope downward? If so, how much of a slope is needed? Jerry K3BZ High enough so people can't touch it would be my answer. Mike
The antenna efficiency will improve as you add more elevated radials beyond just 4. Eight to fifteen feet of feedpoint elevation isn't sufficient to reach theoretical efficiency with just 4 elevated
One QST article from back in the 80's suggested sloping up from about 8-10', which was a comfortable place to work at, then a 45* angle to 20' and then horizontal. Perhaps someone has the details han
