ON4UN?s book, 3rd edition, Chapter 9, page 9-46. Pretty simple concept?the vertical portion is ¼ wavelength, and the total horizontal length is ½wavelength. Higher radiation resistance, not nearly as
Hello Mark, As soon as you add a few 120 ft radials on the ground, this antenna will starting working better. The more you add (to a point) will even help more. Don't worry if they can't be all the s
Thanks very much to so many fellow hams who responded to my original post! Nice to know the fraternity continues to help those with questions. This afternoon, a lovely fall day in North Carolina, I a

Hi Mark, N6LF recently found that the optimum radial length depends on how many radials you lay down. Check this out: http://www.w0btu.com/files/antenna/Optimum_no_of_radials_vs_radial_length.html 73
doing my best to improve my 160 capabilities on a small suburban lot. Only have G5RV up at this point, flat-topped, at about 30' Runs mostly N-S. I have added connectors to allow me to make it a "T"

I should have included this link: http://www.antennasbyn6lf.com GREAT information there. 73, Mike Waters www.w0btu.com ________________________________ ... Hi Mark, __________________________________
Two long radials on the ground is only one step above using just an iron pipe in the ground. That should be common wisdom, like high dipoles do better than very low dipoles, but alas, is not. Try two

Mark my tee vertical design via the web page http://www.wcflunatall.com/nz4o9.htm was for a "voltage" fed electrical half wave tee tuned with a parallel network, not a 1/4 wave current fed tee tuned
