 ```How the antenna interacts with the earth in the far field is a BIG part of it. Try modeling a vertical 40M dipole and a horizontal 40M dipole at various heights, then plot their patterns on the same axes. (that is, save the plots for each, then import one plot into the other's screen display). The horizontal dipole has a greatly superior pattern. A vertical monopole (quarter wave, 5/8 wave, etc.) and variations thereof interacts with the earth in the far field in a FAR better way. I believe it relates to where the center of radiation is. For the monopole, it tends to be quite close to the earth. 73, Jim K9YC _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk ```
