Mike, here is a link to a good filter design program that is free: http://www.aade.com/filter32/download.htm This will let you explore some filters. I use this program at work and it saves lots of ti
When elevated radials are mentioned they are often full 90-degree radials. The low impedance presented by the radials makes decoupling the coaxial cable shield easy. The counterpoise current will div
Sinisa, I should have included some numbers to show the magnitude of the effectiveness of tuned shortened top band radials. To answer the point of Tom W8JI, for a 40 meter ground plane up 20' and hav
Thanks to all for your comments. Tuned or Untuned Radials - that is the question I think the point of my previous post has been missed. The subject is tuned elevated topband radials. I'm wondering ho
Bjorn, is the RF current probe opening large enough to clamp around the coaxial cable? If it is then you are ready to measure. If the RF current probe opening is too small you can use a large ferrite
Mike, Tom's, W8JI, experience with this shows that in hIs situation it is not difficult to deal with. Food for thought for those who have had issues or want to know the magnitude of the coupling.Ther
A couple of questions for the Beverage folks. Are the high angle lobes a problem? Has anyone tried stagered Beverages to suppress the high angle lobes? Dave WX7G _____________________________________
Thie Beverage discussion is quite illuminating. It seems then that the Beverage works well over a wide range of ground types but does not work (as a Beverage) over very good ground or very poor groun
