Pertaining to a ground-mounted vertical antenna with buried radials a few inches below the surface of the grass: Do ground radials have to be electrically the same length as the main vertical radiato
Scott, There are a lot of myths and a great deal of misinformation out there about radials. That's mostly because good radial systems involve work, and we all hate to work. length as the main No. Rad
Scott, It doesn't matter - ground radials are not resonant. Just put down a bunch of wire and it'll work 73 Ted At 02:30 AM 10/22/2004, Scott Fike wrote: Pertaining to a ground-mounted vertical anten

Yes, and even more when buried. The velocity of propagation is proportional to the square root of the dielectric constant if I remember correctly, and soil is a good dielectric. Think about it this w

At the risk of repeating, don't confuse resonance with the point of peak efficiency. They are entirely different issues. 73, Tom W8JI on the You can do high, find the ________________________________
a few wavelength books can to I think the rule is this: "Use as many radials, up to 1/4 wavelength long, as will fit in the space available, such that the distance between radial tips does not exceed
Buried radials are basically a means to improve the conductivity of the soil under the antenna, not as a resonant part of the antenna (if nothing else, the resonant length in soil would be difficult
