Shunt fed vertical?
Hey John... Glad to see you are still experimenting with the
vertical... One answer is that you are shunt feeding a vertical monopole near it's third harmonic tapped at about 1/8 wave above ground... Depending upon shunt spacing and the diameter ratios it looks like you found the magic spot for that frequency to transform to nearly a 1:1 match... As one fella said to me long ago, I would rather be lucky than good, any day... denny - k8do |

My dumb questions should show that the 28 foot stick still has lots to teach me. I am beginning to get a little impatient to move on to a permanent radial system and a taller antenna. Shunt feeding would simplify lightning protection and physical mounting considerations of a taller stick. John Ferrell W8CCW |
