Some very interesting food for thought there, particularly the plots (figure 15, page 13) showing the change in gain for adding radial length. Fractions of a dB (as in <0.1dB) for going from 0.1 to a
One of the least accurate uses of any Gerry Burke (of NEC fame) told me that some people had tried to measure ground characteristics by running transmission lines at low heights above the ground. I d
George Hagn started with measuring the feedpoint impedance of a dipole suspended above the ground, and then trying to invert that to ground (and foliage) effects. He said he eventually went to the Op
Yes, Gerry said the measurements were done with the "Owl Kit" Rick N6RK _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather
looking at the Apparently, the problem layers" is relatively the "run of the mill not. (Having tried agree... ). Small big effect. I've made similar measurements here, but with ladder line inside a
The OWL kit is basically two copper plated rods and some jigs that allow you to insert them into the soil at a precise distance apart. You use a standard impedance bridge to measure the impedance, an
