HF-Ground

Laying the insulated wires on the ground resulted in a reduction of VF of about 50%. The marked increase in feedpoint impedance was due to the attenuation of the reflected waves arriving back at the feedpoint and agrees closely with my calculations of such. I forgot to say: Note that the dipole laying on the ground was close to one wavelength, yet the feedpoint impedance is not all that high. It would appear that 1/2 wavelength buried radials do NOT present a high impedance. -- 73, Cecil http://www.qsl.net/w5dxp |
