A good RF ground

Hi Richard, Not particularly. Also, is there anything I could place around the cylinder to better the conduction between the cyinder and the earth around it? You could slit the cylinder lengthwise and lay it on or beneath the soil. Should I drill holes in the cylinder so I can pour water into the cylinder to keep the ground around it moist? This a bromide from the late 20s and 30s. Yes, it would keep the ground moist, encourage moss, and increase the density of earthworms. Would I still benefit from some radials in the ground? Always, first, and foremost. My garden's about 33 foot long, 21 foot wide. Ground gets rather rocky and a bit sandyish at about 9 inches or so from the surface.TIA. Lay out a fan of radials as far as you can go. Make it about a dozen to sixteen. Move on because there is small chance of significant improvement beyond that. 73's Richard Clark, KB7QHC |

The casing of an abandoned well gives me about a 4 ohm 60 hz ground but about 25 ohms ground on 20 meters. Jimmie |
