Stefan, My main interest is MW-DX, VLF is just a side interest. The beverages will be taken down when the cattle get out and the land is used by farmers around March. Around April/May my interest cha
I installed about 20 earth rods around the periphery, with a couple in the centre region, of a small garden abt 6m x 12m with heavy clay soil. Each rod consisted of as much 15mm copper water pipe a
Hi Jurgen, For cave radio, where we use earth connections, we typically get a few hundred ohms. We are normally in shallow soil over rock, though, so maybe you could do better. The surface area is ce

Hi, When discussing earthing systems using 15mm pipe a friend said that they connected a garden hose to the end of the pipe and ran water through whilst pushing the pipe in. I believe they got furthe
For your information, We use an equqtion for calcurate earth resistance which was proposed by G.F.Tagg (Geoge Frank Tagg) in Switzerland. Some of us have measured it by their own earth resistance met
I once did the same, let water run in the hole while pushing the rod up & down Yesterday I told this to an electrican who built a few grounding systems. He said that this isn't allowed, because alon
Hello Clive, I have pushed a number of 3 meter long 15 mm copper waterpipe in the clay here each within a minute. The trick is to move them up and down whilst pushing in. 73, Roelof, pa0rdt
I just discovered that my ground rod isn't ideal by having the assumed 0 ohm to earth. Measuring with 10VDC the current from neutral/waterpipe to the rod gives about 140 ohms. I use a 8mm rod 1m long
