Dave, Too late, I have just refinanced my house, but how about forwarding the other offers ? Merry Christmas to y'all (as we say in Virginia) de André N4ICK
Hi Rik, If one uses the four probe method of measuring ground resistivity, the problem of contact resistance with the ground is overcome. Current is injected into the soil through the outer two elect
Ralph You'd have to use an isolating transformer here because one side of our mains is earthed. Sounds exciting though, I remember testing my earth system when I was a lad, by connecting the live sid
Has anyone measured earth resistance alone under different conditions? If I recall correctly, this can be done with three earth stakes and Kirchoff's laws. Mike, G3XDV I am wondering about that for
Sorry about that. Here is the test of my message: Ralph "Ground Conductivity Test" is from the ARRL Antenna Handbook... The book I have is from 1994....and it is on page 27-35 that's chapter 27 page
Here is the method used to measure ground conductivity as suggested by ARRL. In our case, use RF rather than 60 hz. Ralph -- Original Message -- From: [email protected] Dick Rollema To: rsgb_lf_
