[600MRG] Ground Rods - Connection To -

[Merv Schweigert]

If you want permanent connections to a ground rod without any clamping etc
I use cad weld products,  it actually welds things together and does not 
require
and special tools or skill.

Other than that my 4 inch copper strap and 480 number 10 ground radials 
are "brazed"
together at any joints using a torch and copper alloy brazing rods.

Ground rods are not RF ground,   they are lightning grounds,   RF does 
not go
8 ft into the soil and return to a ground rod someplace.
Theres a big difference in a RF ground and lightning or electrical 
ground for a
power line etc.

> For the past few days we have seen recommendations to minimize the contact resistance between a ground rod and the earth.  Included were recommendations on minimizing the effects of corrosion.  Maybe I missed it, but I'd like to see recommendations and "how I did it hints" on making a long lasting - low resistance "electrical bond" between the ground rod and the stranded / solid copper wires or woven braid used to join the shack, and if used, the radial field to the ground rod(s).  Once the rod is pounded into the ground you need a little more than a "pencil iron" to join the copper wire / woven brain to the ground rod.  Simple mechanical clamps seem to be accompanied by a lot of wishful thinking when it comes to a long lasting low-resistance connection.
