Very good one Dave - One thing I really like about your videos is that they stick to the subject, are short but covers what needs to be covered. Too many others are not produced well; they ramble on wasting time until I get bored and just shut it down. Well spoken and informative is your norm, thank you sir. Bart, AA7VA
The exothermic welding system you mentioned is called.... Cad-Weld... It requires a mold sized to mate the wire size to the ground rod size. For example... 5/8" ground rod to #4 wire. It's important that the fit is fairly precise because the shot that starts in the top of the mold as a granulated power becomes a very thin liquid like water that flows into the part of the mold where the wire and ground rod are. This super heated liquid bronze literally melts the wire and ground rod together. When properly done. The weld will outlast the wire and ground rod...
Excellent video Dave, I've never seen a grounding resistance meter before, very interesting. Grounding an electrical system that produced RF is the single most important task one can do to ensure personal and equipment safety as well as a good solid signal.

Bear in mind, frost line can be 48 inches along great lakes
Your best ground is only as good as your worse..

Thank you, Dave.
