[Antennas] Ground rod questions (Ground currents)

[Loren Moline WA7SKT]

I have seen where there were bad connections to the neutral due to the fact that the neutral conductor in a aerial cable for instance was aluminum and was spliced to copper so an oxide built up in the connection causing a resistive splice.

When the tide was out, those were the funny things we would observe with metering we installed at OUR service entrance.  (Scrounged from an old abandoned power plant.)
