– Think of a Light Bulb
Transmitter - Battery
Connection to Utility - Positive Lead
Ground Stake - Negative Lead

Bad Conductors
– Ductile/Cast Iron
– Rusted Pipe
Frequency to Metal Relationship
Good Conductors
– High or Low
Bad Conductors

How do we choose?? And why.
Can We Start YET???
Equipment Setup
