[TowerTalk] SPG=1 or More Rods?

[Phil Camera]

You mention a ground right at the tower and another grounded bulkhead
at the house entrance. That sounds like two grounds to me. Why do you
call one of them a Single Point Ground when there are clearly two?


Bill, good question.  In your example above the bulkhead ground at the house entrance is considered the SPG.  SPG is misleading because it can be more than one ground rod; what it refers to is the cable entrance location at the shack/house entrance.  Personally I have three ground rods spaced about 3 feet apart for my SPG.  The entire grouping is my SPG or where all my cables come together and connect to arrestors prior to entering into my house.
