To: <towertalk@contesting.com> It all depends on what it is that you are trying to measure. The above is fine for determining the connection resistance of one ground rod to earth. These rods are use
Ah! A testimony to poor planning! ;-) You would probably be better off overall to route the feedlines to the service entry first, do the ground panel there, and then route them to the shack. But if
