Terry, A ground loop exists if there is a large amount of wire hanging in the air acting as an antenna to which the ground is the counterpoise. You should run #8 Stranded Bare Copper Wire (75' is about $30 at Wirenco) either in the ground or buried about 2 inches below the grass (like you can do with a radial, except not bare wire for the radial). You should bond all of your ground rods together this way so that all grounds are a common potential. Ground all of your equipment to a single point inside the shack, and run the shortest piece of wire from that common point to a ground rod as close to the house and shack as possible. This will limit the potential of ground loops. I use #8 rubber-coated automobile audio ground cable to make that run.
