As an experiment last week, I decided to see what was the resistence between my grounds were in the yard. I have 9 grounds. 4 of them are for the matching transformers feeding the four pieces of coax from the NW/NE/SW EWEs and the Beverage. Then I have the 4 grounds at the ends where they are terminated and finally the receiver ground. Two of the antennas come in close to each other, the SW EWE and the Beverage. The other two are separated 30-50 feet away. I ran the meter from the two grounds (SW EWE & Beverage) separated by a couple of feet. I found 5,000 ohms. I then checked the ground from the SW EWE to the NE EWE. Those grounds are separated by 40 feet. I found 5,000 ohms. With our soaking wet soil and the swamp in the field and our water table is above the surface much of the year, there is probably nothing I can do to raise that 5,000 ohms. In experimenting I disconnected the grounds from everything except the antenna I was using. I also monitored the signal out in the yard and see can tell no difference. No change in pattern or nulls. Nothing. I am sure the resistance has always been the same since I moved out here in 1981, so I guess it isn't anything to be concerned about. Even if it made a difference, the only thing I could do it to go back to one antenna. I would like having 100K between grounds, but that is not likely out here.
