As I recall mine are typically in the hundreds of ohms or low thousands, never as high as 20k, even on a 950 ft wire.
I do see large variations of these across my 12 acres, even significantly different readings on each wire in a staggered phased pair. We have two different soil types, which may be a factor. My ground rods are typically 3-5 feet, and water table is usually a few inches deep or less. 73/Jon AA1K Sent from my iPhone > On Nov 15, 2016, at 9:20 AM, Herbert Schoenbohm <he...@vitelcom.net> wrote: > > I have reflection transformers at the end of every two wire Beverages which I > try to test by measuring the wires on the feed end.

I also have to such antennas made up of ladder line a DX Engineering components.
