If the far end is left un-terminated the BOG will not work well as I have found here. Try a small ground rod of 4 feet and a 250 ohm resistor and sweep again. I predict your results will be much bett

One nice trick I have used in the past to locate buried radials and check them for continuity is to walk around the radial field with a good professional FSM (field strength meter) tuned to station's

Probably it will work very good if you establish a ground on both ends with some spiders like radials. 3 or 4 about 60 feet long or longer should do it. Herb Schoenbohm, KV4FZ On 4/26/2017 1:44 PM, A
