My BOG was operating well at 1.8 MHZ before it became compresses under a mass of weeds and vegetation causing the resonance to go lower in frequency. (similar to a covered wire having a lower velocity factor than the same wire when bare.)
Fashioned a hook at the end of an old mop handle, easily pulled the wire up to the surface, and the BOG is "right back to normal". On most soil, a BOG will resonate to 160 meters using ~ 200 feet. There are variances with soil difference. Length can be adjusted for the optimum front to back when terminated. Termination resistance varies with soil, I start with 235 ohms . 73
