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
