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 .
