My experience is exclusively on a sand beach. We found early on that a normal ground wouldn't work. We ultimately ended up with a fan of 4 radials through, IIRC about 220 ohms. We haven't been able to use BOG's since Hurricane Sandy several years back. We had one running up the coast ( 37 degrees) and the other down coast ( 217 ) and they were indeed directional at 800-1000 feet.
We even had success at 500' but the pattern was broader.

It seems to me (unscientifically) that the losses are maybe 5 to 7 dB. That's a far cry from the 30 or more dB loss in a properly terminated system.

(supposedly it is ~200 ohms, rather than the raised Beverage's ~450 ohms). I think some have found that it is self terminating, to a degree, as there is quite a bit of loss on reflected signals. best wishes, Nick At 20:07 2018-11-06, Russ Edmunds wrote: >It isn't a dumb question because the answer is yes and no.
