Re: [IRCA] BOG question

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.

I don't see the self-terminating thing.


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.

Have you had success terminating a BOG Russ?   (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
