Hello Luis,   The BOG wire is not the gauge of the wire, but the impedance. Many transformer  suppliers are using 150 ohms.   BOG antennas react with the earth it rest (sits) upon. The BOG length to

Yes, basically true, but in my case most of the noise is coming from one direction. Antennas with deep nulls have allowed me to work DX. Also use a MFJ-1026 to help with nulls.   We are drifting towa
