". . . the overwhelming issue for many of us is local noise." Jim, have you tried low horizontal antennas? Even though their response to low-angle signals is inferior to that of verticals, they might

I borrowed a coil from QCoil Inductors to measure with my HP 4342A Q meter. This coil did not have the black, UV-resistant dielectric spreaders of production coils, but it was otherwise the same. Her

"I would guess that the measurement uncertainty (and modeling uncertainty) is sufficiently large that the modeled and measured are the same." Jim, inductance critically depends on coil diameter. But
