Hi Tom, I'll give that a try. The FT1K MKV accepts a 0 to -4V external ALC input. It should a simple matter to hook up an external supply and then examine how an ALC "preset" voltage effects the lead

Good question, Ford. The impedance of free space describes the ratio of the electric field to the magnetic field for a propagating plane wave. IOW, if the electric field in a plane wave is 377 volts/

So, Tom, would it be safe to conclude from your analysis that there is no real benefit to shielding the loop? If the real benefit comes from the pattern, then shouldn't an unshielded loop properly is
