4nec2: What does "#12/in" mean?
Yes, the wire gauges like #12 etc. are just predefined symbols that are the radius of that (AWG) gauge of wire, given in metric.
If you're using a GS card to specify dimensions in inches, then you nee …

GS cards in NEC decks
I'm pretty sure that what happens is that the GS card operates on everything above it and that they do "stack".
More specifically, whenever NEC reads a GW (or another card that defines wires like GH) …

NEC2: How do "currents" and "charges" inform antenna design and modeling?
"Charges" will tell you where the high-voltage points in your design are. If high-voltage points get too close to other parts of the structure that are at a different potential, or too close to much o …

Basic antenna matching theory?
Does this mean this antenna can't be tuned to the 160M band, or does this just mean that the impedance is so different from 300 ohms that the SWR is useless?
A little bit of both. If you get an o …
