Im planning to put up an inverted-L, using twinlead (akin to half a folded dipole some folks call it a folded unipole). Modeling suggests that the feedpoint impedance will be about 100 ohms, so I pla

I did some EZNEC modeling of a planned inverted-L, and came up with some results that surprised me, and caused me to re-think my understanding of Jerry Sevick's work. I modeled an inverted L over per

I'm considering a bead-based common mode choke for a 160m vertical. (I've got surplus 75 ohm CATV hardline that I thought I'd bury to keep it safe from the mower, and beads seem like an easy common m
