Dick, There is not much to damage inside the Ham IV rotor itself as the wire-wound direction slider can take most induced RF from shunt feeding at normal amateur power levels. The indicator swing can

Having ready all the problems with various baluns that rate from junk to near junk I have been using the coiled cable to feed most antennas that require a balanced feed. I would like to hear what is

Thanks for all the wonderful suggestions (many off line) for a better balun than my BN-86's. I just ordered from Force 12 (Chip K7JA) their bead balun model EB-1 as this is easier for me to install o

Stacking dipoles like in the FM radio world produces significant gain of course. If the dipoles are of the same polarity and properly stacked and fed you can double your radiated power every time you
