or even just a random wire vertical antenna. All of these will need to be connected feedline of some sort, and in the likely event you reach for some 50-ohm coax cable you’ll also need a balun ...

Baluns find wide use in mixer, antenna and balanced amplifier circuits. Yet balun design is still regarded as if it were black magic by many engineers partly due to the fact that practical design ...

His recent video shows how to put up a workable basic HF antenna in a small backyard. The center of the system is a 49:1 unun. An unun is like a balun, but while a balun goes from balanced line to ...

Written for practicing engineers new to the field, this book includes a succinct treatment of wireless designs with enough detail that CAD formulas may be implemented with relative ease.
