Building the Shorty 4020 Antenna for 40M and 20M Operation

Space has always been one of the biggest challenges in amateur radio. Full-size HF dipoles work well, but not everyone has enough room for long wire antennas stretched across a backyard. That’s exactly where the Shorty 4020 antenna becomes interesting.

The Shorty 4020 is a compact dual-band dipole designed for 40 meters and 20 meters. Its biggest advantage is simple: it reduces the physical size normally required for a 40m dipole while still providing respectable HF performance.

For apartment operators, portable activators, and anyone dealing with restricted installation space, this antenna has gained a solid reputation over the years.
