The W8JI Super Mini Loop antenna is a compact full-wave loop design that delivers multi-band HF performance. Learn how it works, why it’s efficient, and how to build and optimize it for your stati
Tag: 80 meter antenna
The 80-meter band (3.5 MHz) is a cornerstone of HF amateur radio for regional and nighttime communication. This section covers practical 80 meter antenna designs including dipoles, verticals, magnetic loops, and compact multiband HF antennas for real-world installations and limited-space stations.
A Compact 4-Meter Vertical Antenna for the 80-Meter Band
Build a compact 4-meter vertical antenna for the 80-meter band. This DIY guide features a high-efficiency loading coil design and a top-hat capacity spoke system to make 80m operation possible in small yards and restricted spaces
Half Loop Antenna for 80, 40, 20, and 15 Meter Ham Radio Bands
Can’t fit a full-sized 80-meter dipole in your backyard? Or maybe you’re tired of the high noise floor of a vertical? It’s time to look at the Half-Loop. This “open-loop” design provides a fantastic balance between the quiet reception of a loop and the simplicity of a wire antenna.
In this project, we explore a multiband Half-Loop configuration that covers everything from 80 meters down to 15 meters. We’ll discuss the radiation pattern, the importance of a good ground or counterpoise, and how to use a simple tuner to jump between bands. If you’re looking for a “stealthy” antenna that punches above its weight on the low bands, this build is for you. Let’s get that wire in the air!
Multiband Dipole Antenna for 10–80 Meters
Compact multiband HF dipole covering 10–80 m using symmetrical loading coils and coax matching section. Single-wire antenna for small spaces enabling 80, 40, 20, 15, 11, and 10 m operation with an antenna tuner.
