Antenna

The Antenna category collects all of our HF, VHF, and UHF antenna designs in one place — from compact balcony loops to multiband wire antennas and portable verticals. You’ll find step‑by‑step builds for 80 m to 70 cm, including delta loops, trapped dipoles, doublets, magnetic loops, collinears, J‑poles, Moxons, and more, each with practical dimensions and matching options that actually work on the air.

Many designs are optimised for small plots, apartments, and portable operation, with notes on noise behaviour, radiation patterns, SWR results, and tuning tricks. Whether you are chasing DX on 40 m, experimenting on 6 m “magic band,” or improving repeater coverage on 2 m and 70 cm, this section helps you choose and build the right antenna for your station

94-Foot Multi Band Doublet Antenna – Simple All-Band HF Wire antenna

If you could only ever hang one wire in your backyard for the rest of your life, the 94-foot Doublet would likely be it. Often called the “all-bander’s dream,” this specific length is a classic in the Amateur Radio world for a reason: it’s short enough to fit in most yards, yet long enough to be highly efficient on the 80-meter band.

Unlike a standard dipole that’s stuck on one frequency, the Doublet uses balanced ladder line to turn your entire feed system into part of the antenna. In this guide, we’ll look at why the 94-foot length is the “sweet spot” for multiband performance and how to properly interface it with your tuner. Forget complex traps and multiple dipoles—one wire can truly do it all. Let’s get that ladder line hanging!

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!
