How Ground Radials Impact Your Vertical Antenna
A quarter-wave vertical is only half an antenna. Here is why ground radials matter so much, and how the number and type you use changes your performance.

80 and 160 Meters: Low-Band DX After Dark
The low bands reward patience, big antennas, and staying up late. Working DX on 80 or 160 meters is genuinely one of the most challenging and satisfying pursuits on all of HF.

How to Build a Wire Dipole Antenna for HF on a Budget
A simple, cheap half-wave dipole is still one of the best-performing HF antennas you can build. Here’s how to cut, build, and tune one for under $30.

Fan Dipoles: One Feedline, Multiple Bands
A fan dipole solves the multi-band problem with an approach that’s almost embarrassingly simple: instead of one antenna trying to cover several bands through traps or compromise, you just hang several resonant dipoles off the same feed point. The concept A fan dipole is exactly what it sounds like: multiple individually cut, resonant half-wave dipoles,…

Building a 9:1 Unun for a Random Wire HF Antenna
A random wire is the cheapest, most flexible HF antenna there is, as long as you pick the length carefully and match it right. Here’s the 9:1 unun build.
