Getting a solid grasp of Radio Frequency (RF) fundamentals is the first major step toward mastering the airwaves. Whether you are studying for your license or looking to
The Cobweb antenna (originally called the “Cobwebb” after its inventor, Steve Webb G3TPW) is a compact, multi-band HF antenna that provides omnidirectional, horizontally polarized radiation. It is highly
Amateur radio is one of the most effective, hands-on catalysts for steering youth into STEM (Science, Technology, Engineering, and Mathematics) careers. While it is often viewed simply as
Recently I had posted a video on satellite RX using my Moxon Yagi. One of the viewers suggested that I should check the antenna as the reception seemed
Dealing with noise is often the biggest hurdle in amateur radio, especially on the lower HF bands where the noise floor is notoriously high. Effective noise reduction isn’t
A Bazooka Balun (more commonly called a sleeve balun) is a type of 1:1 current balun made by placing a conductive tube or braided sleeve over the outside
A well-equipped test bench is the difference between guesswork and precision, especially when moving beyond basic operation into building and alignment. The modern shack doesn’t require racks of
Understanding basic electronics is the lifeblood of amateur radio, especially if you enjoy homebrewing your own gear, building linear amplifiers, or troubleshooting a newly minted transceiver. Here is
A capacitance hat (often called a capacity hat or “cap hat”) is a conductive structure—usually a set of radial spokes, a wire loop, or a metal disc—attached to
A loaded coil dipole antenna is a highly practical solution when you are severely limited by physical real estate. It uses inductors (coils) inserted into the antenna legs
