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
Understanding the distinction between Baluns, Ununs, and Common-Mode Chokes is a rite of passage in RF engineering and homebrewing. These devices all manipulate RF currents and impedance, but
In an amateur radio antenna system, a counterpoise acts as an artificial radio-frequency (RF) ground. It is essentially the “other half” of an unbalanced antenna, designed to complete
“Short skip” refers to ionospheric propagation where radio signals refract back to Earth at distances much shorter than the typical “skip distance” for a given frequency. It effectively
Exploring the microwave and millimeter-wave (mmWave) bands is often considered the final frontier of amateur radio. Unlike the HF bands where ionospheric skip dictates the day, the spectrum
When deploying emergency communications (EMCOMM) under austere field conditions, the priority shifts from chasing low-angle DX to establishing rock-solid, predictable local and regional circuits. An emergency antenna system
