## Moxon antenna calculator

Leslie Moxon, G6XN, invented a two-element in the 1950es, named after him. Less Moxon published an article in a QST magazine from 1952 titled Two-Element Driven Arrays describing his antenna.

## Building a Double Bazooka Antenna

A Double Bazooka Antenna is a broad-banded half-wave Antenna. This antenna can operate efficiently across an entire band without needing an antenna tuner. In the 1940es, the MIT staff designed and developed this antenna as a radar antenna for the military. Like a dipole, the Double Bazooka is a balanced …

It is often helpful to run tests and take measurements without connecting an antenna. Ham radio operators or anyone who builds or experiments with radio transmitters should have a good dummy load. Since I didn't have such a device, I decided to make one. Dummy Load In radio, a dummy …

## Measure a capacitor using an oscilloscope

In my last article, I showed how to measure an inductor using a known capacitor. This method could be used to measure a capacitor using a known inductor. This post will demonstrate a better and more accurate way to measure a capacitor using an oscilloscope. Usually, a capacitor's value is …

## Measure an inductance or capacitance using an oscilloscope

Resistors, inductors, and capacitors are passive components used in every electronic circuit. Usually, the value is marked on the resistor or capacitor, either as a color code or a number. Often, inductors have no markings, especially those with a ferrite core or an air core. To measure their value, professionals …

People think that all wires are the same and that any cable should be OK to power their rig. This is far from true, especially when you want to power your radio using a battery. This article focuses on installing a mobile radio or installing a battery backup for your …

## Antenna modeling software

I gave a presentation on antenna modeling software to a couple of clubs in California and Oregon. From the physical antenna design to the matching network, we designed the antenna live with the participants. Here is a little more about the talk: During the first part of the talk, we …
