Testing Antennas (Short #188)
@ValGermer asks, how do you test an antenna? Well, there seems to be more to it than just using it and saying whether you like it or not, so how does Dave test antennas?

In this video, we sit down with Chris from Buddipole to take a first look at their revolutionary new wireless rotator system. This device replaces the traditional hand crank, allowing you to control your antenna’s azimuth directly from a phone, tablet, or laptop. One of the most exciting features is its ability to point directly to a POTA park or grid square with just a simple input. Whether you are a portable operator or looking for an easier way to manage your mast, this $295 wireless upgrade is set to be a game-changer for the ham radio community.

The Smith Chart Made EASY!
Learn about the Smith Chart, a fundamental tool for ham radio operators to visualize and understand complex impedance and reflection coefficient. The Smith Chart remains a standard RF tool, with its center representing a 50-ohm match and the outer boundary representing total reflection. It’s commonly used for antenna and feed-line impedance matching, helping to tune matching networks and move a load impedance toward the center of the chart for better power transfer. In this video, we’ll explore the basics of the Smith Chart, including constant-resistance circles, constant-reactance arcs, and normalization to a reference impedance. Whether you’re a seasoned ham radio operator or just starting out, understanding the Smith Chart is essential for one-port measurements and frequency-dependent impedance traces. Tune in to learn more about this essential tool and how to use it effectively for ham radio operations.
