Reactance in Antennas Explained! Understanding XL, XC, and Why it Matters for SWR! Following on from Antenna Impedance, we now explore Reactance – the second crucial component of that electrical opposition! What exactly is Reactance, where does it come from in your antenna, and why is it a major factor in SWR and tuning? This reel breaks down this essential concept for every ham radio operator. In this video, we cover: Defining Reactance: The opposition to changes in current or voltage caused by

This simulation shows the voltages across the components in a series RLC circuit driven by an AC source of 1 kHz frequency. The circuit includes a resistor (R = 100 Ω), an inductor (L = 10 mH), and a capacitor (C = 1 µF) connected in series. The graph at the top displays the instantaneous voltages across R, L, and C along with the supply voltage. The resistor voltage (green) is in phase with the current, the inductor voltage (red) leads the current by 90°, and the capacitor voltage (yellow) lags
