Join Greg Algieri, WA1JXR, for a special Friday afternoon Introduction to “Impedance, SWR and Transmission Lines” at the 2026 Northeast HamXposition.
The presentation will introduce the amateur to what complex impedance is, how to measure it, how the Impedance is related to my SWR, how this all applies to transmission lines, and how the waves and power travel from your transceiver to your antenna.
