SWR - Standing Wave Ratio in antenna systems explained using physics.

I remember watching this AT&T video in engineering school. It was fun to find it again. Simple explanations of Standing Wave Ratio or SWR. Thanks WA7GTU for teaching me years ago in school and still today at radio club!

Dr. J.N. Shive of Bell Labs demonstrates and discusses the following aspects of wave behavior:
  • Energy loss by impedance mismatching
  • Reflection of waves from free and clamped ends
  • Superposition
  • Standing waves and resonance
  • Reduction of energy loss by quarter-wave and tapered-section transformers
Original audience: college students
Produced at Bell Labs
