question

A low loss transmission line, operating at a frequency of 400MHz, with air as dielectric media, is used for radio transmission. Assuming negligible attenuation and 50\Omega characteristic impedance, calculate: (a) Reflection coefficient \Gamma (b) VSWR and (c) Wavelength of the transmitted signal.

options

  1. Reflection coefficient = 0.70 at -61.75 degrees, VSWR = 8.0, Wavelength = 0.80 meters
  2. Reflection coefficient = 0.80 at -61.75 degrees, VSWR = 9.0, Wavelength = 0.75 meters
  3. Reflection coefficient = 0.65 at -61.75 degrees, VSWR = 7.5, Wavelength = 0.78 meters
  4. Reflection coefficient = 0.60 at -61.75 degrees, VSWR = 7.0, Wavelength = 0.85 meters
  5. Reflection coefficient = 0.85 at -30 degrees, VSWR = 9.5, Wavelength = 0.68 meters
  6. Reflection coefficient = 0.90 at -61.75 degrees, VSWR = 10.0, Wavelength = 0.65 meters
  7. Reflection coefficient = 0.95 at -61.75 degrees, VSWR = 10.5, Wavelength = 0.60 meters
  8. Reflection coefficient = 0.50 at -45 degrees, VSWR = 6.0, Wavelength = 0.70 meters
  9. Reflection coefficient = 0.55 at -75 degrees, VSWR = 6.5, Wavelength = 0.82 meters
  10. Reflection coefficient = 0.75 at -90 degrees, VSWR = 8.5, Wavelength = 0.72 meters
