Extra exam question E9G03
Subelement E9, ANTENNAS AND TRANSMISSION LINES· Group E9G
Which of the following is often determined using a Smith chart?
- A.Beam headings and radiation patterns
- B.Satellite azimuth and elevation bearings
- C.Impedance and SWR values in transmission lines (correct answer)
- D.Point-to-point propagation reliability as a function of frequency
WhyA Smith chart is often used to determine impedance and SWR values in transmission lines. A Smith chart is often used to determine impedance and SWR values along transmission lines, translating between load impedance, line length, and the resulting SWR and impedance seen at different points, answer C. Beam headings, satellite azimuth/elevation, and point-to-point propagation reliability are separate antenna-orientation and propagation topics, not what a Smith chart is built to calculate.
