Explanation should include
- describing linear and circular polarization
- describing fixed polarization orientation
- identifying pin diodes used for switching between horizontal and vertical polarization
- identifying circular polarization (clockwise and counterclockwise)
- converting from circular to linear polarization
- distinguishing between diode switching and dual feed
- diagramming diode switching and dual feed.
Process/Skill Questions:
- What is the difference between circular and linear polarization?
- How is polarization changed on an antenna?
- Why can two different signals be transmitted on the same channel/frequency?
- How is circular polarization converted to linear polarization? Linear to circular?
