Title: Explain the function of fixed, diode-switching, and dual-feed feedhorns.
Course: Telecommunications I (10006-I) > Section: Examining Satellite Communication

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?
