🔍 Key Concepts

• Relationship between AZ (azimuth) movement, EL (elevation) movement, and how an antenna normally acquires a satellite • Purpose of a level platform sensor (or gyro/tilt sensor) in keeping the antenna correctly oriented • What component an I.F. (intermediate frequency) amplifier affects: signal strength vs. physical movement

💭 Think About

• When the antenna points straight up and stops, which part of the system controls whether the antenna is allowed to continue moving or tracking? • Does a failure in an AZ motor, EL motor, or I.F. amplifier usually cause a mechanical pointing problem, a signal amplification problem, or both? • How would a faulty level/tilt sensor "think" the antenna is oriented, and what would the control system do as a safety or default response?

✅ Before You Answer

• Identify which options affect physical rotation (AZ/EL axis) and which affect sensing/feedback or signal only • Consider whether both axes seem to move initially or if the description suggests only one axis responding • Ask: if the system stops with the antenna straight up, is it likely reacting to a bad orientation/level input rather than a burned-out motor or RF amplifier

The antenna tries to initialize then points straight up and stops. What is the most likely problem?

A defective EL motor.

A defective AZ motor.

A defective level platform sensor .

A defective I.F. amplifier.
