The antenna goes past the AZ EL of the satellite but does not initialize but you can manually point the antenna at the satellite and acquire signal. What is the most likely problem?
ā¢ Automatic satellite tracking and initialization in marine stabilized antennas ā¢ Role of the antenna control unit / control module (ACU) vs. RF path components like coax and I.F. amplifiers ā¢ How AZ/EL position sensors and heading/gyro inputs affect auto-pointing
ā¢ If you can manually point and receive a strong signal, what does that tell you about the condition of the RF chain (coax, I.F. amplifier, LNB, etc.)? ā¢ Which component is responsible for automatically driving the antenna through its search pattern, detecting lock, and declaring initialization? ā¢ Would a problem with heading/gyro feedback prevent the antenna from tracking after lock, from finding the satellite, or from passing the AZ/EL position at all?
ā¢ Confirm in your mind which parts are involved in signal carriage (moving the RF signal) versus control and positioning (moving the dish). ā¢ Identify which failure mode matches the symptom: passes the satellite in AZ/EL but does not stop/lock automatically, yet works when manually positioned. ā¢ Eliminate any options that would cause no signal even when manually aimed at the satellite.
