Key Takeaways:

Aircraft experienced various antenna failures, predominantly affecting GPS systems, but also ELT and ADF components.
Common causes of these failures included internal faults, improper OEM installation leading to water intrusion and corrosion, and physical separation of antennas.
Operational impacts were significant, ranging from total GPS signal blockage and loss of navigation during critical flight phases to uncontrolled cabin pressurization and a single faulty GPS antenna jamming all other onboard GPS devices.
