Key Takeaways:

Aircraft antenna failures, particularly with GPS systems, can lead to widespread issues including signal blockage, jamming multiple devices, and loss of critical navigation data.
Common causes of antenna failure include improper installation, inadequate sealing leading to water intrusion and corrosion, structural separation, and faulty seals impacting other aircraft systems like cabin pressurization.
These incidents highlight a need for enhanced abnormal procedure guidance for complex failures and potential antenna redesigns to prevent cascading system failures.
