How often should the antenna weather cover be inspected during PMCS?

The correct choice indicates that the antenna weather cover should be inspected weekly during preventive maintenance checks and services (PMCS). Regular inspection is crucial to ensure that the weather cover remains intact and free from damage, which is essential for the radar's operational integrity. An undamaged cover protects the antenna from environmental hazards such as rain, snow, and debris, all of which can impair its performance. By adhering to a weekly inspection routine, operators can identify and address any potential issues before they affect the functionality of the radar system, ultimately contributing to successful mission outcomes. This regular maintenance practice underscores the importance of proactive care for equipment in the field.
