Which cases contain the Antenna Columns on the AN/TPQ-50?

The correct choice indicates that cases 2, 3, and 4 contain the Antenna Columns on the AN/TPQ-50. This is based on the design and configuration of the artillery radar system, which requires a specific placement and arrangement of its components for effective operation.

In the context of the AN/TPQ-50, the Antenna Columns are crucial for deploying the radar system, as they facilitate the antennas’ optimal positioning to effectively detect incoming artillery and other projectiles. The inclusion of cases 2, 3, and 4 suggests that these cases are designated for transporting and housing the essential components that make up the Antenna Columns, ensuring they are secured during transport and can be quickly set up in the field.

Understanding this configuration is vital for operators to ensure they can assemble the radar system accurately and efficiently when deployed, which directly impacts the system's effectiveness in the field. Recognizing the importance of each case and its components helps ensure that the radar operator is fully prepared for any operational scenario.
