What is the maximum degree range that the AN/MPN-14K LCC airport surveillance radar (ASR) antenna can be tilted?

The maximum degree range that the AN/MPN-14K LCC airport surveillance radar (ASR) antenna can be tilted is 0 to +10 degrees. This specification is essential for ensuring that the radar can effectively scan the airspace within its designated operational limits while avoiding unnecessary ground clutter and focusing on the primary targets of interest.

The limited tilt range allows the radar to maintain optimal performance in tracking aircraft at low altitudes without compromising the accuracy of the radar returns. By keeping the tilt at this range, the system can more accurately assess the altitude and location of approaching and departing aircraft, which is crucial for airport safety and air traffic management.

Choosing a tilt range beyond +10 degrees, as indicated by the other options, would not align with the operational design and functional capabilities of the AN/MPN-14K LCC system.
