B757 RADOME (P/N db3) - As Removed

The db3 is a Boeing 757 radome—the composite nose structure that shields the weather radar antenna from environmental exposure while maintaining aerodynamic efficiency. Constructed from RF-transparent composite material, it allows radar signals to transmit and receive without degradation. Installed at the aircraft nose, this radome protects the radar dome from moisture, ice, and physical damage during flight operations.

Installation requires verification against your aircraft's Illustrated Parts Catalog and adherence to Boeing maintenance procedures.
