The GWX 75 features a primary high-density connector. Wiring must comply with FAA Advisory Circular AC 43.13-1B/2B regarding aviation-grade shielding and grounding practices. Power Requirements
+/−60∘positive / minus 60 raised to the composed with power yaw scan limits.
Before you begin the installation process, make sure you've completed the following steps:
Verify no foreign objects or tools are left in the radome bay. Ensure the antenna moves freely without hitting structural walls. gwx 75 installation manual
If utilizing turbulence detection or ground clutter suppression, ensure the appropriate configuration settings are applied in the installation tool. 5. Configuration and Calibration
Never look into an open waveguide or unattached connector while the system is powered. Mechanical Installation Steps

Before beginning the installation, technicians must consult the official Garmin for the latest revisions, regulatory requirements, and certified data. Structural Considerations
The relay pack (or contactor) is the switch that sends power to the motor. It must be mounted securely and close to the winch. Secure the relay pack to the motor or frame using the band clamps.
The GWX 75 uses attitude data from the aircraft’s AHRS (Attitude and Heading Reference System) to stabilize the radar image, ensuring that the antenna stays focused on the weather even if the aircraft pitches or rolls. Connect the ARINC 429 input to the aircraft AHRS. 4. Configuration and Calibration Before you begin the installation process, make sure
Adjust the and Roll Trim electronic offsets on the screen until the radar level matches the AHRS level. Save the configuration to the system's non-volatile memory. 5. Post-Installation Testing
Ensure there is enough clearance for the antenna to rotate freely ( 120∘120 raised to the composed with power 90∘90 raised to the composed with power
