3.4 Installation The GWX 70 is designed to be rigidly mounted in the nose section of the aircraft. If the nose section is not accessible, pod mounting is possible. The bulk head or antenna mounting plate must be very close to perpendicular to the aircraft center line. The selected location must have adequate clearance for the full antenna sweep and tilt range. See Appendix A for outline and installation drawings. The nose section does not need to be pressurized.

Installation
The GWX 70 is designed to be rigidly mounted in the nose section of the aircraft. If the nose section is not
accessible, pod mounting is possible. The bulk head or antenna mounting plate must be very close to
perpendicular to the aircraft center line. The selected location must have adequate clearance for the full
antenna sweep and tilt range. See Appendix A for outline and installation drawings. The nose section does
not need to be pressurized.
NOTE
It is crucial to the performance of the GWX 70 weather radar system that care be taken in
alignment of the GWX 70 unit with respect to the aircraft.
