Engineering confirmation before ordering
- Specifications are supplier-declared, not independent test certificates. Confirm the current revision, connector, mounting drawing and receiver compatibility before ordering. Phase center error is not a guarantee of positioning accuracy; request a calibration report or ANTEX file if your project requires one.
- Only the civil signal selection is presented. Confirm the orderable civil variant and current revision. Conflicting RF protection figures and an inconsistent LNA VSWR unit are excluded pending clarification; do not treat them as guaranteed limits.
- The ambiguous Galileo “E2” source label is not listed. L-Band is mentioned by the supplier, but compatibility with any correction service must be checked against its frequency, receiver and subscription requirements.
- IP67 is a supplier declaration for the specified assembly, not a certificate provided here. Confirm the connector seal, installation conditions and test evidence for your environment.
