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.
- 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.
- This is an embedded antenna, not a sealed outdoor assembly. Review the enclosure, ground plane, cable routing and connector clearance. Cable length or routing changes require engineering confirmation.
- No IP rating is specified in this source. Do not assume sealed outdoor suitability; confirm the installation and environmental requirements.
