Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily for radio communication rather than navigation
Antenna parts for aircraft radio transmission/reception fall under Chapter 85 radio equipment rather than navigational instruments.
If for use in other measuring or checking instruments
Couplers adaptable to non-aviation precision measurement may classify under broader measuring instrument parts.

Import Tips & Compliance
• Verify TSO (Technical Standard Order) authorization from FAA for the specific VOR navigational equipment compatibility
• Include frequency response test data in customs documentation to substantiate navigational appliance classification
• Avoid common pitfall of declaring as general antenna without civil aircraft specificity, which could trigger reclassification
