Making outline
- Machine selected metal coupled lines with air space and ceramic supports
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"New internal RF core; neither final antenna feed nor generic wire."
