Check the manufacturer's interface definition and mating geometry, including center contacts and coupling arrangement. Thread appearance alone can be misleading.
How it works in practice
Standard and reverse-polarity variants can look similar while having different center-contact arrangements. Use exact part descriptions and drawings. Do not force components together if the contacts or threads do not match. Verify both ends of inline accessories before purchase.
Example and interpretation
An SMA and an RP-SMA interface can have superficially similar coupling hardware without the expected center-contact pairing.
Checks before use
- Read the exact interface designation
- Inspect contacts
- Check both ends
- Use compatible parts
Important limit
A connection that appears to screw together is not proof of a correct RF mate.
