Identifying a Reverse-Polarity Connector
Figure A - 6. Reverse Polarity and Straight Connectors
A reverse-polarity polarized coaxial connector alters the standard connector interface by using a
male pin center conductor in a female threaded coupling mechanism with a female basket center
conductor in a male threaded coupling nut mechanism.
This prevents mating with a standard non-polarized connector. This type of connector is required by
FCC part 15.203 rules for modular approval. See Appendix C on page 43.
