Identifying a Reverse-Polarized Connector
Figure A - 6. Reverse Polarity and Straight connectors
A reverse polarized coaxial connector alters the standard connector interface by utilizing a male pin
center conductor in a female threaded coupling mechanism and 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.
