• About Reverse Polarity Series

Reverse Polarity non-standard interface connectors are designed for spread spectrum wireless applications where Part 15. 203 of U.S. FCC regulations are applicable. The reverse polarity design prevents damage and will not mate with standard interface devices if accidentally connected. SMA, BNC and TNC devices are readily available. Standard cable affixement sizes are available with special or custom design inquiries accepted.
