Reverse Polarity Adapters
Reverse polarity adapters are commonly used in wifi systems. Offered now are sma reverse polarity adapters and tnc reverse polarity adapters. The FCC mandated the use of reverse polarity interfaces, with pins & dielectrics switched, so as to prevent unintended hookups of non certified equipment; today reverse polarity adapters are commonly available. We find reverse polarity TNC and reverse polarity sma interfaces to be the most common.
