Coaxicom Reverse Polarity

Coaxial Components Corp. (best known as Coaxicom) – Stuart, Florida. February 18 – Recently we have noticed a significant increase in interest and inquiries regarding our reverse polarity connectors, in particular the SMA reverse polarity connector.

It seems that many in the telecommunications, network and wireless industries are using these R.P. connectors for either adaptations of existing equipment or completely new applications. In any case, reverse polarity appears to be making a big resurgence and is here to stay.

So what does reverse polarity really mean?  Many of us may have heard the term… but do we fully -understand what reverse polarity does.

In actuality, reverse polarity does not refer to the signal polarity but rather to the gender of the center contact.

Reverse polarity connectors were developed to abide by FCC rules and regulations. Originally intended for authorized purchasers only and not accessible to the general public, this was an attempt to prevent boosting, acquiring high gain components and blasting signals too far.

Today things have changed and now there are various reverse polarity connectors including non-magnetic reverse polarity that are readily accessible for all types of innovative designs, and advancements. And all are available at Coaxicom.

Basically in a reverse polarity SMA (RP-SMA) male connector there will be center socket not a center pin. This design adjustment is what makes it RP. It is also important to note that the threads are on the inside of the connector shell, same as the standard SMA male version. A word of caution…you should never “mix and match” standard and reverse polarity components.

So in a nutshell, it is actually the reversed center conductor gender not the polarity of the current that the name refers. And the descriptions of the “mating”  parts, “male” (internal thread and projecting center pin for SMA, N, etc.) and “female” (external thread, and center conductor socket for SMA, N, etc.) don’t really apply, as they do to the conventional connectors where the gender describes the form of the center contact. “Jack” and “Plug” are better terms, the RP-SMA “Jack” being the devise mounted end w/ the external thread and projecting pin, the “Plug” being the (typical) cable end or the antenna end, with internal thread and center socket.
