Product details

The Amphenol RF 031-6802 is a reverse-polarity TNC (RP-TNC) plug with a female centre socket, designed for field-termination on RG-58 coaxial cable. The RP-TNC interface swaps the gender of the centre contact compared to a standard TNC — the plug body carries the female socket, while the mating jack carries the male pin. This is a common interface in Wi-Fi and ISM-band antenna systems where regulatory requirements dictate reverse polarity. The connector is rated for 50 Ohm impedance and operates up to 6 GHz, covering 2.4 GHz and 5 GHz bands comfortably. It is intended for free-hanging (in-line) use with a threaded coupling nut for vibration-resistant mating.

Termination and cable prep — crimp shield, solder centre

The dielectric is PTFE, which holds up to the 165°C upper operating limit and maintains stable impedance through the cable-to-connector transition.

Durability and environmental range

No gasket or sealing is specified in the listing; for outdoor installations where moisture ingress is a concern, a weatherproof boot or sealed mating jack should be used.

Frequently asked questions

Is the Amphenol RF 031-6802 a 50 ohm or 75 ohm connector?

The 031-6802 is a 50 Ohm connector, as listed in the specification. This matches the standard impedance for RG-58 cable and is the correct choice for 50 Ohm RF systems (Wi-Fi, cellular, ISM-band radios).

What cable does the 031-6802 work with?

It is designed for the RG-58 cable group. The shield is crimped, and the centre conductor is soldered. Prepare the cable per the manufacturer's crimp dimension sheet for RG-58 to ensure proper impedance transition and pull-off strength.

Is 031-6802 a male or female connector?

The connector type is a plug with a female centre socket. In RP-TNC terminology, the plug body has internal threads and the centre contact is a socket (female). It mates with an RP-TNC jack (male centre pin, external threads).
