N FEMALE Connector

N Family

Type N is a threaded RF connector rated from DC to 18 GHz with a durable weatherproof design, making it the preferred interface for outdoor antenna installations, cellular base stations, and commercial wireless infrastructure. Its larger size compared to SMA allows higher power handling and the threaded coupling resists vibration, making it suitable for mobile and fixed outdoor applications.

Typical Applications

Outdoor cellular and LTE antennas, base station feedlines, cellular repeaters, public safety radio, marine and aviation equipment, commercial wireless infrastructure.

Gender & Polarity Note

Check the product datasheet for gender and polarity details. RF connectors are available in male (pin), female (socket), and reverse-polarity (RP) variants.

Frequently Asked Questions

What frequency range does the N FEMALE connector support?

N connectors are rated DC – 11 GHz. The effective upper frequency of a cable assembly is limited by the lowest-rated component — either the cable or the connector. Always verify both are within spec for your target frequency.

How many times can a N connector be mated and unmated?

N FEMALE connectors are rated for approximately 500 mating cycles. Exceeding this can cause wear on the contact surfaces, increasing insertion loss and VSWR. For applications with very frequent connects and disconnects, consider a connector rated for higher cycle counts.

What torque should I use to tighten a N connector?

Type N and TNC connectors should be tightened to 12–15 in-lb (1.36–1.70 N·m). Use a proper torque wrench for repeatable, reliable connections.

Are the N connectors on CoaxRF assemblies weatherproof?

Our standard cable assemblies use high-quality connectors suitable for most indoor and sheltered outdoor applications. For fully weatherproof outdoor installations, we recommend applying self-amalgamating tape over the connector junction to prevent moisture ingress.

Do CoaxRF cables with N FEMALE connectors ship assembled and tested?

Yes. Every cable assembly — including those terminated with N FEMALE connectors — is hand-assembled and continuity tested before shipping. Cables ship free within the US from our US facility.
