What is an N-Type Connector?

N-Type connectors are the most common type of radio frequency (RF) connectors for coaxial cables. These hardy connectors can conduct ultra-high radio frequencies of up to 18 GHz and withstand voltages of up to 3000 VRMS. N connectors are also weatherproof and watertight – which means you can install antennas with this connector on rooftops or mounting poles outside.

Which Antennas Use N-Type Connectors?

N-Type connectors are standard to connect coaxial cables with other cables or equipment, so many booster antennas have an N connection. These boosters include both directional and omnidirectional antennas, as well as a wide range of models within these two categories.

The Super Digital Yagi Antenna is a Yagi antenna with an N connection. This type of antenna consists of multiple elements mounted perpendicularly along a central rod. While one or two of these elements are active “driven” elements that send and receive signals, most of the elements are passive “reflectors” or “directors” that direct the signal towards a driven element.

The Super Periodic Log Yagi Antenna is a log periodic antenna with an N connection. This type of antenna has the same basic build as a Yagi antenna, but all of its elements are usually active. This type of antenna can conduct signals across a wider frequency range than Yagi antennas.

The 4G LTE Panel MIMO Antenna is a directional panel antenna with an N connection. These antennas are flat (often aluminum) panels that shield two dipole antennas: one that conducts vertically polarized signals and one that conducts horizontally polarized signals. One of the key components of this model is a strong reflector plate that concentrates both types of signals.

What are the networking specifications of an N connector?

Maximum RF 11 GHz or 18 GHz
Maximum dielectric voltage 3000 VRMS
Voltage Standing Wave Ratio (VSWR) 1.3:1
Impedance 50 OHMS, 75 OHMS
Shielding effectiveness < -100 dB
Temperature range -67° F to +325° F


What are the mechanical specifications of an N connector?

Outer diameter (Male) 0.827 inches
Outer diameter (Female) 0.627 inches
Connector thread 5/8″-24 UNEF


How Do N-Type Antennas Connect to Cables?

N-Type connectors contain an outer conductor, an air gap, and a threaded inner conductor that carries internet signals. There are two types of N connectors: male and female. The male connector or “plug” has a threaded center pin, while the female connector or “jack” has a threaded inner sleeve. To connect cables with N connectors, insert the plug into the jack.

It’s usually pretty easy to connect the plug and jack of an N-Type connector since most don’t use hex nuts. To fasten the connection in place, manually turn the male connector clockwise to tighten it.

Are N-Type Antennas Compatible with Internet Routers?

Most internet equipment manufacturers – including NetGear and Linksys make internet routers that have SMA connectors. While these connectors conduct RF signals pretty much the same way as N connectors, the two connectors don’t have compatible specifications. For example, SMA connector plugs are 0.312 inches in diameter and N plugs are 0.827 inches in diameter.

Luckily, the cables that come with booster antennas typically have an N connector on one end (for the antenna) and an SMA connection on the other end (for the router). In this case, it isn’t usually necessary to use a coaxial adaptor to transform an N connector into an SMA connector.
