NMO Adapters To N-Female & N-Male

This adapter screws into the base of any NMO antenna, regardless of whether the NMO style is MABO (⅜ inch hole) or MBO (3/4 inch hole).

The adapter has a bulkhead, nut and washer, so that you can mount the adapter through a hole (such as a vehicle roof or the wall of an enclosure).

See our NMO-mount-compatible antennas (this adapter fits them):

• LTE antennas including Multiband LTE
• WiFi & BlueTooth NMO-mount compatible antennas
• 900MHz antennas for LoRaWAN, Helium & any application in the 890-915 MHz frequency band

NMO antenna bases, MABO and MBO: Key Points

• MABO (3/8" diameter version) and MBO (3/4" diameter version) are the two different types of through-hole NMO connector.
• NMO is a thru-hole mount type that is optimized for vehicular roof mounting of an NMO type antenna.
• NMO ring hole size: There is a 3/8" version and a 3/4" version.
  • MABO works with a ⅜ inch hole
  • MBO works with a ¾ inch hole

Broad Wireless Compatibility:
Support a wide frequency range (0GHz to 18GHz), maintain low broadband VSWR, and are precisely matched to 50 Ohm impedance—ensuring full compatibility with a wide range of wireless systems:

• Cellular networks: LTE / 4G, GSM / 3G, and WiMax for both data and voice
• WiFi standards: Including 2.4GHz and 8GHz bands—Wi-Fi HaLow 802.11AH, 802.11AX, 802.11AC, 802.11N, 802.11G, 802.11B, and 802.11A.Type-N adapters, connectors, and cables are frequently used in Wi-Fi systems. Devices using IEEE 802.11 standards—like 802.11ax, ac, g, n, and b—typically feature N-type-female connectors to attach external antennas, especially for outdoor usage.
• IoT & M2M applications: Bluetooth, ZigBee, WiFi HaLow, RFID, LoRa, LTE-m, and NB-IoT, WiFi 6, WiFi 6E.

ROHS & REACH compliant: All of our antenna cables and adapters are free of lead and the other toxic materials restricted by RoHS 3 and REACH.

N-Type Connector Characteristics and Details

N is the largest of RF connector types, and very common to see on large antennas (most large antennas have an N-female connector).

• N is nickel-plated brass, which is the best metals composition for rust-proof / corrosion proof / weatherproofing for long-term outdoor exposure.
• N-type connectors are usually rated up to 12.5GHz, making them usable in not just Wi-Fi applications, but also in the higher end of the microwave spectrum
• N-Female diameter is 0.620-inch (1.57 cm).

Adapter materials composition. Engineered for performance:

• Body: Nickel-plated brass delivers outstanding corrosion protection and rugged strength.
• Weatherproofing for long-term outdoor exposure
• Insulator: PTFE dielectric ensures reliable operation in electrically intensive environments.
• Ferrule: Copper core with nickel plating reinforces durability
• Contact: Gold-plated beryllium copper for premium conductivity and minimal signal disruption.
