NMO Mount Adapter to SMA-female Connector:

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):

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

Mounting / Installation Options:  Through-hole Mount, or use this L-bracket for wall mounting or pole mounting:  This L-bracket mount fits this antenna:  Simply remove the adapter (NMO to SMA) and then through-hole mount the antenna on the L-bracket.

Compatibility with wireless standards & applications: Our SMA cables range of frequency band compatibility (from 0GHz to 18GHz), consistently low broadbandVSWR, and impedance matching to 50 Ohm cables, makes them compatible and compliant for all the following applications:

  • Wi-Fi (WLAN): Suitable for WiFi & WiMax networks: WiFi 6, Wi-Fi 6E, 802.11AX, 802.11N, AC, G, A, B. 900MHz, 2.4GHz & 5GHz applications. A common application of N-Type adapters and connectors is in WiFi technology. Devices (operating on IEEE 802.11 standards (such as 802.11ax, 802.11ac, g, n, and b) often have Type-N-female connectors for external antennas - especially for outdoor applications.
  • Cellular Wireless LTE / 4G, GSM / 3G WiMax: Data and voice applications
  • IoT wireless, automation & Machine to Machine (M2M): Bluetooth, ZigBee, RFID, LoRa, LTE-m, NB-IoT

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

SMA Connector Characteristics:

SMA adapter materials composition

UHF Connectors

The UHF connector's body is made from machined, nickel-plated brass with a Teflon insulato. Though it is rugged and easy to handle and mate, it is not weatherproof, limiting its applications. The outside diameter of the mated connector is usually 18 millimeters but can vary.

The connectors have 5⁄8 inch 24 TPI UNEF standard threading

  • The male UHF connector has internalized threads and carries a brass conductor pin
  • The female UHF connector has externalized threads and carries a brass receptacle.
