RP-SMA-female to MHF4 Cables

Antenna Cable: MHF4 To RP-SMA female (bulkhead): Length options: 1-inch, 2-inches, 4-inches and in 2-inch increments up to 20 inches.

One end has a MHF4 connector, and the other end has a RP-SMA female connector with a bulkhead-mount.


RP-SMA Female connector includes a bulkhead nut and washer:

Characteristics and Specification of a RP SMA Female Connector Coaxial Type

You can use this to mount the connector (and thus the cable) on the wall of an enclosure (to weatherproof the cable connection), case or Printed Circuit Bard (PCB).

  • Weatherproofing: Seal the hole where the female connector is mounted, by placing an O-ring between the wall of the enclosure and the bulkhead nut & washer on the female connector.
  • The length of our standard RP-SMA-female connector (threaded part) is 3/8 inches. We have a longer option: 14.5mm, which we can use for special orders.

MHF4 connectors' materials composition

RP SMA Connector Material Composition

RP-SMA is a round screw-type connector, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz: This antenna cable is compliant for all types of wireless antennas, including WiFi & WiMAX networks: Wi-Fi 6, WiFi 6E, 802.11AX, 802.11N, AC, G, A, B. 900MHz, 2.4GHz & 5GHz applications, ISM, GSM, LTE antennas, as well as any other frequency between 0 and 18GHz.

Cable is 1.13mm mini-coaxial cable (50 ohm antennas and cables.): This is a very thin and flexible cable, with a black jacket. When connecting U.FL connector to a jack on a miniPCI card or board, often the tight space requires the use of 1.13mm cable, because it is very thin and flexible (diameter is 1.13mm). This very thin cable is typically needed in tight spaces inside of enclosures, so that the U.FL connector will snap down on the jack without popping off.

Our MHF4 to RP-SMA series coaxial cables have medium-sized, threaded coupling connectors designed for use from DC to 11 GHz. Their consistently low broadband VSWR have made them popular over the years in many applications.

MHF4 miniature RF coaxial connector is the smallest mini RF connector in the world. Only 1.2mm low profile, MHF4 IPEX/IPX connector provides good working performance in various application of Wireless LAN.

Constructed with advanced mechanical-components and supreme-grade Teflon coax cable, Delivers high electrical performance of typical 1.3 max V.S.W.R. at 6.0 GHz, while providing for a sturdy interconnection engagement in a slim form factor of 2.0mm x 2.0mm footprint by 1.2mm mated height.
  • Space Economy: 2.0mm x 2.0mm PCB footprint, mated height of 1.2 mm
  • Teflon Cables: Silver plated center conductor, Teflon dielectric and jacket
  • PCB socket: Integral molded construction ensures product reliability.
  • Sturdy connection: Lead-in and interlock features among mating pair ensure solid coupling.
  • Accessory: Insertion/Extraction tool, test adapters for connection to MCH cable head and PCB connector.

MHF4 connectors are the smallest mini RF connectors ever made for coaxial antenna cables. Their low profile of only 1.2 mm means that they provide good working performance in a variety of Wireless LAN applications.

MHF4 connectors and cable assemblies provide stable frequencies of 0 to 6GHz and 50 Ohms of characteristic impedance. They are made of copper alloy, which is then plated with gold which further enhances their effectiveness. They are also highly flexible and will allow 360-degree mounting of the cable. The connectors can be terminated in 1.13 and 1.32 and coaxial cables.

With their small size and high operational frequency ranges MHF4 connectors can be used for a variety of Bluetooth and wireless LAN applications in gaming equipment, test points, mobile phones, access points, GPS, notebook computers, and wireless communication devices.


COMPATIBILITY: RP-SMA-female Connector fits items that have an RP-SMA-male jack/connector. RP-SMA = Reverse Polarity SMA

The MHF4 to RP-SMA series cable is impedance matched to 50 ohm cables.

    You Gotta Know What You're Doing

    Posted by Fred on 21st Aug 2017

    My motherboard specifies to use a M.2 type Wli-Fi module. The module I purchased included neither the 2 antennas needed nor the wires to connect them to the module.

    Therefore, I bought a standard antenna kit, which included 2 antennas and the wires to connect them to a Wi-Fi module.

    At the time, I didn't know there are two nearly-identical standards for Wi-Fi antennas. The wires that came with the standard antenna kit I bought didn't fit the connections on the M.2 Wi-Fi card. They fit only non-M.2 cards.

    The antennas themselves in the kit I bought work with either type wire standard, however. Thus, all I needed to do was to find a two-wire set that fit the M.2 Wi-Fi module I bought. Confusing!

    You have to understand (I didn't) the specs to know what you're buying, because the two types of connecters are not interchangeable. The connections on a M.2 Wi-Fi card are much smaller than those on non-M.2 cards. Who knew?

    The wires with the smaler connectors that fit the newer M.2 cards are called MHF-4 connectors, and that's where I went wrong.

    The bigger problem is that none of the sites I looked at specify what standard they're using with their antenna kits. This fact is a bit mind-boggling.

    Using Google I found Data Alliance. They had the wires I needed to get the job done. I ordered the wires and they arrived timely.

    You gotta know what you're doing. Ha!
