The MikroTik ACMMCXRPSMA is a compact MMCX-to-RPSMA RF pigtail cable designed to connect compatible MikroTik wireless cards and radio interfaces to external RPSMA antenna connections. MikroTik originally designed it particularly for adding a second wireless interface to products such as BaseBox2 and BaseBox5. (mikrotik.com)
The cable measures 260 mm, or approximately 26 cm, making it short enough to minimize unnecessary internal cable length while still giving installers sufficient flexibility when routing between an internal MMCX connector and an enclosure-mounted RPSMA connection. (mikrotik.com)
MikroTik currently lists the ACMMCXRPSMA at a suggested manufacturer price of US$9, and it remains in the current MikroTik accessories range. (mikrotik.com)
MikroTik's official specification confirms the 260 mm cable length, MMCX-to-RPSMA design, US$9 suggested price and approximately 100,000-hour MTBF at 25°C. (mikrotik.com)
What Is MikroTik ACMMCXRPSMA?The ACMMCXRPSMA is a radio-frequency pigtail, not an Ethernet cable or power cable.
A typical connection looks like:
Wireless card MMCX connector → ACMMCXRPSMA → RPSMA external antenna connector
It is especially useful when a MikroTik device contains an internal miniPCI or miniPCIe wireless card but the installer wants to expose its antenna connection outside the enclosure.
MikroTik's current compatibility list includes both older and newer wireless hardware, including R11e-series cards, RB912 boards, BaseBox products, L11UG-5HaxD and L23UGSR-5HaxD2HaxD.
Key Features of MikroTik ACMMCXRPSMAThe main purpose of ACMMCXRPSMA is to convert an internal MMCX RF interface into an accessible RPSMA connection.
This makes it suitable where:
The wireless card has MMCX connectors.
The antenna system uses RPSMA.
The radio sits inside an enclosure.
An external antenna connection needs to be brought through the enclosure.
The cable measures 260 mm. (mikrotik.com)
This relatively short length is useful in radio enclosures because excessive RF cable length can introduce unnecessary attenuation.
MikroTik specifically describes the pigtail as suitable for adding a second wireless interface to BaseBox2 or BaseBox5. (mikrotik.com)
Historically, MikroTik demonstrated an example in which a second miniPCIe wireless card was installed inside a BaseBox and connected through ACMMCXRPSMA cables, allowing the device to support multiple wireless bands. (device.report)
A current 2026 MikroTik catalogue describes ACMMCXRPSMA as compatible with most MikroTik miniPCI and miniPCIe wireless cards that use the appropriate MMCX connector. (Ring Ring Energy)
Compatibility should still be verified because some newer cards use different connectors such as U.FL.
MikroTik's current ACMMCXRPSMA product page lists these devices and cards among its related products.
5. Useful for Dual-Band BaseBox ConfigurationsOne of the classic applications of ACMMCXRPSMA is adding another wireless card to a BaseBox.
For example, MikroTik previously demonstrated:
BaseBox2 + R11e-5HnD + two ACMMCXRPSMA pigtails
to create a dual-band outdoor access point capable of operating on both 2.4 GHz and 5 GHz. (device.report)
The exact combination should always be checked against current RouterOS, radio-card and regulatory compatibility.
6. Compact Installation Inside EnclosuresThe 26 cm cable is compact enough for routing inside wireless enclosures without creating excessive cable loops.
Good internal cable management helps avoid:
Sharp bends
Connector strain
Cable pinching
Contact with inappropriate components
Difficult enclosure closing
ACMMCXRPSMA requires no electrical power.
It has:
No PoE
No DC input
No CPU
No RouterOS
No firmware
No IP address
It simply carries RF signals between the connected wireless card and antenna interface.
8. Does Not Increase Antenna GainThe pigtail does not itself increase:
Antenna gain
Radio transmit power
Receiver sensitivity
Wi-Fi speed
Wireless range
Its role is to provide the physical RF connection.
The quality of the complete wireless link depends on the radio, antenna, frequency, cable loss, connector condition, antenna alignment and environmental conditions.
Common Applications in KenyaThe ACMMCXRPSMA is particularly useful for WISP installations, outdoor wireless access points, custom RouterBOARD deployments and legacy BaseBox installations where an internal MMCX wireless interface needs to connect to an external RPSMA antenna.
It can also be used in campus networks, CCTV wireless backhaul, rural broadband installations, hotels, farms and enterprise wireless projects where compatible MikroTik radio cards and external antennas are deployed.
For installers repairing or upgrading older BaseBox and RouterBOARD equipment, ACMMCXRPSMA can also be useful as a replacement pigtail where the original connector cable has been damaged.

The accessory is available through networking and MikroTik suppliers in Kenya. Since current local prices vary significantly, confirm ACMMCXRPSMA, the 260 mm length and MMCX-to-RPSMA connector arrangement before ordering.
Installing MikroTik ACMMCXRPSMAInstallation starts by identifying the correct MMCX connector on the wireless card. The MMCX end of the pigtail should be connected carefully and without excessive force. The RPSMA bulkhead side is then secured in the appropriate antenna opening of the enclosure, allowing the external antenna or antenna cable to be attached.
When working with multi-chain wireless cards, ensure each radio chain is connected correctly. Avoid sharp bends, crushing the cable or placing tension directly on the small MMCX connector. Internal RF connectors can be damaged if the cable is repeatedly pulled or twisted.
After installation, confirm that the appropriate antennas are attached before transmitting with the wireless card. The radio configuration, wireless band, antenna gain and regulatory settings remain controlled by RouterOS and the actual radio hardware; ACMMCXRPSMA itself requires no configuration.
The MikroTik ACMMCXRPSMA is a simple but important RF accessory for connecting an MMCX wireless-card interface to an RPSMA external antenna connection. Its compact 260 mm length makes it particularly suitable for BaseBox and RouterBOARD installations where internal RF connections need to be routed through the enclosure.
It is especially useful for adding or connecting compatible wireless cards such as the R11e and older miniPCI series, and MikroTik's current compatibility list also includes newer boards such as L11UG-5HaxD and L23UGSR-5HaxD2HaxD. Because the pigtail is passive, it requires no power, software or RouterOS configuration.
