The MikroTik ACSMAUFL is a compact RF pigtail cable designed to connect a modem or wireless card with a U.FL connector to an external antenna using an SMA female connector. MikroTik specifically positions it for LTE, LoRa and wireless-card applications, making it useful in RouterBOARD and IoT installations that require an external antenna.
The cable is especially relevant to MikroTik devices such as wAP R, LtAP mini and compatible R11e-series LTE cards. MikroTik also lists accessories such as SMASMA and mANT LTE 5o alongside ACSMAUFL, allowing installers to build a complete external-antenna connection.
MikroTik currently lists ACSMAUFL at an official suggested price of US$9. A dependable current Kenyan retail price for the exact ACSMAUFL was not confirmed during the latest check, so buyers should request the current Kenya quotation rather than rely on an estimated conversion.
MikroTik's official specification identifies ACSMAUFL as a U.FL-to-SMA female pigtail intended to connect an LTE, LoRa or wireless modem/card to an external antenna. It also lists an MTBF of approximately 100,000 hours at 25°C. (mikrotik.com)
What Is MikroTik ACSMAUFL?The ACSMAUFL is a radio-frequency pigtail, not an Ethernet, USB or power cable.
A typical installation looks like:
LTE/LoRa/Wireless card → U.FL → ACSMAUFL → SMA female → External antenna
The U.FL connector attaches to the small RF socket on the modem or radio card. The SMA female bulkhead connector provides an accessible external antenna point.
This arrangement is useful where a modem is located inside a router enclosure but the antenna needs to be mounted outside the enclosure or in a better signal location.
Key Features of MikroTik ACSMAUFLThe primary function of ACSMAUFL is converting a small U.FL modem connector into a more practical SMA female external antenna interface. (mikrotik.com)
This is useful because U.FL connectors are typically located directly on LTE, LoRa or wireless cards and are too small for repeatedly connecting external antennas directly.
MikroTik specifically lists LTE equipment among the intended uses of ACSMAUFL. (mikrotik.com)
It can be useful when:
An LTE modem is installed inside a MikroTik enclosure.
The internal antenna position gives poor reception.
A higher-gain external LTE antenna is required.
The antenna needs to be positioned outside a cabinet.
ACSMAUFL is also designed for compatible LoRa radio cards. (mikrotik.com)
This makes it relevant for:
IoT gateways
Smart metering
Agricultural sensors
Industrial monitoring
Remote telemetry
Environmental monitoring
MikroTik also describes ACSMAUFL for compatible wireless cards with U.FL connectors. (mikrotik.com)
The important requirement is that the radio card actually uses U.FL. MMCX-based cards require a different pigtail such as ACMMCXRPSMA.
MikroTik's current product page lists wAP R, R11e-LTE, R11e-LTE-US, LtAP mini, LtAP mini LTE kits, mANT LTE 5o and SMASMA among related products. (mikrotik.com)
5. Useful with wAP RThe wAP R is one of the most important ACSMAUFL applications.
MikroTik's own accessory guide shows ACSMAUFL cables connecting an R11e-LTE card inside a wAP R to external SMA antenna connectors.
This allows installers to use an external LTE antenna where better signal reception or antenna positioning is required.
6. Useful with LtAP miniMikroTik lists several LtAP mini models as related products for ACSMAUFL. (mikrotik.com)
These devices may be deployed in:
Vehicles
Remote monitoring
Mobile internet
GPS and telemetry
Industrial IoT
Fleet connectivity
ACSMAUFL gives installers a practical route from the internal modem connector to an external antenna.
7. Passive AccessoryACSMAUFL requires no electricity.
It has:
No PoE
No DC input
No USB power
No CPU
No RouterOS
No IP address
No firmware
It only carries radio-frequency signals between the modem and antenna connection.
8. Does Not Amplify LTE or LoRa SignalsACSMAUFL is not an amplifier.
It does not directly increase:
LTE transmit power
LoRa transmit power
Antenna gain
Cellular speed
Wi-Fi power
Receiver sensitivity
Its value is allowing the correct external antenna to be connected to the modem.
Common Applications of MikroTik ACSMAUFL in KenyaACSMAUFL is useful for LTE installations where a MikroTik router needs an external antenna to improve antenna positioning. This can be particularly useful in rural, industrial or indoor locations where the router itself cannot be placed where cellular reception is strongest.
It is also useful for IoT and LoRa deployments, including remote sensors, smart metering, agriculture, telemetry and industrial monitoring. By exposing an SMA female connection, installers can use an appropriate external antenna rather than relying on a small internal antenna.
For vehicle, fleet and mobile installations using compatible LtAP mini hardware, ACSMAUFL can also make it easier to place LTE antennas externally while keeping the router securely mounted inside the vehicle or enclosure.

Yes. It remains listed in MikroTik's current accessories and LTE/5G product ranges at US$9.
You can source ACSMAUFL from MikroTik networking suppliers in Kenya. Confirm the exact ACSMAUFL U.FL-to-SMA female product before ordering, especially because several MikroTik antenna pigtails use similar-looking connectors.
Installing MikroTik ACSMAUFLInstallation begins by opening the compatible MikroTik enclosure and locating the U.FL antenna connector on the LTE, LoRa or wireless card. The U.FL end of ACSMAUFL should be aligned carefully and pressed straight onto the modem connector. Because U.FL connectors are very small, excessive force or sideways pressure should be avoided.
The SMA female bulkhead side is then positioned in the appropriate enclosure opening and secured so that the external antenna can be connected without placing mechanical stress on the internal modem. In dual-chain LTE installations, two ACSMAUFL cables may be needed to connect both antenna interfaces.
After the external antenna is installed, cable routing should be checked for sharp bends, excessive tension and unnecessary RF cable length. The modem, RouterOS configuration and external antenna determine the actual network performance; ACSMAUFL simply provides the reliable physical RF connection between them.
The MikroTik ACSMAUFL is a practical RF pigtail for converting the tiny U.FL antenna connection found on LTE, LoRa and compatible wireless cards into an external SMA female interface. It is particularly useful for MikroTik wAP R, LtAP mini and R11e-LTE installations where an external antenna is required.
Its passive design means there is no power, software or configuration to manage. By exposing a standard SMA antenna connection, ACSMAUFL makes it easier to deploy external LTE or LoRa antennas in rural connectivity, IoT, telemetry, vehicle, CCTV and industrial networking applications.
