MikroTik ACUFL Network Adapter – Female Connector

MikroTik ACUFL is a 385 mm pigtail cable with a U.fl-HIROSE connector on one end and an N-female connector on the other, designed for connecting external antennas to wireless cards R52H and R11e-2HnD that feature a U.fl internal connector. Commonly used in indoor and outdoor installations where miniPCI wireless cards require external N-female antennas to improve coverage or signal directionality.

The total length of 385 mm including connectors provides sufficient routing slack inside RouterBOARD enclosures without excessive stress on the U.fl connector on the board. The N-female output connector ensures compatibility with the wide range of external antennas and coaxial cables with standard N-male connectors used in professional wireless installations. Connection quality is critical in RF applications — the cable maintains minimal signal loss across its full length.

ACUFL is specifically compatible with R52H and R11e-2HnD cards, ensuring correct mechanical and electrical fit for the U.fl connectors on these models. Adding or replacing external antennas through this pigtail allows wireless performance optimization without changing the radio card, useful in scenarios where the internal antenna provides insufficient coverage or where a directional external antenna is needed for a specific link.

Recommended for installations with R52H or R11e-2HnD cards where connecting an external N-female antenna is needed to improve wireless coverage, for RouterBOARD enclosures with N-female Bulkhead connector openings where the pigtail bridges the radio card to the external connector, and for integrators optimizing RF performance of existing installations by adding directional or high-gain external antennas.
