MikroTik Flex-guide ACRPSMA – RP-SMA Antenna Pigtail Adapter

The MikroTik Flex-guide is a 50 cm coaxial cable with RP-SMA connectors, designed for low-loss connections between wireless equipment and external antennas in installations where RF signal quality is critical. The silver-plated copper inner conductor and hand-soldered connectors — not crimped — deliver losses below 0.65 dB across the full length, outperforming standard crimped-connector cables of the same format.

The difference between soldering and crimping is significant in RF applications: soldered connectors provide continuous electrical contact and superior mechanical durability over time, while crimping can introduce impedance variations and oxidation points that degrade signal quality in the long term. The silver-plated copper conductor maintains optimal conductivity and corrosion resistance for both indoor and outdoor use under varying humidity conditions.

The 50 cm length and cable flexibility allow easy routing inside BaseBox enclosures or other confined technical spaces without excessive bends that would affect impedance. Compatibility with standard RP-SMA connectors covers BaseBox, NetMetal, Groove, and any other MikroTik or third-party product with RP-SMA connectors. The Flex-guide name combines "flexible" and "waveguide" to reflect performance above standard coaxial cables.

It is the right fit for installations where every dB in the link budget matters — particularly for equipment with external antennas where the interconnecting cable is a controllable loss factor, for BaseBox users connecting miniPCI-e wireless cards to external antennas who want to minimize losses compared to standard cables, for outdoor deployments where the corrosion resistance of silver-plated copper ensures stable long-term performance, and for any RF scenario where the build quality of soldered connectors is preferred over volume-crimped alternatives.
