Coaxial cable SMA-W-RP/N-W+H155 5 m — SMA (reverse polarity) to N connector, H155 coax

Coaxial cable SMA-W-RP/N-W+H155 5 m is a 5-metre RF jumper built with H155 coaxial dielectric optimized for reliable signal transmission in antenna and radio equipment connections. One end has an SMA male reverse polarity (SMA-RP male) connector and the other end is an N female connector, providing a transition between compact SMA-RP interfaces and larger N-type installations. The cable is suitable for indoor and controlled-environment use where a flexible, low-loss connection is required over a medium distance.

Advantages

The H155 dielectric offers a balance of flexibility and stable electrical characteristics, keeping insertion loss relatively low across typical RF frequencies. The SMA-RP to N interface allows compatibility between consumer and professional devices without adapting the signal path excessively. The 5 m length provides convenient reach while maintaining manageable signal degradation compared with much longer cables. The cable construction ensures consistent impedance and straightforward installation between routers, radio modules, antennas and test instruments.

Suitable for

• Connecting routers or Wi‑Fi equipment with SMA-RP antenna ports to N-type antennas or feeders
• Linking radio transceivers and base stations where an SMA-RP to N transition is needed
• Temporary test and measurement setups with RF instruments that require an N female interface
• Indoor antenna installations and lab environments with medium-range cable runs

Key specifications

• Cable type: H155 coaxial cable with controlled dielectric
• Length: 5 metres
• Connector A: SMA male reverse polarity (SMA-RP male)
• Connector B: N female
• Impedance: 50 Ω nominal
• Typical application: RF signal transmission, antenna connections, test equipment linking

How to use

Ensure both mating connectors are clean and undamaged before making connections. Align the SMA-RP male carefully with the corresponding SMA-RP female port and engage by hand to avoid cross-threading, then tighten to the required torque if specified by device documentation. Connect the N female end to the N male on the antenna or equipment, securing the coupling nut by hand and final tightening as recommended by the equipment manufacturer. Avoid sharp bends and kinks in the H155 cable; maintain a bend radius larger than the cable diameter to preserve performance.

Usage recommendations

For best long-term performance, use this cable for indoor or sheltered applications and avoid exposure to prolonged moisture, UV or mechanical stress. When possible, minimize unnecessary cable length and use suitable torque tools or finger-tightening guidelines from device manuals to prevent connector damage. Periodically inspect connectors for corrosion or wear in active installations.
