Coaxial cable SMA-W/N-G+H155-0.2 — RF jumper with SMA/W and N connectors, H155 0.2 m

Coaxial cable SMA-W/N-G+H155-0.2 is a compact RF jumper designed for short, low-loss interconnections between equipment with SMA/W and N female/male interfaces. Built on H155 (RG-179 family) coaxial construction and measuring 0.2 m in length, this cable provides consistent characteristic impedance and controlled attenuation for applications requiring precise signal transfer over a short distance. The cable is suitable for laboratory bench work, field measurements and permanent or temporary installations where space is limited.

Advantages

This RF jumper combines the small form factor of H155-type coaxial with industry-standard SMA/W and N connectors to offer a balance of flexibility and electrical performance. The short 0.2 m length minimizes insertion loss and reduces the potential for signal reflections, while robust connector terminations ensure repeatable mating cycles. The construction yields stable characteristic impedance and shielding adequate for many test and RF signal routing tasks.

Suitable for

• Connecting RF test instruments to antennas or fixtures
• Interfacing repeaters, transceivers and radio modules
• Short patch connections in laboratory and production environments
• Field measurements and temporary setups where compact cabling is required

Key specifications

• Coaxial type: H155 (RG-179 family)
• Length: 0.2 m
• Connector A: SMA/W
• Connector B: N
• Application: RF signal jumper for low-loss, short-distance connections

How to use

Inspect both connectors and mating ports for debris before connection. Align the SMA/W and N connectors with their respective mating interfaces and hand-tighten where required; use an appropriate torque wrench if precise torque is specified by connected equipment. Route the cable to avoid sharp bends and mechanical strain; maintain gentle curvature consistent with the H155 coaxial bend radius. When disconnecting, support the connector bodies to avoid stressing the cable termination.

Usage recommendations

For best performance, avoid routing near high-power cables or sources of electromagnetic interference and do not exceed manufacturer-recommended bending radius. Store the cable coiled loosely and protect connector ends with dust caps when not in use.
