Coaxial Cable Rangeful SMA Male to RP‑TNC Male RG58/U 50Ω 0.3 m

Rangeful coaxial cable SMA Male to RP‑TNC Male RG58/U 50Ω 0.3 m is a short, flexible RF jumper designed for 50 ohm systems. Constructed on RG58/U coaxial, this 0.3 meter cable provides a compact connection between devices requiring an SMA male interface and a reverse‑polarity TNC male (RP‑TNC male) interface. Its small length reduces signal loss and cable clutter in setups such as antenna connections, measurement equipment, routers and cellular modems.

Advantages

The cable combines standard SMA male and RP‑TNC male terminations on a proven RG58/U dielectric to ensure mechanical stability and consistent impedance matching. Its 50 Ω characteristic impedance is suitable for a wide range of RF equipment, helping to maintain signal integrity at common wireless frequencies. The 0.3 m length offers minimal insertion loss while providing sufficient flexibility for tight installations. Connector housings are designed for straightforward hand tightening or tool-assisted mating, enabling reliable and repeatable connections.

Suitable for

• Connecting antennas to routers, modems and access points
• Short jumper links between test instruments and DUTs in benchtop setups
• Replacing or extending antenna leads on cellular modems and wireless modules
• Tight-installation RF routing inside racks, enclosures or devices

Key specifications

• Cable type: RG58/U coaxial
• Characteristic impedance: 50 Ω
• Length: 0.3 m
• Connector A: SMA male
• Connector B: RP‑TNC male (reverse‑polarity TNC male)
• Flexible construction suitable for short jumper applications

How to use

Ensure both mating connectors are clean and free of debris before connection. Align the SMA male with the SMA‑compatible female and gently engage the threads until hand‑tight; avoid over‑torquing. For the RP‑TNC male connection, align and push the center pin into the corresponding female interface and tighten the outer coupling nut according to the equipment manufacturer’s guidance. Route the cable to avoid sharp bends and pinch points that could damage the dielectric or shielding. For measurement tasks, keep the cable as short as practical to minimize added loss and reflections.

Usage recommendations

Store the cable in a dry environment and avoid repeated flexing at the connector junctions. When used in RF measurement or antenna deployments, verify system performance after installation and replace the jumper if visual wear or degraded signal is observed.
