Coaxial cable Rangeful SMA Male to RP‑TNC Male RG58/U 50 Ω 0.5 m

Rangeful SMA Male to RP‑TNC Male RG58/U 50 Ω 0.5 m is a compact coaxial cable intended for short RF interconnections. Constructed on RG58/U coaxial core with a nominal 50 ohm impedance and a length of 0.5 m, it provides a flexible connection between equipment featuring an SMA male interface and devices using a reverse‑polarity TNC (RP‑TNC) male connector. The cable is suitable for antenna leads, portable radios, lab test setups and quick prototyping where a reliable, low‑loss 50 Ω link is required over a short distance.

Advantages

The cable offers a short, flexible 0.5 m assembly that minimizes signal loss and cable clutter in tight installations. The RG58/U construction provides predictable impedance for RF applications and compatibility with a wide range of 50 Ω devices. The use of an SMA male connector on one end and an RP‑TNC male connector on the other enables direct mating between equipment with these specific interface types without adaptors. Its compact size and standard 50 Ω characteristic make it convenient for bench testing and temporary connections.

Suitable for

• Connecting antennas to devices with SMA or RP‑TNC interfaces
• Portable radios, routers and wireless modules with differing connector types
• Laboratory test rigs and measurement setups requiring short coax leads
• Prototyping RF circuits and quick functional checks

Key specifications

• Cable type: RG58/U coaxial
• Characteristic impedance: 50 Ω
• Connector A: SMA male
• Connector B: RP‑TNC male (reverse polarity TNC male)
• Length: 0.5 m
• Typical usage: RF signal interconnect for frequencies used in common radio and test equipment

How to use

Ensure both mating connectors on equipment are clean and undamaged before connection. Align the SMA male thread and engage gently until hand‑tight; avoid cross‑threading. For the RP‑TNC male, align the centre pin carefully with the device's RP‑TNC female and tighten by hand as required. Do not overtighten connectors; finger tight is usually sufficient for temporary and bench connections. Route the cable to avoid sharp bends and kinks that can increase losses or damage the dielectric.

Usage recommendations

Use the cable for short‑range RF connections where a direct SMA-to‑RP‑TNC link is needed. For permanent outdoor installations or higher power applications, choose cables and connectors rated for environmental protection and power handling. Regularly inspect connectors for wear and replace the cable if shielding or connector integrity is compromised.
