## Summary description

3-meter coaxial cable by Rangeful with SMA male to RP‑TNC male connectors, built on RG58/U coaxial type with 50 Ω impedance. Designed for RF signal connections between devices with SMA and RP‑TNC ports, useful for antennas, routers, radio equipment and test setups. Provides standard impedance matching and flexible interconnection over a short run.

## Long description

Rangeful 3-meter coaxial cable with SMA male to RP-TNC male connectors is built on RG58/U construction and specified for 50 Ω systems. The cable provides a flexible link for RF signal transmission between devices with SMA and reverse-polarity TNC ports, suitable for short runs where impedance matching and signal integrity are required. The assembly is intended for use in antenna connections, routers, radio transceivers and laboratory test setups that accept SMA and RP‑TNC interfaces.
Advantages
The RG58/U core and 50 Ω characteristic impedance ensure predictable RF performance in VHF and UHF ranges commonly used by Wi‑Fi, amateur radio and other RF equipment. The SMA male and RP‑TNC male connectors offer secure threaded and reverse‑polarity mating to maintain mechanical and electrical contact. At 3 meters length the cable balances reach with acceptable insertion loss for many short to mid-range applications, while the flexible jacket and typical RG58 braid provide ease of routing in confined installations.
Suitable for
Connecting external antennas to routers, access points and gateways with SMA and RP‑TNC ports
Linking radio transceivers and receivers in amateur and commercial radio setups
Temporary interconnection and signal routing in RF test benches and laboratory environments
Prototyping and field deployments where a short, flexible 50 Ω jumper is required
Key specifications
Cable type: RG58/U coaxial
Characteristic impedance: 50 Ω
Connector A: SMA male (threaded)
Connector B: RP‑TNC male (reverse‑polarity threaded TNC)
Length: 3 m
Shielding: braided shield over dielectric (typical RG58 construction)
Typical applications: RF signal transmission in VHF/UHF bands, data and test connections
How to use
Verify that both devices accept the specified connector genders (SMA male and RP‑TNC male) and that a 50 Ω connection is appropriate for your system. Carefully thread the SMA connector onto the mating SMA female port until hand‑tight; do not overtighten to avoid damaging the connector. Align and engage the RP‑TNC male connector with the corresponding RP‑TNC female port, ensuring correct pin orientation for reverse‑polarity connections. Route the cable to minimize sharp bends and avoid tight coils; maintain gentle bend radii consistent with RG58 flexible cable to reduce risk of micro‑bending losses. After connecting, verify signal integrity and performance with appropriate measurement equipment or by functional testing of the connected devices.
Usage recommendations
For best RF performance, keep the 3 m run as straight as practical, avoid running the cable parallel to power lines, and minimize exposure to harsh environmental conditions. If you require lower loss over longer distances or different mechanical properties, consider alternative cable types or shorter/more direct routing. Handle connectors by the housing when mating and avoid pulling on the cable jacket to reduce stress on terminations.
