Coaxial cable Rangeful RG58 50 Ω 20 m — RP-TNC female to RP-TNC female

Rangeful RG58 50 Ω coaxial cable, 20 meters long, fitted with RP‑TNC female connectors at both ends. This cable is built for RF signal transmission where reversed‑polarity TNC interfaces are required, offering the familiar electrical characteristics of RG58 construction in a flexible, field‑friendly assembly suitable for antenna connections, test setups and short‑range RF links.

Advantages

The cable provides consistent 50 ohm impedance for proper RF matching and low reflection across common VHF/UHF frequencies used in communications and testing. Its RG58 geometry balances flexibility and mechanical durability, allowing easy routing in tight spaces and repeated handling without excessive stiffness. Reversed‑polarity TNC female connectors ensure compatibility with devices and antennas that use RP‑TNC interfaces while maintaining a secure threaded coupling for reliable connections.

Suitable for

• Connecting RF equipment and antennas with RP‑TNC female interfaces
• Laboratory and field test setups requiring a 20 m flexible RF lead
• Temporary or semi‑permanent links for VHF/UHF communications
• Extending existing coaxial runs where RG58 attenuation and flexibility are acceptable

Key specifications

• Characteristic impedance: 50 Ω
• Cable type: RG58 coaxial construction
• Length: 20 m
• Connector type (both ends): RP‑TNC female (reversed‑polarity threaded TNC)
• Typical use: RF/antenna connections, test leads
• Mechanical properties: flexible jacket suitable for routing and repeated handling

How to use

Connect each RP‑TNC female connector to the corresponding RP‑TNC male or adapter on your equipment, ensuring the threaded coupling is securely hand‑tightened to maintain a stable RF connection. Route the cable to avoid sharp bends and prolonged compression at corners; allow gentle arcs with radius greater than the cable diameter to preserve characteristic impedance and reduce microbend loss. For test setups, position the cable away from high‑power conductors and noisy electronics to minimize interference. When disconnecting, hold the connector body rather than pulling the cable to prevent stress on the termination.

Usage recommendations

Use this RG58 20 m lead for short to medium runs where flexibility and ease of handling are priorities. For lower insertion loss over longer distances or higher frequency applications, consider using a cable with larger conductor and lower attenuation characteristics. Store the cable coiled without tight kinks and inspect connectors periodically for corrosion or loose coupling to ensure reliable RF performance.
