Coaxial Cable Rangeful RG58-RPTNCM-NM-20 50 Ω, N male to RP-TNC male, 20 m

Rangeful RG58-RPTNCM-NM-20 is a 50 Ω coaxial cable with a length of 20 meters, fitted with an N male connector on one end and a reverse-polarity TNC (RP-TNC) male connector on the other. The cable uses RG58-type construction suitable for RF signal transmission, offering standardized impedance to help minimize reflections and impedance mismatch in radio, antenna and test setups. This assembly is intended to extend or interconnect equipment that requires N and RP-TNC interfaces in laboratory, field and installation environments.

Advantages

The cable provides consistent 50 Ω impedance along its length to maintain signal integrity across frequencies commonly used in radio and test equipment. Durable coax construction combined with industry-standard N and RP-TNC connectors ensures reliable mechanical and electrical connections. The 20 m length offers flexibility for remote placements and routing in installations without the need for multiple shorter jumper cables. Materials and connector design support repeated connections and disconnections while reducing the risk of signal loss due to poor mating.

Suitable for

• Extending RF connections between devices with N and RP-TNC interfaces
• Laboratory test setups and measurement rigs
• Field installations for antennas, repeaters and portable radio equipment
• Temporary or permanent wiring in communication system deployments

Key specifications

• Impedance: 50 Ω
• Length: 20 m
• Cable type: RG58-style coaxial construction
• Connector A: N male
• Connector B: RP-TNC male (reverse-polarity TNC)
• Typical use: RF signal transmission for radio, antenna and test equipment

How to use

Connect the N male end to the corresponding N-female port and the RP-TNC male end to the reverse-polarity TNC female port on the mating device. Ensure connectors are properly aligned before hand-tightening; apply appropriate torque where specified by the equipment or connector manufacturer to avoid damaging connector threads. Route the cable to avoid tight bends, sharp kinks and prolonged mechanical strain; maintain minimum bend radius consistent with RG58-style cable to preserve signal performance. Inspect connectors for cleanliness and secure seating before powering RF equipment or running tests.

Usage recommendations

For best performance, avoid excess bending and repeated torsion at connector junctions, keep the cable dry and free from corrosive contaminants, and verify connector cleanliness before each connection. When used in critical measurement setups, consider performing a quick continuity and return-loss check to confirm signal integrity after installation.
