## Summary description

Flexible 20 m coaxial cable Rangeful RG58-RPTNCM-SM-20 with 50-ohm impedance, featuring SMA male to RP-TNC male connectors. Designed for RF signal transmission and antenna connections where RG58-type cable and SMA/RP-TNC interfaces are required. Suitable for test setups, radio equipment, repeaters and installations needing a reliable 50 Ω connection over a longer run.

## Long description

Rangeful RG58-RPTNCM-SM-20 is a flexible 20-meter coaxial cable with 50 Ω characteristic impedance, terminated with an SMA male connector on one end and an RP-TNC male connector on the other. The cable uses RG58-type construction to provide consistent RF transmission over a longer run while maintaining mechanical flexibility for routing in test benches, radio equipment racks, or antenna installations. The combination of SMA and RP-TNC interfaces makes it compatible with a wide range of transceivers, repeaters, and measurement instruments that require these connector types.
Advantages
This coaxial cable offers stable 50-ohm impedance and low insertion loss appropriate for short to medium RF runs. The RG58 construction balances flexibility and shielding, allowing easier cable management in confined spaces. Gold-plated mating surfaces on the SMA and RP-TNC connectors ensure reliable electrical contact and corrosion resistance. The 20 m length provides extended reach without intermediate adapters, reducing connector transitions that can degrade signal quality.
Suitable for
 Connecting antennas to radio transceivers and repeaters
 Test and measurement setups in laboratories and workshops
 Temporary or permanent RF link installations requiring SMA to RP-TNC interface
 Field equipment and portable radio systems with matching connector types
Key specifications
 Cable type: RG58-style coaxial
 Impedance: 50 Ω
 Length: 20 m
 Connector A: SMA male
 Connector B: RP-TNC male (reverse polarity TNC)
 Construction: flexible jacket suitable for indoor routing
 Suitable frequency range: typical VHF/UHF and lower microwave bands (dependent on system requirements)
How to use
Before use, inspect connectors and cable jacket for visible damage. Hand-tighten the SMA and RP-TNC connectors onto the mating ports and ensure proper seating; avoid over-tightening with tools to prevent connector damage. Route the cable to minimize sharp bends and avoid placing it near high-power mains cables or strong EMI sources. For installations where the cable will be fixed, secure it with appropriate clamps or ties at intervals to prevent undue strain on the connectors. Verify continuity and RF performance with appropriate test equipment after installation.
Usage recommendations
For optimal performance, keep bend radii larger than the cable’s minimum specification, avoid repeated flexing at the connector joints, and limit exposure to moisture and chemical contaminants. If the application requires very low loss at higher microwave frequencies, consider a lower-loss cable type or a shorter run. Regularly check connector mating surfaces for contamination and clean with a suitable, non-abrasive cleaner when necessary.
