Coaxial cable Rangeful RG58/NM-SM-3 50 Ω, 3 m

Rangeful RG58/NM-SM-3 is a 3 m coaxial cable with a characteristic impedance of 50 ohms, manufactured to RG58 specifications for RF and signal transmission. The cable is intended for short runs where standardized impedance and consistent signal transfer are required. Its construction supports connections between antennas, amateur and professional radio equipment, test instruments and other low-power RF devices where a 50 Ω feedline is necessary.

Advantages

The cable delivers a consistent 50 Ω impedance to minimize signal reflections and maintain signal integrity over short distances. Its 3 m length is convenient for many indoor and bench setups without excess slack. Constructed according to RG58 standards, it offers predictable electrical characteristics and straightforward compatibility with BNC, TNC or other 50 Ω connectors when terminated appropriately. The design balances flexibility and physical durability to facilitate routing and handling in compact installations.

Suitable for

• Connecting antennas to transceivers for amateur radio and VHF/UHF equipment
• Linking RF test equipment, signal generators and spectrum analyzers in laboratory setups
• Short indoor cable runs between low-power transmitters and accessories
• Temporary or bench installations where a 3 m length is convenient

Key specifications

• Impedance: 50 Ω
• Length: 3 m
• Cable type: RG58 construction
• Primary application: RF and signal transmission for low-power devices
• Mechanical: flexible jacket suitable for indoor routing

How to use

Prepare compatible 50 Ω connectors or use pre-terminated cable ends suitable for the devices in use. Ensure connector mating surfaces are clean and that connectors are tightened to the appropriate torque if applicable. Route the cable avoiding sharp bends and tight kinks; maintain bend radii consistent with RG58 practice to prevent deformation of the conductor or dielectric. For test and measurement environments, keep cable lengths as short as practical to reduce loss and use proper calibration or reference measurements when precise results are required.

Usage recommendations

Use the cable indoors or within protected installations to avoid exposure to prolonged moisture, UV light or mechanical abrasion. When connecting to sensitive RF equipment, verify connector type and impedance match at both ends; consider using adapters only when they preserve the 50 Ω characteristic. For longer runs or higher-power applications, evaluate higher-grade or lower-loss coaxial options suited to the specific frequency and power requirements.
