Coaxial cable Rangeful RG58-RPSM-NM-3 50 Ω, 3 m

Coaxial cable Rangeful RG58-RPSM-NM-3 is a 50 Ω RF cable with a length of 3 m designed for reliable signal transmission in radio, antenna and test equipment. Built on RG58 construction, the cable offers the standard impedance matching required for most 50-ohm RF systems and provides flexible routing for installations where a short to medium length interconnection is needed between transceivers, antennas and measurement instruments.

Advantages

The cable combines RG58 characteristic impedance and consistent construction to maintain signal integrity across its 3 m length. Its connectors are configured for common RF interfaces, making it compatible with a wide range of 50 Ω devices. The cable’s flexibility simplifies installation in confined spaces and reduces stress on connectors, while the shielding design helps suppress external interference to preserve RF performance.

Suitable for

• Connecting transceivers and antennas in amateur and commercial radio setups
• Linking test and measurement instruments to antennas or signal sources in laboratories
• Temporary or permanent installations requiring 50 Ω impedance matching
• RF prototyping and bench work where a 3 m patch cable is convenient

Key specifications

• Characteristic impedance: 50 Ω
• Cable type: RG58-style coaxial construction
• Length: 3 m
• Frequency range: suitable for general RF applications (VHF/UHF and typical laboratory use)
• Connector configuration: standard RF male/female interfaces for 50 Ω systems
• Shielding: braided shield to reduce external interference
• Flexibility: moderate, suitable for routing and bench connections

How to use

Inspect connectors and cable for visible damage before use. Connect one end to the output port of your transceiver, signal generator or test instrument and the other end to the antenna or measurement device, ensuring secure threaded or push-fit engagement as required by the connector type. Route the cable to avoid sharp bends and pinching; maintain bend radii appropriate for RG58-style coax to avoid impedance changes. For measurement accuracy, keep cable runs as short as practical and avoid running parallel to large power cables that may introduce interference.

Usage recommendations

For improved long-term performance, periodically check connectors for corrosion and mechanical wear, and replace the cable if shielding or insulation shows degradation. When using in test setups, allow for a short warm-up period for connected equipment and minimize cable movement during high-precision measurements.
