Coaxial cable Rangeful RG58/U 50 Ω N male to SMA male, 7 m

Coaxial cable Rangeful RG58/U 50 Ω N male to SMA male, 7 m is a flexible RF interconnect designed to transmit signals between devices with N-type and SMA-type connectors. The cable uses RG58/U construction with a nominal 50 ohm impedance, offering a balance of flexibility and stable characteristic impedance for antenna connections, test instruments and radio systems. At seven metres length it allows placement of equipment at a practical distance while maintaining signal integrity for many short- to medium-range RF applications.

Advantages

This 7 m RG58/U coaxial cable combines a standard 50 Ω impedance with male N and male SMA terminations to enable direct connection between differing RF interfaces without adapters. The RG58/U core and shielding provide consistent impedance control and reduce mismatch losses over the cable length. Its flexible jacket simplifies routing in confined spaces and permits easier deployment during tests and temporary installations. The robust connectors ensure repeated connect/disconnect cycles with reliable mechanical and electrical contact.

Suitable for

• Connecting antennas to transceivers or amplifiers with N and SMA ports
• Laboratory and field RF measurements where N-to-SMA interconnects are required
• Short-range radio systems and test bench connections
• Temporary installations and equipment setup during maintenance or diagnostics

Key specifications

• Cable type: RG58/U coaxial
• Impedance: 50 Ω nominal
• Length: 7 m
• Connector A: N male
• Connector B: SMA male
• Recommended use: RF signal transmission for low- to mid-frequency ranges
• Construction: center conductor with dielectric, braided shield and outer jacket for flexibility

How to use

Inspect connectors and cable for visible damage before use. Align the N male connector with the mating N female port and engage carefully until fully seated; attach the SMA male by threading and tightening the SMA coupling nut by hand, followed by light torque with an appropriate wrench if required to ensure secure contact without over-tightening. Route the cable to avoid sharp bends, kinks and proximity to high-power AC lines to minimise interference. For measurement tasks, use the cable as part of the calibrated signal path and account for expected insertion loss in readings.

Usage recommendations

Store the cable coiled without tight twists and avoid crushing the connectors. For critical RF measurements, verify connector cleanliness and consider performing a short verification of insertion loss or return loss to confirm expected performance before final measurements. Replace the cable if the outer jacket or connectors show wear that could affect impedance or contact quality.
