RG58 C/U - Standard 50 Ohm coaxial cable (MIL-C-17)

RG58 C/U QAXIAL – 50 Ohm coaxial cable (MIL-C-17)

The RG58 C/U QAXIAL cable is a 50 Ohm coaxial cable for general RF and radio frequency use, suitable for standard connections where ease of installation, adequate shielding and consistent performance are required. The construction and materials are designed for reliable operation in typical applications such as antenna connections, radio equipment, instruments and technical cabling. The product is compliant with the MIL-C-17 standard.

Main technical characteristics

• Center conductor: tinned copper 19 x 0.18 mm.
• Insulation: solid PE Ø 2.95 ± 0.10 mm.
• Outer jacket: black PVC Ø 4.95 mm, flexible and abrasion-resistant.
• Characteristic impedance: 50 ± 2 Ohm.
• Shielding: tinned copper braid with 95% coverage for EMI/RFI protection.
• Capacitance: 101 pF/m.
• Operating frequency: from DC up to 3 GHz (depending on application and cable length).

Typical applications

RG58 C/U is commonly used for standard RF connections and cabling where 50 Ohm compatibility and adequate shielding are required, without the need for ultra-low-loss coaxial cables.

• Available from stock: supplied by the meter with immediate availability.

FAQ – Frequently asked questions

Is RG58 suitable for antenna connections?
Yes. RG58 is one of the most commonly used coaxial cables for 50 Ohm antenna connections and radio systems, especially for short cable runs.

What is the difference between RG58 and RG58 C/U?
The C/U designation identifies a version with a tinned copper braided shield, widely used for standard RF cabling.

Up to what frequency can it be used?
RG58 C/U QAXIAL is specified from DC up to 3 GHz; performance and attenuation also depend on cable length and application.

Is it available by the meter and what is the maximum reel length?
Yes, the cable is supplied by the meter and is available from stock. The maximum continuous length per reel is 250 meters.
