Messi & Paoloni RG-58 is a flexible 50 ohm coaxial cable suited to short feed-line runs, patch leads and installations where compact size and easy routing are more important than the lower loss offered by larger coaxial cables.

The cable uses a 19-strand tinned copper centre conductor together with a solid polyethylene dielectric and a 92% coverage tinned copper braid.

At only 5mm overall diameter, RG-58 is easy to route around radio equipment, through vehicles and in portable installations. For longer runs or operation at higher VHF and UHF frequencies, one of the larger low-loss M&P cables will generally be the better choice.

5mm Diameter

Compact cable size for short runs, patch leads and installations where space is limited.

50 Ohm

Standard 50 ohm impedance for amateur radio and other RF applications.

92% Braid Coverage

112-wire tinned copper braid provides the cable screening.

Flexible Construction

19-strand centre conductor makes the cable practical for portable and equipment interconnection use.

Where RG-58 Works Best

RG-58 remains a useful choice where cable runs are relatively short and the convenience of a small, flexible cable outweighs the need for the lowest possible attenuation.

Patch Leads

Ideal for connecting transceivers, antenna switches, SWR meters and other 50 ohm equipment around the shack.

Short HF Runs

A cost-effective option where only a relatively short length of coax is required.

Mobile and Portable

Compact 5mm construction makes the cable easy to route and transport.

Attenuation

Like all coaxial cable, loss increases with frequency and cable length. RG-58 is best used where runs can be kept reasonably short, particularly when operating on VHF and UHF.
