About This Assembly

RG58 Cable

RG-58 is a classic flexible 50-ohm coaxial cable with a 0.195" outer diameter, offering an excellent balance of flexibility and performance at a low cost. Its braided shield provides good EMI rejection and its thin profile makes it easy to route through tight spaces. Common applications include amateur radio, CB radio, networking equipment connections, and general-purpose RF jumpers up to 25 feet.

BNC Connector

BNC (Bayonet Neill–Concelman) is a quick-connect RF connector featuring a bayonet locking mechanism for fast mating and unmating, rated from DC to 4 GHz. Its ease of use makes it standard in test and measurement equipment, video distribution, two-way radio accessories, and laboratory bench setups where cables are frequently connected and disconnected.

Common Applications

This BNC cable assembly is well suited for amateur radio, CB radio, and general-purpose RF patch cables. The combination of reliable BNC connectors and custom-cut cable length makes it a practical choice for both field installations and bench setups. Every assembly is hand-terminated, continuity tested, and ships free within the USA.

Frequently Asked Questions

Is this cable hand-assembled in the USA?

Yes. Every CoaxRF cable assembly is hand-terminated and continuity tested at our US facility before shipping. We do not drop-ship pre-made cables from overseas — each cable is built to order.

Can I order a different length than 25 ft?

Yes. This page is for the 25 ft assembly. Use the length buttons above to select a different standard length, or use the Cable Builder for any custom length.

How much signal loss will I see with this 25 ft cable?

At 1800 MHz, RG58 loses approximately 21.5 dB per 100 ft. This 25 ft assembly will have roughly 5.38 dB of insertion loss at that frequency. See the signal loss table for all frequency points.

What is the maximum frequency for this assembly?

This assembly is rated DC – 1 GHz. The effective frequency limit is set by the lowest-rated component — either the cable or one of the connectors. Both BNC FEMALE and BNC MALE connectors must be within spec at your target frequency.

What is your return policy?
