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.

N Connector

Type N is a threaded RF connector rated from DC to 18 GHz with a durable weatherproof design, making it the preferred interface for outdoor antenna installations, cellular base stations, and commercial wireless infrastructure. Its larger size compared to SMA allows higher power handling and the threaded coupling resists vibration, making it suitable for mobile and fixed outdoor applications.

UHF Connector

The UHF connector (also known as PL-259 male / SO-239 female) is a large, low-cost RF connector designed in the 1930s for HF and VHF frequencies. Despite its name, its practical usable range is below 300 MHz due to its non-constant impedance design. It remains extremely popular in amateur radio (HF through VHF), CB radio, and marine radio applications.

Common Applications

This N and UHF cable assembly is well suited for amateur radio, CB radio, and general-purpose RF patch cables. The combination of reliable N and UHF 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 50 ft?

Yes. This page is for the 50 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 50 ft cable?

At 1800 MHz, RG58 loses approximately 21.5 dB per 100 ft. This 50 ft assembly will have roughly 10.75 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 – 300 MHz. The effective frequency limit is set by the lowest-rated component — either the cable or one of the connectors. Both N MALE and SO239 UHF Female connectors must be within spec at your target frequency.

What is your return policy?

We accept returns within 30 days of delivery. Custom-length cables are accepted as long as they are in original condition. Contact us and we will provide a prepaid return label at no charge.
