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.

SMA Connector

SMA (SubMiniature version A) is the most widely used RF connector in the industry, offering a threaded interface that provides a secure, low-reflection connection from DC to 18 GHz. Its compact size, 50-ohm impedance, and broad frequency range make it the default choice for WiFi equipment, software-defined radios, cellular antennas, GPS receivers, and RF test instruments.

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 SMA and UHF cable assembly is well suited for amateur radio, CB radio, and general-purpose RF patch cables. The combination of reliable SMA 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.
