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.

FME Connector

FME (For Mobile Equipment) is a miniature threaded RF connector designed for mobile and vehicle-mounted antenna applications, particularly at GSM, CDMA, and FM frequencies. Its small size and robust threaded coupling make it common on vehicle-mount antenna mounts, cellular signal boosters, and mobile broadband modems.

MCX Connector

MCX (Micro Coaxial) is a snap-on RF connector approximately 30% smaller than SMB, designed for compact equipment requiring frequent connections in a small footprint. Rated to 6 GHz, MCX is commonly used in GPS receivers, automotive telematics modules, handheld communication devices, and compact measurement instruments.

Common Applications

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

What is RG58 coaxial cable used for?

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.

What is the signal loss of RG58?

At 1800 MHz, RG58 has approximately 21.5 dB of loss per 100 ft (0.215 dB/ft).

What frequency range does this assembly support?

This assembly is rated DC – 1 GHz, limited by the lowest-rated component across the cable and connectors.

What is a FME connector?

FME (For Mobile Equipment) is a miniature threaded RF connector designed for mobile and vehicle-mounted antenna applications, particularly at GSM, CDMA, and FM frequencies. Its small size and robust threaded coupling make it common on vehicle-mount antenna mounts, cellular signal boosters, and mobile broadband modems.
