RF Elements pigtail MMCX–MMCX coax signal cable, black with gold-plated contacts, model MMCX-MMCX-25

RF Elements pigtail MMCX–MMCX coax signal cable (model MMCX-MMCX-25) is a compact interconnect cable with MMCX male connectors at both ends, a black outer jacket and gold-plated contacts. Built on RG178U coax, this cable is intended for short RF connections where a low-profile, reliable contact is required between devices with MMCX ports, such as small antennas, radios, modems and test equipment. The slim construction and MMCX termination make it suitable for installations with limited space and where frequent mating and unmating may occur.

Advantages

The cable uses RG178U coaxial dielectric and a flexible black jacket to deliver stable RF transmission in a compact form factor. Gold-plated MMCX contacts offer improved corrosion resistance and consistent electrical contact. With identical MMCX male connectors on both ends, the cable provides a straightforward, low-profile connection between compatible ports without adapters. Its short length and flexible construction help reduce strain on ports and simplify routing in constrained enclosures.

Suitable for

• Connecting antennas to radios or modules with MMCX ports
• Interfacing modems, dongles or small wireless devices
• Laboratory and test setups requiring short RF jumpers
• Equipment racks and enclosures with limited clearance

Key specifications

• Cable type: RG178U coaxial
• Connector type (both ends): MMCX male
• Contact plating: gold-plated contacts for corrosion resistance
• Outer jacket color: black
• Design: low-profile, flexible pigtail for short RF connections

How to use

Align each MMCX male connector with the corresponding MMCX female port and press gently until a tactile click or secure fit is felt. Avoid excessive force or twisting when mating to prevent damage to connectors. Route the cable to minimize sharp bends and avoid kinking; maintain gentle bend radii appropriate for RG178U cable. For test or lab use, use the cable as a short jumper between devices, ensuring connectors remain clean and free of debris.

Usage recommendations

Inspect connectors periodically and clean contacts with a suitable contact cleaner if signal loss or intermittent contact is observed. Avoid exposure to prolonged moisture and mechanical stress; secure the cable to relieve strain on the MMCX ports. Choose this MMCX–MMCX pigtail when a short, low-profile RF connection is needed between devices that accept MMCX terminations.
