RF Coaxial Cables, Antenna Pigtails & Bulkhead Interfaces

RF coaxial cable assemblies for wireless antennas, WiFi, GPS, 4G / 5G, RFID, radio equipment, test systems, automotive RF interfaces, compact embedded modules, SDI video and equipment-panel connections. This collection includes SMA, RP-SMA, N-Type, TNC, BNC, FAKRA, MCX, MMCX, I-PEX / U.FL and MHF-series cable assemblies, antenna extensions, panel-mount bulkhead leads, RF feed-through couplers, MIMO antenna cables, low-profile window pass-through solutions and selected RF attenuators.

Choose by the complete RF path: operating application and frequency range, system impedance, connector family, standard or reverse-polarity format, connector gender, mating interface, cable type, cable length, panel-mount or bulkhead requirement, bend space and installation environment. A coax connector shell may look similar to another interface while still differing in center-contact arrangement, keying, impedance, thread, mating geometry or intended application.

Selection note: Do not select an RF cable by connector name or external appearance alone. SMA and RP-SMA use different center-contact conventions despite similar threaded shells; FAKRA connectors require the correct mechanical code and mating format; BNC systems can be specified for different impedances; and miniature I-PEX / U.FL / MHF interfaces must match the exact module-side connector generation. Confirm the complete end-to-end interface, impedance and application before ordering. A passive RF cable, coupler or adapter does not amplify a signal, create MIMO capability, convert a radio band, improve antenna gain or correct an impedance mismatch.

How to Select the Right RF Coaxial Cable Assembly

RF coaxial cable selection is an end-to-end signal-path check. This collection includes antenna extensions, embedded-module pigtails, panel-mount feed-throughs, automotive FAKRA cables, MIMO assemblies, BNC / SDI connections and passive RF adapters. A correct cable must match the actual connector interfaces, impedance, cable construction, signal application and mechanical installation requirements from one end of the RF path to the other.

Application	Typical RF Cable Role	Confirm Before Ordering
WiFi, GPS, LTE, 4G / 5G or embedded wireless module	Miniature RF pigtail linking a module-side I-PEX / U.FL / MHF interface to an SMA, RP-SMA, MCX, MMCX or panel-mount antenna connection.	Exact module-side connector generation, antenna-side connector, standard or RP-SMA format, system impedance, cable route, bend space, cable length and panel requirement.
External antenna, radio, RFID or test-equipment extension	N-Type, TNC, SMA or BNC extension cable, bulkhead lead or panel feed-through between equipment and an external RF antenna or test interface.	Connector family and gender, intended impedance, required frequency band, cable-loss target, cable type, bulkhead mounting dimensions, sealing needs and outdoor / vibration conditions.
Automotive antenna or vehicle RF interface	FAKRA-to-SMA, FAKRA-to-I-PEX, FAKRA bulkhead or equipment-specific antenna cable assembly for a defined vehicle connection.	FAKRA mechanical code, connector gender, mating interface, cable orientation, specified impedance, module-side connector, cable length, vibration route and equipment reference.

Common RF Coaxial Formats in This Collection

Antenna Extensions, Pigtails & Mixed-Interface Cables

Used to connect a device, module, antenna or radio interface through defined connector families such as SMA, RP-SMA, N-Type, TNC, MCX, MMCX or I-PEX. Confirm both ends, impedance, cable type and required length before selecting a standard or custom assembly.

Bulkhead, Panel-Mount & Feed-Through Interfaces

Used to bring an RF connection through an equipment enclosure, cabinet or antenna panel. Check the panel-hole diameter, thread or mounting hardware, panel thickness, front/rear connector format, cable exit path, sealing arrangement and actual mating connection.

FAKRA, MIMO, SDI & Passive RF Components

Used for vehicle RF interfaces, multi-antenna routing, high-density video connections, passive attenuators and defined connector conversions. These products must be selected by the system design, including code/key, impedance, frequency, port mapping, attenuation value or video interface—not just by the external connector shape.

Impedance and connector polarity are part of the RF specification. A cable may physically connect while still being unsuitable for the signal path. Confirm the intended system impedance, standard versus reverse-polarity connector format, FAKRA code where applicable, cable loss requirement and frequency range. For passive attenuators, also verify the required attenuation value, impedance, operating frequency and power requirement. Do not use a passive RF adapter as a substitute for active gain, filtering, conversion or antenna-system design.

Information Needed for a Custom RF Coaxial Cable

For a compatible custom RF cable assembly, provide as much of the following information as possible:

Equipment, antenna or module brand, model and application Original cable or connector part number, label or existing sample Clear photos of both mating faces, center contacts and connector sides Connector family, gender, standard or RP format and FAKRA code if applicable Specified impedance, operating frequency and intended signal application Cable type, desired length, flexibility and acceptable loss requirement Bulkhead or panel drawing, mounting hole, panel thickness and sealing need MIMO port count / mapping, attenuation value or test requirement where applicable

FAQ

What should I check before ordering an RF coaxial cable?

Confirm the application, connector type and gender at both ends, system impedance, required frequency range, cable length, cable type, connector orientation and any panel-mount or environmental requirement. Photos of both mating faces are especially useful for SMA, RP-SMA, FAKRA and miniature I-PEX interfaces.

What is the difference between SMA and RP-SMA?

They use similar threaded outer shells but different center-contact conventions. A standard SMA connector and an RP-SMA connector should not be assumed to mate correctly or provide the intended RF connection without checking the center pin and socket arrangement.

Can I use a 50-ohm cable in a 75-ohm system?

Do not treat this as a general substitution. The intended impedance should match the system specification because impedance mismatch can affect signal behavior and performance. Confirm the equipment, cable and connector requirements before selecting a replacement.

Does a longer RF coax cable reduce signal strength?

Cable loss depends on the cable construction, operating frequency and total length. Choose the cable type and length for the actual RF path rather than extending a connection with an unspecified cable.

Can a passive RF adapter increase antenna gain or create a MIMO connection?

No. A passive cable, coupler or connector adapter only routes a defined RF path. It does not add gain, create extra antenna paths, convert a radio system or replace the required antenna and radio hardware.

How do I request a compatibility review or custom RF coaxial cable?

Send the equipment details, original cable or connector reference, photos, required connector ends, system impedance, operating application, desired length, panel dimensions and installation information. Contact us for a compatibility review.
