electro base connector set for coaxial cables — MCX, TNC, BNC, SMA compatible with RG8 RG178 RG316 RG174 LMR400

Set of electro base connectors for coaxial cable terminations compatible with MCX, TNC, BNC and SMA interfaces. This kit is intended for terminating and repairing coaxial assemblies using common cable types such as RG8, RG178, RG316, RG174 and LMR400. The connectors provide standard mechanical interfaces for radio frequency (RF) signal transfer and are suitable for use in telecom installations, test equipment setups and amateur radio cabling tasks where reliable electrical contact and correct impedance matching are required.

Advantages

The connector set offers a compact range of widely used RF connector types in a single kit, reducing the need to stock multiple separate parts. Each connector is manufactured to provide consistent mechanical fit and stable contact pressure, which helps maintain signal integrity. Compatibility with multiple cable diameters allows flexible use across different projects. The construction supports repeated assembly and disassembly for repairs and testing without significant degradation of performance.

Suitable for

• Field repairs of coaxial cables in telecom and network equipment
• Custom cable assemblies for test benches and measurement rigs
• Amateur radio antenna feedline terminations and modifications
• Prototyping and small-scale production of RF interconnects

Key specifications

• Connector types included: MCX, TNC, BNC, SMA
• Compatible cable models: RG8, RG178, RG316, RG174, LMR400
• Frequency range suitable for common RF applications (dependent on connector/cable pairing)
• Impedance: standard 50 Ω interfaces for TNC, BNC (when 50 Ω version), SMA and MCX
• Material: metal body with plated contact surfaces for corrosion resistance
• Mechanical retention: threaded and bayonet coupling as appropriate for each connector type

How to use

Prepare the coaxial cable by stripping the outer jacket, braid and dielectric to the dimensions required by the selected connector type. Slide any required ferrules, insulators or sleeves onto the cable before fitting the center contact. Solder or crimp the center conductor according to the connector's assembly method, then secure the braid and outer conductor with the ferrule or body. Assemble the connector body around the prepared cable, ensuring correct seating of the dielectric and contact. Verify continuity and correct polarity with an appropriate tester before putting the cable into service.

Usage recommendations

Use the connector type that matches the cable's outer diameter and the system impedance. When making assemblies for high-frequency or critical RF paths, follow the specific dimensional and soldering/crimping instructions for each connector type, and check return loss and insertion loss with a network analyzer if available. Store unused connectors in a dry, dust-free container to preserve contact surfaces.
