RF cable assembly interfaces include: BNC, SMA, TNC, F-type, RCA, SMB, MCX, MC card, N-type, etc. Tiankele offers coaxial RF connectors and tools such as cable strippers, coaxial crimping tools, compression tools and needle crimping tools to meet all your coaxial termination requirements.
Coaxial is a term derived from cable construction, as shown here. In a coaxial cable, an electrical pulse signal is transmitted along the length of the cable between the center conductor and the outer conductor. The center conductor and the outer conductor share the same centerline or axis, so the term is coaxial.
Shielding effectiveness is the relative ability to shield against bad interference. In coaxial cables, the outer conductor provides shielding to prevent interference signals from entering and to prevent signal leakage, thereby becoming an undesirable disturbance to nearby equipment. Shielding performance is measured in dB, with higher values indicating better shielding performance. The table below shows the relative shielding characteristics of the various shielding types.
Please note that as the shielding density increases, the shielding effectiveness value will increase. Due to the solid tube structure of the outer sheath, an optimum shielding effectiveness value can be found in a rigid coaxial cable. In this type of cable, the limiting factor of the shielding effect is the quality of the connector attachment.
