RG56 manufacturers tell you that coaxial cable is a broadband transmission line with low loss and high isolation. A coaxial cable consists of two concentric cylindrical conductors separated by a dielectric spacer. RG56 manufacturers tell you that the capacitance and inductance distributed along the coaxial line will produce distributed impedance throughout the structure, that is, characteristic impedance.

Resistive losses distributed along a coaxial cable make losses and behavior along the line predictable. RG56 manufacturers tell you that under the combined effect of these factors, coaxial cables transmit electromagnetic (EM) energy with much less loss and less interference than antennas under free-space propagation conditions.
RG56 manufacturers tell you that coaxial cable products have an external conductive shielding layer, and other material layers can be used on the outside of the coaxial cable to improve environmental performance, EM shielding capability and flexibility. RG56 manufacturers tell you that coaxial cable can be made from braided conductor strands, which, combined with clever layering, make the cable highly flexible and reconfigurable, light and durable. RG56 manufacturers tell you that as long as the cylindrical conductor of the coaxial cable maintains concentricity, bending and flexing will have little effect on the performance of the cable. Therefore, coaxial cables are typically connected to coaxial connectors using a screw-type mechanism. Use a torque wrench for tightness control.
