We will see these common signs in the coaxial cable, in addition to RG, there will also be SRF, SYV and so on, which mainly represent the model classification of each country or different company of the coaxial cable.
Use RG178 coaxial cable, SMA male connector to SMA male connector
RG series: take RG-178 as an example, RG is the general name of coaxial RF cable in American military standard MIL-C-17, while 178 is just serial number. different numbers represent different cable material, characteristic impedance, electrical and mechanical performance requirements, etc., covering a wide range.
SRF series: SRF series of low-loss physically foamed coaxial cable manufactured according to LMR standard of American TIMES company, general wire named SRF-LMR-100 and so on.
SYV series: according to the coaxial RF cable series in the national standard GB14864 or line standard SJ1132-77, taking SYV-75-2-1 as an example, SYV is the general name of the type of coaxial radio frequency cable in the national standard GB14864 and line standard SJ1132-77, and the insulation medium is PE. In SYV, S stands for coaxial radio frequency cable, Y for polyethylene, and V for polyvinyl chloride.
"75" stands for resistance, the latter 2 represents its insulation outer diameter (about 2mm), and the last 1 represents the conductor specification: "- 1" represents the conductor structure serial number as a single strand, and "- 2" represents a conductor structure serial number as multiple strands.
We know that coaxial lines are generally divided into 50 ohms and 75 ohms according to impedance, so the serial number after RG will be different.
75-euro coaxial lines are commonly used in video transmission systems such as cable TV, such as RG-179, RG-59.
The coaxial line can also be divided into flexible cable and semi-rigid cable according to softness and hardness.
semi-rigid cable: for example, RG-401, SFT-50-2-1, etc.
