LMR400 vs RG213 are two very good coaxial cables used for high-end radio frequency antennas. These two cables are very similar in size but there are several construction differences. The main difference is that the RG213 coaxial cable is the cheaper of the two and features a stranded bare copper center conductor. Whereas the LMR400 coax cable has a solid bare copper clad aluminum conductor. <\/p>\n\n\n\n
The RG213 coax also has a PVC jacket, which is different from the LMR400 coaxial cable that has a PE jacket. Now, these two outer jackets are interesting. PVC vs PE.<\/p>\n\n\n\n
Most household applications such as pipes, garden hoses, waterbeds, and vinyl raincoats, typically consist of polyvinyl chloride (PVC). While polyethylene on the other hand is used in bulletproof vests and a variety of other high-temperature products because of its strengths and versatility. So LMR400 uses polyethylene in the construction of its outer jacket which wins for cable protection.<\/p>\n\n\n\n
The shielding conductor of these cables is another significant difference that sets LMR400 vs RG213 coaxial cables apart. The RG213 has a single bare copper braid shield, whereas the LMR400 has a double shield which is made of an aluminum braid for the 1st shield and then a braided tinned copper for the 2nd shield. Winner LMR400 again.<\/p>\n\n\n\n
