RG214's dual braid shielding minimises interference and signal leakage, making it suited to high performance RF systems across a wide frequency range, commonly in commercial, broadcast and industrial environments.
RG214 adds a second braid shield over RG213's single braid, giving better protection against interference and signal leakage in demanding RF environments. If that extra shielding isn't needed for your application, RG213 is the more standard option.
