1.37mm Coaxial Cable

1.37mm RF coaxial cable manufacturer, 1.37mm coax cable specification, Custom 1.37mm RF cable assembly, Lower loss thin coaxial cable

1.37mm coax cable has same size conductor as 1.48mm and RG178 cable, but smaller overall diameter which has similar cable loss but more flexible in limited spaced. It’s commonly terminated with Hirose U.FL-LP-088, and IPEX 20351-112R-37 to be RF pigtail for wireless communication systems, GSM system and GPS system.
