What is RG188 Coax Cable?

RG188 Coaxial Cable is a 50-ohm coax cable ideal for use in a variety of applications, including direct burial applications. This cable features a silver-covered copper-clad steel inner conductor, solid PTFE dielectric, and a white Type VIIA PTFE jacket as specified by MIL-C-17. It has a wide temperature range of -55°C to 250°C, making it suitable for high temperature applications and communication systems that require higher sequences and lower attenuation. RG188 is also suitable for LAN/WAN, GPS, and antenna signal transmission applications where high-temperature performance is needed. RG188 also has a silver-coated copper shield in order to prevent electrical interference, guaranteeing an excellent and consistent current.
