What is RG188?

The RG188 Coax Cable is a 50 ohm coaxial cable used in a variety of applications including direct burial applications. Due to its high temperature range, RG-188a can be used for high tempertaure applications and communication systems that require higher sequences and lower attenuation. It is also used in the transmission of data dignals in applications such as LAN/WAN or GPS situations where high temperature performance is needed.
