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-temperature applications and communication systems that require higher sequences and lower attenuation. It is also used in the transmission of data signals in applications such as LAN/WAN or GPS situations where high-temperature performance is needed.
