Application
Coaxial cable for radio- and computer systems as well as the entire field of commercial radio-frequency
technology and electronics for low range transmissions, and with the small cable diameter, for application in
narrow spaces. Cable design and electrical properties of RG 188 A/U to MIL-C 17 F. Designation according to
MIL-C 17 F : M 17/138 – RG188.
The cable is intended for limited flexible use and for static laying. PTFE material is used to meet requirements
concerning low and high ambient temperatures resp. chemical stress.
