Special coaxial cables

Advanced users often need non-standard coaxial cable types. Typical field of use for these coaxial cables is in various impedance transformers, internal wiring, combiners, couplers, splitters etc. They are typically hard to find since vendors often do not stock them. We are here offering you a few of these special coaxial cable types.
