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.
