Currently, Ronja is using wire nuts. We haven't yet noticed a failure tracked down to a wire nut and they are mechanically rugged. Also they seem to perform fairly well up to say 300MHz (when the incoming and outgoing cables are impedance-matched coaxials) according to edge observations on oscilloscope. The disadvantages are labour-intensive assembly and disassembly, large size and accessibility of the contact with a tool or stray bare wire. http://images.twibright.com/images/ronja/pc_interface/brain&johanka/aui_johanka0.png The cable ends arming technology seems to be finally reliable against break-off during manipulation after some development (ignore the eyelet): http://images.twibright.com/tns/117c.html http://ronja.twibright.com/cabling/building.php Cl< > > These people make really good products.
