At one time I was really hot after getting some triaxial connectors, to use with an Austron 5 MHz distribution amplifier. Well, as with most of my projects, I managed to buy a whole bunch of connectors (found some on ebay and a bunch at a hamfest) and, as usual, never did anything with them. So, if you still need a triaxial connector I am sure I can help you out. 73 - Mike

This connector is for double shielded separate isolated or twinax sym. cable as used for very low voltage signals (thus avoiding unwanted gnd loops). The inner coaxial connector is in fact of lower diameter, but the outside shell has the same size as the std. BNC, but instead having 3 guide pins/slots. Trompeter is one manufacturer, unfortunately I have to dig to find my spare connector in the bag with the manuf. type no on. HP does have a cable for RF-equipment Model 11172B with male on both sides. I add some pictures showing plug and connector. I hope it can help clarifying a bit.
