List, I recently bout a couple of USB male to USB male cables from Newegg. About two weeks later I received a catalog from: Brake Manufacturing LLC. They make inter-connecting cables for almost any type of connector with almost any type of co-ax as well as selling almost any RF connector one can imagine. You can different types of connectors on the ends of each cable. Prices for a simple 3 foot cable start around $30. WWW.BRAKEMFG.COM Regards, Perrier
