What's more, the Model 460RC and 465RC are modular, meaning that each balun can be added or replaced separately. Purchase an entire panel fully populated with 16 balun modules (Model 460RC/16/F or 465RC/16/F). Or purchase the chassis separately (Model 460R/16 or 465R/16) and add balun modules (Model 460RC/F or 465RC/F) as you need them! On individual twisted pair ports, shield-to-pin and shield-to-ground connections are strap selectable. So you are not locked into the same configuration for every balun in the panel. If you need to do multiple 75 ohm to 120 ohm conversions, the Model 460RC and 465RC are definitely the way to go!
