<---Yes they are the same CONCEPT, but CATV ones would be 72 (75?) ohm. You, of course, need 50 ohm ones. The idea behind using them is to present an accurate 50 ohm load on the duplexer ports, because a change of load affects the tuning. If you don't have any, I'd suggest begging or borrowing some from a buddy :-) All I know is that the duplexers were set up as a Varinotch filter system. <---If I'm not mistaken, that's a notch type duplexer.
