75ohm RF Terminator w/DC Blocking

The experts say that you should terminate (or "cap") unused RF outputs. For MATV/CATV (Antenna and Cable TV) signals, that requires a simple 75 ohm terminator, which is nothing more than a 75 ohm resistor in an "F" connector cap.

But what if there is a DC component on the cable, such as an infrared repeater system or a power supply for an upstream component like a line amplifier at the antenna? A standard terminator would short out the power, keep things from working, and possibly damage equipment. But these 75 ohm DC Blocking terminators will terminate the RF signal without shorting the DC part of it. So now you can properly terminate all your RF signals, even satellite systems.

Note that you can always use this kind of terminator wherever you would use a regular terminator, but not the other way around.
