Q: What is the difference between an amplifier and an attenuator?

A: An amplifier and an attenuator are exact opposites of each other. An amplifier makes the signal stronger in your network while an attenuator makes the signal weaker in a network when it is too strong.

Q: When would I use an attenuator?

A: You would use an attenuator when the power level is too strong in your network. If you exceed the maximum input power level you can damage your equipment. You might use one of these when you need a lower signal level for an antenna input on a sensitive radio receiver.

Q: When would I want to block DC power?

A: Many devices aren't designed to take in DC power so you would want to use a DC power blocking attenuator to make sure that your equipment doesn't get fried. They stop the DC voltage from getting through thus protecting your antennas TVs amplifiers etc.

Q: Can I get 26 dB of attenuation by cascading a 20 dB and a 6 dB attenuator?

A: Yes you can. Attenuators are additive so 20 dB + 6 dB = 26 dB.
