Service Tech for a cable company doesn't know what an attenuator is? Figures....

It's a passive device that reduces signal amplitude. If it's an RF attenuator, then it's designed for RF levels. They're usually labeled like -3db or -6db, even up to -20db. (Hey cable tech, what does passive mean?)

Passive means that there is no power being supplied, or no active components (such as diodes, transistors, or ICs)
If there's no power applied, how can there be any amplification? There can't.

I work in the CE manufacturing industry, we're constantly amazied at how little cable techs know. Don't even get me started on cable cards.

Flapjack and doughboy don`t have a clue !
IdiotWin is no idiot ! he is spot on !
However to reiterate an RF attenuator does not amplify anything ! it just reduces RF signal OK .

What Is An Attenuator

It is a device used to reduce the rf power comming into a piece of equipment. They can be fixed attenuation or variable. Sort of like a volume control for RF

Consider it a filter.....it basically amps the good signal and kills the extra "noise" All cable systems have a noise floor that varies in levels. What the attenuator does is amp "good" signal and block out things from the noise floor like interference from CB radio and other over the air broadcasting signals.

Actually it is designed to amplify wanted carrier signals and reject unwanted signal.
