It's not supposed to but does have a tiny effect in practice.

I hate to be pedantic but how much? Are we looking at 3-4dB?

Less than 1dB. Usually closer to 0.1

It depends really, as it should reduce it by enough to notice it but if it is a faulty attenuator then it could do.

I saw plenty of them when I was doing installs.

Are you having a problem or are you just wondering?

I am completing an online course and this was one of the questions. Believe it or not the instructor did not know the answer. Thanks for the feedback!

Re: Does a forward path attenuator reduce return path

Just to correct slightly what I posted as I have just noticed a slight mistake with it.

It should read

"It depends really, as it shouldn't reduce it by enough to notice it but if it is a faulty attenuator then it could do."
