The tradeoff from this is that it also filters out some of the signal.

Not really, attenuation in the freq actually used by the services is very controlled with all other freq getting negligable attenuation.
They do not filter out noise afaik they are there to control slope/tilt, simulate extra cable length to balance signal and lower signal by a set db. Somewhere if you search for attenuator you'll come across a full post on dot com explaining this in full.
[edit]look at the last post in this thread
