Its incorrect to state that amplifiers arent useful in antennas systems for anything other than overcoming transmission line loses, splitter, and other gizmos which introduce loses.
Yes, most of the time if they are a modern low noise amp, the lower the noise floor of the system.

I didn't say they weren't useful or I would not have added the facts about noise where the real improvement comes from using an amp.

What ever.............

nah, its a pet peeve of mine not to blur the real reception improvement most often seen from an amp on a short coax run is lowering the noise and not the gain.

To me anything that blurs the difference in noise floor and gain breaks one of my cardinal rules of antenna system analysis.
