I'm glad to hear the CPA-19 gain was of benefit. That does not change my understanding of the purpose of an amplifier though. The job of any TV preamplifier or distribution amplifier is to overcome the losses in cable, splitters and poor tuner noise figure.
All amplifiers add some noise and distortion to the signal. All amplifiers have some maximum operating level, above which they fail to amplify and only distort.
Rule of thumb: One amplifier can be too many. Two amplifiers are almost always too many.
Having said that, if you want to experiment with the idea that an amplifier can be a substitute for an antenna, you're not likely to break anything trying. I sincerely believe your time and money would be better spent on antenna choice, placement and aim.
Wishing you much success.
