I used to have an antenna install shop way back in the day. Not an expert, but I know this to be true...
Antenna boosters (amplifiers) don't do anything to the quality of the original signal received. The signal quality is 100% dependent on the antenna and the reception it provides. It's based on gain and direction. What the antenna sees is a snapshot of the best possible picture you can get. What you do with that signal after the antenna does matter, so boosters will help with long runs of cable and splits. Each split is a halving of power, plus a bit more loss. The booster must be very near the antenna, otherwise you will boost the noise acquired from the cabling too. Preferably the booster is connected directly to the antenna poles. So if you have a roof antenna connected directly to a TV with a single unsplit run, and under 100 ft of RG-6, a booster is snake oil. Too much boost can damage the RF amplifier inside the TV.
Oh yea, a great old western for sure.
