You're right, if your antenna is not receiving a clean signal, an amplifier is not going to filter out the noise and interference... both are amplified right along with any desired signal. An amplifier is only intended to overcome loss in cable and splitters connected to the output of the amp. No amplifier 'pulls' signal in. Amplifiers are only capable of 'pushing' signal out. Unless you are going to drive some unusually long runs and split many ways, I see no need for amplification. There's plenty of signal power in the air according to the report you've posted.
Follow timgr's suggestions. Be open to adjusting aim and mounting height as well as location. While you're up there, carefully inspect the antenna, coax and connectors for signs of weathering, corrosion or other damage. Any moisture allowed to enter the coax will make it unreliable. Wet coax can affect just one channel if the conditions are just right. If water intrusion is suspected, a new cable and connectors are needed. Wet cable can never be trusted, and should be scrapped rather than salvaged.
