Reliable reception starts with (and can end at) the antenna, it's selection and placement.

Amplifiers can not 'pull' signal from the antenna or the air. An amplifier is analogous to a pump. Placing a premium high volume/pressure pump in damp hole will not make the hole into a well that produces drinkable water. If mud is all that the pump is supplied with, expect mud at the tap. If the antenna is receiving a distorted or noisy signal, an amplifier will deliver a noisy distorted signal to the TV. The job of an amplifier is to overcome the losses in cable and splitters on the output side of the amps, it can not repair or fix signal quality issues such as noise and distortion. With that said, the cost of a preamp may be such that you want to try it. If so, I'd suggest the RCA TVPRAMP1R or PA-18. The LNA-200 lacks adequate internal shielding which makes it unacceptable to ingress of signals that result in higher noise output in some applications.
