The multipath problems are defeated with the 5th generation LG tuner. Other tuners (4th gen LG, and those made by other manufacturers) have minimal multipath reduction. These tuners were 'okay' in situations where the 'ghost' signal is weaker and/or arrives after the main signal. The benefit of the 5th gen tuner is that it adapts for ghost signals that are stronger and/or that arrive before the main signal.
(Imagine a situation where your window faces the opposite direction of the broadcast tower. The signal bounces off a nearby building/hill, through the window, and hits the antenna. This signal ends up being stronger than the signal that is travelling through your house (a straight line from the tower.)) The LG tuner really excels in this type of multipath situation.
