From my limited understanding of an attenuator, it's supposed to reduce signal strength in instances of too strong signals. Will it reduce all incoming signals, or just the ones it deems too strong? My concern is that if it reduces all signals by the same amount, other channel signals I'm getting might become too weak to pickup. I'm also wondering how it will fix the multi-path problem since I'm guessing the problem occurs before the signal gets to the attenuator.
As far as replacing my antenna, I am willing to give up picking up KFTA in HD for uninterrupted KNWA picture and sound.
