The other thing about interference in our "world" is that we're dealing with digital signals, which is quite a bit different from analog in that it's much more of an 'on/off' situation. Yes, with interference, you get pixelation as the signal degrades past a certain point, but until then, you get a solid image. It doesn't vary from day to day. As long as you're above the magic signal quality level, it's always the same quality in terms of signal reception. It's either there, or it's not.
