I'm satisfied with a mast too. A shingled attic will take out about 30%
of reception. Why do anything to a maximum of 70% efficiency?

If the signal is strong enough, 70% will give you a picture EXACTLY like
100% will. An attic installation may be preferable in other ways.

Come to think of it, that's the advantage of digital, if the signal is
strong enough. Since the value can only be 0 or 1, whichever it's
closer to (or whatever other standard is used) it will be interpreted as
a 0 or 1. I'm sure it's smart enough that, if the signal is at 70%,
it doesn't just call everything below 50% zero and everything between 50
and 70 one. Instead it would note the maximum signal strength of 70,
and call everything 35 or above 1, and everything below 35 zero. (or
use a method parallel to whatever method or standard is used with
stronger signals. )
