Yes, it's still RF. But my main point was that if he's trying to
improve an analog signal, it may not be worth the trouble as it's
going to be gone in a year. I'd be figuring out how to transition to
ATSC first, as that may solve his problem. The reception conditions
he has for digital may be different.

Amplifiers and antennas are not smart enough to distinguish between
analog and digital signals.

You miss the point. In a year the analog will be gone and with ATSC
his reception right now may be fine WITHOUT needing an AMP. Anyone
screwing around with improving NTSC reception should take that into
account.
