True, but it still beats using a full band antenna which can have some
funny patterns at a few channels. Sure, a single channel yagi at channel
30 might well be usable from 24 to 36. Buy the antenna for the channel
you want (or at least very close to it) and you get a clean and narrow
pattern.

This is a good source for preamps.
