RE: How do you.....

It ain't so! The scan just presets the channels that are strong enough for the TV to display and only has to be done once, although you might want to scan once a year to see if any new channels are available. If the stations in the other two directions are not strong enough they will not be picked up during the initial scan. I believe (not sure though) if you reposition the antenna and scan again you will lose all your previous presets so it would be better to scan the direction where the most channels are available and then reposition and manually add/edit the additional channels. Once the channels are preset you do not have to rescan or re-add them even when changing position.

"I've done scans and moved the antenna back to a previous direction and manually entered a channel number that worked in that direction but no go."

Even if you wiped out the previous presets if you manually enter a valid channel it should still work. You may have entered the channel number of the station instead of the actual channel it was broadcasting on.

As for tuner quality it's not like an FM tuner for longer distances. They are not the weak link for local broadcasts. If you are not receiving a broadcasted channel it will almost always be because of the signal strength, interference, antenna or antenna position.
