There are no stupid questions.
Unfortunately, the answer is "maybe".
In general, though, if you had previously scanned in all 13 local stations earlier today, then you probably won't need to rescan again, just reposition your antenna until you get good reception.
However, if some of the local stations you are trying to get have never been scanned in, then yes, you need to do a rescan.
And if any stations have changed parameters (usually just boradcast frequency, but aometimes other parameters), you'll need to dleete them and rescan.
