I use a plumb bob and plumb line. When north star is first visible, I use these to determine true north on my horizon. I then create in my mind a picture of where that point is on the horizon. Then during daytime, I adjust antenna to point at that point on the horizon. A south-north road near my QTH is aligned with the same horizon point.
