Since most HF Yagi antennas have 3dB beamwidths on the order of 55-70
degrees, a few degrees of pointing error will have essentially zero
effect on signal strength. Don't spend too much time worrying about
whether you're precisely aligned with true North or not. You'll never
be able to tell the difference.
