[TowerTalk] RE: Compass question

[wi8w@arrl.net (WI8W)]

The technique I used for aligning my Yagi to north was to let my Garmin GPS
unit do the pointing.  It has a North arrow that is true north and not
swayed one bit by the magnetic field.  After mounting the antenna on the
mast, I put the GPS unit on the bearing plate of the tower, rotated the
antenna by hand until it aligned with that North pointing arrow and then
tightened the mast clamp bolts on the rotator. The alignment is "close
enough for government work."
