[TowerTalk] Declination Question (True North)

[john at kk9a.com]

I'm doing some antenna work in Aruba and I would like to properly align my 
antenna north using a compass, not by staring into the Sun or some other 
star, etc.  If I calculated this properly the declination for this country 
is -9 degrees, 40 minutes.  I think this means that when I point my compass 
north, I am really looking -9 degrees, 40 minutes.  So, if I set my rotator 
to 350 degrees and then aim my antennas north using my compass, will my 
antennas be aimed at true north when I turn the rotator to 0 degrees?  I 
don't want to compensate incorrectly and be off 20 degrees.
