Unless you have variations in the declination the |reading  should keep up.

My idea was to use the magnetic compass as a sensor, not as something  
absolute holy grail. Direct the antenna to the north (or to whatever direction  
suits you) and rotate the magnetic compass, hopefully mounted on  the 
rotating part of the antenna installation until it shows north (or  whatever 
direction you are pointing the antenna) Yeah, you might live in an area  with a 
fast (!!) change in the declination, but then a magnetic compass is  useless 
regardless what you try to use it for. Maybe then a GPS could be useful  
instead.I think that a magnetic compass would work for the rest, 99%  of us 
though. (I still recommend a north-seeking plastic owl if you have  problems 
finding true north:-)
