Right on, Guy,

I use my Cushcraft 13B2 on my tower for 2m foxhunting and jammer tracking. 
High beams seem to be much more immune to multipath distortion than ground 
based portable/mobile beams. I have the rotor (Yaesu 800 SDX) lined up with 
true north (mid-day shadow method) and in triangulations in my county (with 
other stations), it has been right on every time.
I sweep the antenna from side-to-side and note the headings where the signal 
drops to the same strength on the meter, then calculate the heading exactly 
in between and plot it on the hunt map.
