Remember modeling only tells you what your receiving antenna pattern may look 
like.  With the help of a GPS and portable reviver with an S meter, you can get 
a better idea of what the pattern really is.  First put your coordinates  of 
your receive antenna into the GPS, Feed a small amount of power into your 
receive antenna. (not enough to damage the matching transformer) Then 
drive/walk around your antenna with the portable receiver/Mobil rig and take 
readings. (more distant readings are much more accurate) With your GPS in the 
goto mode, and receive antenna coordinates you selected,  you can collect 
signal strength readings.  A modern GPS will give you the direction back to 
your QTH/receive antenna, and distance. Find the right roads/locations, to get 
your readings, and get busy. Try to take all the readings at the same 
distance/or interpolate. Take many different location readings to help weed out 
the error ones that come from signal obstructions.
