Gregg, one point I would make is to never trust the wiring provided by the 
antenna OEM.  Years ago I put up a 4 yagi EME array using CC antennas and 
ASSumed that they wired every antenna the same way.  After realizing some 
poor performance and taking off the lids to the protective covers on the 
matching networks for each antenna I saw one of them was 180 degrees out of 
phase.  Always double check every wire starting at the driven element.
