Jon ... to correct the record the A4S is a three element yagi 
on 10 meters.  The trapped reflector is active on 20/15 and 
the single reflector is active on 10 meters.  

With the A4, the longer boom provides higher gain and wider 
bandwidth on 15/20 but performance would fall off on 10 so a 
separate reflector was used to provide a better match and 
improved F/R on 10.
