[Elecraft] Mathematically challenged

Yes. The family of beam antennas also includes in addition to antennas using 
parasitic elements such as the Yagi,  arrays of two or more driven phased 
elements,  one or more radiating elements in front of  a plane reflector, a 
termninated rhombic, a helix and many other types. . IIRC sometime in the 
dim past many hams started to call yagis  'beams', which they are, but all 
other types of antenna system which also exhibit unidirectional patterns and 
are 'beams' by other names. I don't know why the Yagi, which is just a 
member of  the 'beam' family of antennas, received this preferential 
treatment.
