The key element in the "quad" example was that the "quad" in question had 
multiple feedlines, which essentially eliminated it from the WPX 
definition of a tribander. As someone else pointed out, there are Yagi 
antennas that have multiple feedlines as well, and it is equally possible 
to design a quad which used a single feedline.

I disagree here. A V-beam has no more elements than an inverted V. A 
Rhombic has no more elements than a full-wave loop. The only difference 
is a matter of total length of the element (in wavelengths). 

For that matter, a single long-wire antenna would certainly fit in the S 
part of the TS category, but a long enough and high enough wire has 
significant gain over a dipole or vertical.

I don't think the rule needs to change -- as written, it is very concise. 
Perhaps it doesn't exclude all possible configuration that people feel 
need to be excluded (it also excludes some that perhaps should be 
included), but its still a pretty good rule as it stands.
