Discovering new principals is always in play, but that is very different from new configurations of metal. Even fractal antenna technology is based on all the base lines we know about RF.

What about a listing of truisms related to TB RX/TX antennas like:

An effective Marconi radiator does not need to be resonant to be 
efficient or for a  Marconi (vertical against ground) to work well it 
need not be resonant per se.

Nor does it need to be 90 degrees to work well as shorter length can be 
made to perform as well with proper planning and construction..

The gain of a yagi is not necessarily determined by the number of 
elements as much as by the length of the boom.

A TB vertical without radials performs better on the beach then it does 
inland on a  grassy hill.

I don't even know if the above statements are acceptable as they are 
just samples.  A peer review board comprised by the many antenna 
pundits, like Guy K2AV, that frequent this reflector could weight the 
results of basic TB antenna truths to save a lot of time and  bandwidth 
instead of haggling over them and getting down to the brass syntax.
