Antennas are simply, I mean let's face it, they are just a bunch of
metal and insulators!

However, they are very complex, this can be demonstrated with math or
Roy's excellent little visual aid, EZNEC.

I don't think you are a "smart ass" or "diabolically argumentative", you
are simply lost in this--as we ALL are.

It is a learning curve, some here help speed us along this curve, some
offer "other things." I know what you mean.

All antennas end up being a compromise of size, building ease,
materials, weight, wind resistance (wind loading), what neighbors will
tolerate in "artistic design", directional patterns, cost, etc., etc.

Really, there is no such thing as "the most efficient" antenna--least
not when you have to design an antenna for the real world. I think most
answers to your question(s) will seem vague to you, this is not because
of deliberate intent on those answering, it just goes to point out the
complexity of your most "simple questions" and the different
interpretations which can spring forth from even the most simple question.

Patience is a skill which benefits one in all pursuits one engages in...

Warmest regards,
