As K0PP pointed out, the physics of electromagnetic radiation and the
radiators that create it have been known for many years. "New kids on
the block" may be antenna and transmission line modeling software,
various analyzers, antenna system tools like HFTA, and the like.
Ironically, these sometimes complicate an otherwise simple task ... poke
RF into a conductor ... and they may tell you way more than you really
need to know, adding to the "if it's not perfect to 4 decimal places, it
won't work" syndrome.
A 4-stack of 6 element yagi's or an array of multiple rhombics a la W6AM
is obviously going to propel you toward the Honor Role much faster than
an OCF wire in your attic. However, it is not *required* to make Q's
and to enjoy HF ham radio.
I had the opportunity to help a new General put up a vertical. He was
obsessing over getting it exactly 43 ft long and getting enough ground
radials, when 42 ft would work about as well as 44 ft, and one radial
will make a big difference over no radials and two will be better than
one, but not twice as better. I did finally convince him to just put it
up, he ran 2 on-ground radials with the intention of adding more, and
began using it. I don't believe he's added any radials yet. [:-)
ARRL has petitioned the FCC for expanded HF segments to encourage new
[and younger] Technicians to upgrade. I'm pretty sure results will be
disappointing unless it's accompanied by a robust campaign to teach them
it can be easy and inexpensive.

Yes it is amazing that many contacts can be made with a mediocre antenna.
Many hams haven't been exposed to a really good performance antenna system.
There is a big difference.
