Engineers and proficient technical people live in a world of measurement,
optimization, and facts. Lots of things "work." Someone may use an antenna
with an unmatched 3:1 swr and get to the DXCC Honor Roll. I'm sure it has
happened.
But questions are posed and, hopefully, answered factually. Anecdotally,
there is the story of the ham who WAS on a light bulb. Yes, it worked, but
it was far from an optimal solution, I think we can all agree. With
tenacity, I'm sure someone could work all states on 20m or any
other band with a transmitter connected to a marine band antenna, but it
would be far from optimum.
As an engineer, I cringe when these anecdotes are told in context of an
answer to a technical question. They're entertaining, but not factually
helpful.
The problem is that the uninitiated user might not know the difference
between good advice and an entertaining anecdote.
If you really want to work 2m optimally, an antenna made for a frequency
12% away isn't the right choice, unless it is vastly less hassle to deploy
and use. Then, it might work, but it could be 50% as efficient, again
depending upon a number of factors as not yet discussed here.
