Don't just take my word for it. Go look up VSWR and read just a few
paragraphs on the subject. You work in electronics, this is important
for you to understand.

Search for the term index of refraction for similar concepts in physics
for lightwaves, which are EM waves. Then you will get the idea behind
refraction of radio waves in the upper atmosphere. Short wave radio can
teach you a lot.


One condition is closer to a short circuit. That's all I know.

I always match impedance for maximum power transfer. I voltage match as
well, when power is not so important, e.g. signal sampling.

In practical usage, "receive only" is closer to sampling.

I know enough about electronics to keep my sorry ass employed.
