JS,

So you are saying that I have an Antenna and Transceiver
and can hear 5 Radio Operators in a Net on a Frequency;
but only 2 of them can hear me.

I then put a MatchBox in-line between my Antenna and
Transceiver and Adjust-It; and can still hear all 5 Radio
Operators on a Frequency and now all 5 of them can
hear me.

To Me That Is Very Real Improved Performance from
My Antenna and Transceiver that is a direct result of
using the MatchBox between them. ~ RHF
.

increase the capture area of a poor antenna, etc.

It will MASK that antennas' short-comings ... same as sweeping dirt
under a rug (notice, another mechanical analogy to the above.)

I guess, any possibly way it can be explained to you, will fail ...

If you introduce an inductance to resonate the antenna, you introduce a
loss, if you introduce a capacitance, the same ... LC or PI networks,
commonly used in matchboxes, have notable losses.

I have a 60ft longwire, mounted ~40 ft. in the air. Since it is only
physically resonate on but a couple/few freqs, and, since I am not
employing some form of matching on the antenna, and since the antenna
does not, naturally, present a correct impedance to my feedline/rig,
some form of lossy matching must be tolerated ... since the matchbox is
located at my receiver, whatever feedlines I choose will also become a
part of the "antenna." The ideal placement for a matchbox would be at
the antenna, as everyone is and has been aware of for a long time, or
should have been aware.

As I stated, continue to state, and have no other choice than to state
when worried about being correct--no matchbox will ever improve the
performance of a poor antenna--all it can do is allow you to get maximum
benefit of that poor performance.

You have separate components, affects/effects, terms, etc. all confused
and lumped together. Antenna design, capture area, etc. effect antenna
efficiency--the impedance that/those designs/constructions entail, and
the method of matching (transforming) that impedance to one acceptable,
is another "thing", all-together.
