Default tuner - feedline - antenna question ?

In the theological sense, this predicates that power never becomes
dissociated from "the source." That is ambiguous, isn't it?

Is that to include the batteries behind the collector supply? The
power supply charging the batteries? The power grid feeding the power
supply? The generator driving the grid? The Coal firing the steam
spinning the generator? The sun through photosynthesis growing plants
to provide the coal? The previous supernova that seeded the cosmos by
which coalescence formed the sun? ...and into an infinite regression
to that previous supernova?

The energy dissipated is computed from the Galactic Load Line.


Sarcasm clearly noted, and surprisingly uncalled for. I'll try asking
one more time. It is a simple metrology question: How were you able
to directly ascertain that the heat being dissipated in the source was
produced by energy being reflected from the load?

Thanks,

Jim, AC6XG

Hi Jim,

I responded in kind is all, you revealed a trap and I jumped into it
with both feet. If that broke it, return it to the vendor for a
refund.

Is power/energy separable from its source? If this question is
obnoxious, why did you raise the prospect?

When it is generally accepted that our sources do not exhibit 50 Ohms
source resistance/impedance, what resistance/impedance do they
exhibit? If you don't have an answer, what was the purpose of this
uninforming assertion?

If these two questions have the trappings of sacrasm, I did not
originate their discussion. And putting your mock-shock aside, they
are part of the chain of denial you are adding links to, aren't they?

What other point is there to attaching an antenna to a transmitter?

Hi Jim,

I will take that as an affirmative.

When it is generally accepted that our sources do not exhibit 50 Ohms
source resistance/impedance, what resistance/impedance do they
exhibit?

It doesn't matter. The net power supplied by the source
is *always* the difference between the forward power
and the incident reflected power *by definition*.

The definition seems to assume that 100% of the
incident reflected power is re-reflected *as if*
a 100% re-reflection condition exists.

To which I got no answers in stereo.

Some may sense frustration to which I once asked how much relief I
would need. Having already long anticipated a non-response (score
100% for accuracy in modeling); others may want to fumble rhetorically
with equally uninformed responses. In anticipation of that I provide
a multiple choice. Richard needs to take:
1. An aspirin;
2. A syringe of morphine;
3. Both of the above;
4. 50 Ohms of dissipation.
5. All of the above, except 3.
6. ____________

Now take that number, and divide it by the Sarcasm co-efficient.

Plot this on a graph and draw an asymptote. You now have a diagram
for a Gaussian Bundle. Find the Pointing Vector for this (it points
to the same answer you picked in the multiple choice) to verify the
authenticity of your newsreader's software design. ;-)
