Can't have it both ways. A resistive pad will match the impedance at the cost of insertion loss. This may not matter depending on the circumstances. If you are evaluating the performance of one antenna vs another, etc, then just realize that you are burning up power in the matching pad. If you...

That is likely just a resistive pad to eliminate reflections on transmission lines. It is certainly not lossless or even close. My guess is 5.7 db of insertion loss.

This makes sense to me.

I gave my layperson's opinion with the lame analogy with the rubber tape measure. I am implying that you cannot change the speed of light without changing spacetime and matter (if that were even possible ) in such a way as to make our measuring tools come back and give us the same number we had...

I can watch two cheetahs running and watch one approach and then pass the other, knowing which one is moving faster without knowing or caring about units or dimensions.

This is like asking why pi is 3.1415..... - It's easy for us mere layperson's to wrap our heads around that, kind of.... - I think a better approach is to ask what the universe might be like if C were different than it is. Just how far into the fabric of spacetime, matter, etc the speed of light...

You can chuck it into a drill and turn it while against the grind stone. Thread a nut on to improve the grip.

What's wrong with either? You know sooner or later kids will climb in. It's a kid's nature to use things in manner not intended.

Maybe it's just me but I noticed 35 years ago the ARRL publications were a bit 'scattered' concerning skill level. In the same book they will describe something in very beginner's terms but the next chapter a different subject is way over the heads of many readers. Multiple books with...

Have you actually read this entire thread?

Of course complex sounds contain multiples. What's the point?

This doesn't need to go very deep to explain that the phase relationship between two signals of different frequencies will never cause cancellation no matter how hard you try. - Here's a little advice for you: When something does not make sense to you and contradicts mainstream accepted science...

It opposes a changing current. Inductors are happy continuing to pass a non-changing current. Try to increase it or decrease it and it does what it has to in order to counter this.

The simple answer is you are misapplying what you've been taught.

The development of many things we have today was driven by the fact that what existed prior was not cost effective for the general public. - If Union Pacific wants to look into this I'm betting they have better qualifications to justify that move than you or I.
