There's talk about impedance and I have one question I've always
wanted an answer to, and I bet someone here knows it ...
I was at a convention and ended up in a lunchtime discussion about the
B-2 bomber. One person said, "The impedance across the wingspan is 133
ohms". Another nodded and said, "That's because that is the background
impedance of the universe."
To this day I don't understand this. Help?
[And I have been told in no uncertain times that the figure of 133
ohms is wrong.]
This relates to TC's in that, well, what is the impedance match from a
toroid out into the air? Does it help a coil to operate to attempt a match?
How on earth does one do that?
If you feel like responding directly to my mailbox, that's fine ...
