Indeed, SWR Boy. Let's revisit your original post, recorded on Google
as Message-ID: <8C71YHSI37921.3957175926@anonymous.poster>. In it you said:
"If you use the formula correctly, which maybe those coke-bottle
bottomed glasses prohibits you from doing so, you wouldn't make a
complete ass of yourself. But from reading your posts, I suppose you
just can't help yourself.
"Here's an example of using that formula, you gutless chickenshit.
"Here's the formula, so you can write it down when you sober up:
"LOSS dB -10 log ((SWR-1)/(SWR+1))
"Let's say the SWR is 3:1 and figure the loss:
"-10 log ((3-1)/(3+1))= approximately 3dB loss"
You clearly believed the formula was always correct, and then posted
what was supposed to be proof by its author. Unfortunately for you,
the author explicitly stated that it applies only to the special cases
of a shorted or open termination.
To quote from your own post, Mr. Wheeler stated:
"Terminating a perfect, lossless transmission line with an open or short
will result in an infinite SWR at the input end because all of the
reflected signal makes it back to the signal source. However, real lines
have loss, and this causes the reflected signal to weaken as it moves
back towards the signal source, hence the fall in SWR as one gets
farther from the load.
"The only problem one might have in employing the technique is that some
reflectance gear (like the MFJ) might not like certain impedance
combinations on a line (as you move down the line, there will be points
where the impedance is purely real, capacitive, inductive, etc), and at
certain positions the gear may not be able to deliver an accurate or
consistent reading.
"I hope this explanation helps. I left out the mathematical discussion
from the book since it is not really appropriate there.
73,
Tom Wheeler"
Do you see the part about terminating a transmission line with an open or
short circuit?
DO YOU SEE THAT????
It means that the formula you gave only works for a special case. It
means that you screwed up.
Your inability to factually recall your own posts could be a sign of
incipient mental illness.
Get help.
