In my 100m of W551 with a 16+j0 load at 30MHz, the loss in one metre

4.3% is nearer 1% of tx output.


What the heck is one "metre"? Netscape says that is misspelled and
probably should be corrected to "metro". Why aren't you guys on
the English system?

If the loss in each meter is 4%, wouldn't the loss in 100 meters
be 400%? What am I missing?

C'mon Cecil, you know it's an exponential decay.

I just started reading this thread. Is the loss in a 'per meter' or 'per
wavelength'? In the olden days, we quoted loss as Nepers per
wavelength. When did it change to 'percent per meter'?
