"Cecil Moore" says -

There's no such thing as a 100% efficient tuner.
====================================

Cecil, not a very surprising statement.
There's nothing which is 100% efficient.

What is the typical efficiency of a typical tuner with a typical
antenna.
Does it differ significantly from 100% ?
Yes or no?

I did some measurments on a MFJ tuner into a dummy load. While I am not
sure if the losses would be more or less than to an acutal antenna, I would
assume it should be the best case . The losses were around 5 to 10 watts
starting with 100 watts input depending on the band. I think 80 meters was
the worse from 80 to 10 meters. This is a small tumer rated around 200 or
300 watts and has a built in wattmeter. This may account for a small
aditional loss. I did not use this meter but did use 2 Bird meters , one on
the input and one on the output to keep the input power constant at 100
watts.
