Those ranges of impedances are basically worthless.
I don't agree :-)
If I had to test such a tuner the first thing I would do
is put a pure resistor of those values and try to
match them accross the frequency and power range announced.
Measuring the insertion loss would be nice too.
Of course it is not the complete story but a good start.

Which basically tells you nothing about the ability to match a complex
load.
Hello
You are absolutely right in fact a perfect ferrite transformer would be
better.
But an aerial must have a real impedance part to be of any use :-)
Specifications must be easy to verify.
Here it is the case.
How do you check the 0.1dB noise figure advocated by many LNB's ?
