Why Antenna Tuners Aren't Necessarily Useful for Shortwave Listening

The same argument could be used to say, "Why 9-to-1 Baluns Aren't
Necessarily Useful for Shortwave Listening."

If one is a true RF professional the idea of putting a Hi Z generator
into a Low Z load is too much. The 9:1 autotransormer also puts every
part of the antenna at DC ground, thus protecting the radio's input.
Plus, it's a very elegant way to connect the wire to the shielded
cable.

Still, you have that wonderfully sensitive receiver, and your balun
hasn't changed the signal to noise ratio; it's only made everthing
louder. Same argument he's using against antenna tuners :-)
