[Amps] Tuner Loss

[Paul Christensen]

> All tuners have losses. Losses create heat. You can't change physics.

But you can do a reasonably good job of avoiding the problems associated 
with physics if the underlying physics is understood.  All tuners have loss. 
Some designs have less loss than others.  A well-built ATU that can 
accommodate 1KW of power across a generous range of load impedances does not 
require a cooling fan.  If an ATU product uses a cooling fan, it's time to 
start asking tough questions of the manufacturer.
