Palstar AT-4K - High Power Tuner
The American manufactured Palstar AT4K is an impedance matching network that fills the void for
a matching network that can provide unbalanced/balanced output.
This is a
one-of-a-kind unique dual-function high-power tuner in the American Ham tradition.The typical unbalanced tuner with a 4:1 balun at the OUTPUT exposes
the balun to a wide variety of impedance and reactance that it was never
designed to handle.
