Quick Overview

Tuner

Details

  • The word is spreading about Palstar's unique, high-end amateur radio products. Carrying on in the Palstar tradition for products of the highest quality designed by Hams for Hams. The American made AT4K tuner is no exception.
  • The American made 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. The solution: the AT4K. The AT4K T-matching network utilizes a 1:1 unbalanced-to-balanced transformer in the INPUT of the network. When the network is properly tuned, a 50 ohm impedance will be presented both to the input and output of the balun, which allows it to properly perform its important transformation job.
