The AT4K is a 2500 watt antenna tuner built according to Palstar\'s reputation for high-quality and \"Built-Like-A-Tank\" durability.The AT4K solves a problem suffered by the typical unbalanced tuner that has a 4:1 balun at the OUTPUT of the matching network. This exposes the balun to a wide range of impedances and reactances 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.
