Palstar AT5K 3500 watt antenna tuner: the rock crusher


Palstar's most powerful tuner ever!
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.
Inside the AT5K you'll find massive custom large plate (600 pF) variable capacitors at 6 kV. Equally massive 10 Amp 7 kV CERAMIC body inductor wound with #10ga plated copper wire with silver-plated wheelshaft, contact wheel, and hardware (35uH).
Also, Palstar engineering has incorporated the technology found in our popular WM150 watt meter into this tuner to provide dual cross-needle metering with active peak and peak hold. See below for more technical specifications.
There aren't any revews on the AT5K yet, but The AT4K was reviewed in the Sept 2004 edition of QST or check out the user reviews on eHam.net.
