AT4K Antenna Tuner

The Palstar AT4K 2500 watt antenna tuner covers 160 to 10Meters with a power rating of up to 2500 watts PEP.

The AT4K is the tuner thatbuilt Palstar\'s reputation for high-quality and \"Built-Like-A-Tank\"durability.

Unwilling to rest on our laurels, over the years Palstar has addednew features to our classic.

The most recent additions are the Active Peak and Peak HoldWattmeter identical to that used in our PM2000A Wattmeter,

and front panelcontrolled relay switching between balanced line and coax output, eliminatingthe need to place a jumper strap on the back panel to make the changeover.

Featuring a 6 position antenna selector switch, the AT4Koffers forward power metering in two ranges, 300 and 3000 watts.

The AT4K solves a problem suffered by the typicalunbalanced 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 wasnever designed to handle.

The solution: The AT4K T-matching network utilizes a 1:1unbalanced-to-balanced transformer in the INPUT of the network.

When the networkis properly tuned, a 50 Ohm impedance will be presented both to the input andoutput of the balun,

which allows it to properly perform its importanttransformation job.

Add 11 Ga. (.090\" thick) iridite-treated aluminummetalwork and durable powder coated finish on the front panel and top cover, andyou have the AT4K,

a premium quality antenna tuner.

I have used this antenna tuner for about two weeks so it\'svirtually like brand new.

My antennas are all spot now, so I don\'t needit.

Works and looks absolutely perfect!

Good Luck, 73, Chris
