Overview

Palstar AT5K-HP 3500 Watt Antenna Tuners

Palstar AT5K-HP 3500 Watt Antenna Tuners are special high-power tuners, made in the American ham radio tradition. AT5K-HP tuners are identical in almost every function to the AT5K tuners, which have been nicknamed the "Rock Crusher" and are fast becoming the tuner of choice among amateurs who demand the best and most robust antenna tuner on the market.

Some hams already have a great meter, such as the Palstar PM2000A, and do not require a balun to be built into their high power tuner. So, Palstar AT5K-HP tuners are their solution, because they are specially built without an internal balun and they do not have a metering system.

Palstar AT5K-HP 3500 Watt Antenna Tuners still offer all of the power handling you need, coming in with an impressive rating of 3,500 watts single tone continuous with low losses, and 5,000 watts PEP performance at certain impedance ranges. AT5K tuners offer a wide impedance tuning range from 1.8 through 22 MHz and a slightly limited impedance tuning range from 22 to 29.5 MHz.

Inside the AT5K-HP, you will find massive custom large-plate (600 pF) variable capacitors rated at 6 kV. This high capacitance means unsurpassed performance on 160 meters, while specially designed non-metallic end plates allow for a minimum capacitance of only 23 pF for 10 meter tuning, which is unusually low for a variable capacitor this large. Equally massive is the 35 uH, 10 Ampere, 7 kV, ceramic-body inductor, which is wound with 10 ga. plated copper wire with a silver-plated wheel shaft and contact wheel. Two coaxial and one bypass unbalanced outputs are handled by the extra heavy-duty ceramic wafer 6-position 7 kV, 10 Ampere RF switch assembly.

Palstar AT5K-HP 3500 Watt Antenna Tuners feature:

-- Power rating of 3,500 watts single tone continuous
-- Classic full-performance T- match circuit with impedance matching range 8 ohms to 2,000 ohms
-- Custom large value variable capacitors, 600pF at 6 kV
-- 10 Ampere silver plated ceramic body roller inductor crank, handle-driven
-- 11 ga. (.090 in. thick), iridite-treated aluminum chassis, with durable powder coating on front panel and top cover
-- Power connector and cable included, 12 Vdc to power the LEDs
