Antenna Tuners
AT5K 3,500 Watt Antenna Tuner
Nicknamed the “Rock Crusher,” this American-
made Palstar AT5K 3,500 Watt Antenna Tuner
delivers an impressive 3,500 watts single
tone continuous with low losses, and 5,000
watts PEP performance at certain impedance
ranges. The AT5K tuner o ers a wide impedance tuning range from
1.8 through 22 MHz with limited impedance tuning from 22 to 29.5 MHz.
The AT5K tuner provides balanced output with a high power 5,000 watt PTFE cable balun
at the input of the tuner circuit. When the network is properly tuned, a 50 Ω impedance
will be presented to the input and output of the balun for maximum e iciency. This tuners
is designed to handle both balanced line feeds and unbalanced coax feedlines.
• Fan-cooled for extended 100% duty cycle operation
• Full-performance T-match circuit, impedance matching from 8 to 2,000 Ω
• Custom large value variable capacitors, 600pF at 6 kV
• 10 amp silver plated ceramic body roller inductor handle-driven crank
• 11-gauge aluminum chassis, powdercoated on front and top
• Power connector and cable included

AT4K 2,500 Watt Antenna Tuner
The legendary AT4K 2,500 Watt Antenna
Tuner built the Palstar reputation for high
quality and durability. Updated for the 21st
century, the AT4K now has a switchable,
dual-movement active peak and peak hold
wattmeter. The selection between unbal-
anced or balanced output is relay-switched
with a front panel control on the AT4K.
The AT4K T-matching network uses a 1:1 unbalanced-to-balanced transformer in the input
of the network. When the network is properly tuned, an impedance of 50 Ω is presented to
the input and output of the balun.
• T-match circuit with impedance matching range from 8 to 2,000 Ω
• Custom large value variable capacitors, 460pF at 6 kV
• 10 Amp silver plated ceramic body roller inductor handle-driven crank
• 11-Gauge aluminum chassis, powdercoated on front and top

AT2KD Di erential Antenna Tuner
Palstar’s AT2KD Di erential Antenna Tuner is
American-made, with impedance-matching
networks that optimize the performance of
your antenna with your transceiver or SWL
receiver. It o ers 160 through 6 meter band
coverage and handle up to 2,000 watts PEP
power. Simply put, the AT2KD is the highest
quality di erential-T antenna tuner on the market!
This tuner has two impedance-matching controls with a 6:1 Vernier reduction drive for
capacitor tuning with precision and accuracy. A turns counter-indexed inductor crank
handle makes coarse tuning adjustments easy. Using a T-type circuit configuration makes
adjustments simple because it reduces the number of knobs and eliminates false peaks. A
12 Vdc power connector and cable are provided for the meter circuit for each tuner.
• Input tuning: 5 kV dual-stator di erential capacitor (430pF/13pF/430pF)
• Inductance: 25 uH roller inductor; 12-gauge wire wound on steatite ceramic core,
silver plated bar/wheel
• Frequency coverage: 1.8-54 MHz
• Power: 2,000 W PEP SSB, 1,500 W single tone
• Impedance range 20 to 1,500 Ω, 1.8-30 MHz lower power for lower Z range

AT2K 2,000 Watt Antenna Tuner
Building upon Palstar’s impressive
AT1500CV tuner, this AT2K 2,000 Watt
Antenna Tuner features a new, smaller
roller inductor, allowing the AT2K to
tune from 160 meters to 6 meters. It
can match dipoles, center fed doublets,
Verticals, end-fed wire, delta loops, beams,
Windoms, inverted v ees, and many more antenna types.
The AT2K features a 6-position antenna selector switch and Peak/Peak Hold metering in
two ranges, 300 and 3,000 watts. Standing Wave Ratio measurements are displayed with
this illuminated cross-needle meter. Its chassis is made of 11-gauge aluminum with a
powdercoated finish on the front and top cover.
• Impedance range 20 to 1,500 Ω from 160 to 6 meters (assuming resistive load)
• Low minimum custom variable capacitors, 15pF to 400pF at 4.5 kV
• 26 uH 5 kV ceramic body roller inductor with turns counter
• Silver plated inductor wheel sha and contact wheel
