Providing Frequency coverage from 1.8 to 30MHz and with two antenna outputs, the mAT-1500PROII also provides antenna switching. Depending on how cables are connected, the tuner will operate in three modes: Icom, Yaesu or General, General mode also allows for remote operation of the tuner. The front panel has a 4.3 inch high resolution display that provides information as to the current operating mode, forward power in both PEP and Average power, with a bar scale that can show three ranges: 15W, 150W, and 1500W; in addition to the power output the antenna system SWR is also shown along with current toggleable settings such as antenna output selection, PTT status, which of the four buttons (LUP, LDN,CUP or CDN) was pressed last, and finally the current status of the tuner. The front panel also has 6 additional buttons for controlling if the PTT signal is passed from the tuner to an amplifier (effectively putting the amplifier in bypass), an online button which controls the tuner being in an online or bypass state, a Tune button which starts a tuning cycle when the tuner is in General mode, a range button which changes the displayed scale of the RF indicator on the display, an antenna select button which allows for changing the antenna jack that is used on the tuner, and finally, a power and screen background setting which allows for tuner power to be cycled in General mode as well as the screen brightness and background color to be changed (if the tuner is in Yaesu or Icom mode, the power function of this button is not used.) The rear panel features 3 SO-239 jacks, one for RF In, and two antenna connections. a ground lug and a handful of connection ports for interfacing with the radio. If the user wants the tuner to follow the frequency of the radio with no additional input, the user can connect the appropriate control cable (sold separately) to the radio and the Icom/Kenwood or Yaesu jacks on the back of the tuner. In these modes, the tuner will receive power from the radio and will power up with the radio and not require a dedicated power connection. In general mode, a connection to the DC in jack is required. A PTT in and Out jack both allow for the transceiver to send a PTT signal to the tuner and for the tuner to pass that PTT signal on to the amplifier.

Palstar AT4K 2500 Watt Antenna Tuners
One of the all-time great antenna tuners, the Palstar AT4K 2500 Watt Antenna Tuners helped build the Palstar reputation for high-quality and "Built-Like-A-Tank" durability. Unwilling to rest on their laurels over the years, Palstar has added new features to the classic. The most recent addition to the AT4K is the Active Peak and Peak Hold Wattmeter, identical to that used in their PM2000A Wattmeter. The frequency-compensated, lighted, dual-movement SWR/wattmeter may be switched between 300 watt and 3,000 watt scales for peak or average power readings. Now, the selection between unbalanced or balanced output is relay switched with a front panel control on the AT4K, eliminating the need to place a jumper strap on the back panel to make the changeover. Two coaxial and one bypass unbalanced output are handled by the extra heavy-duty ceramic 6-position 7 kV 10 Ampere RF switch assembly. The AT4K surpasses antiquated unbalanced tuners that were built with a 4:1 balun at the OUTPUT of the matching network. In those tuners, the balun was exposed to a wide range of impedance and reactance that it was never designed to handle. 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, an impedance of 50 ohms is presented to the input and output of the balun, which allows it to properly perform its important transformation job. Palstar AT4K 2500 Watt Antenna Tuner features: --Power rating of 2,500 watts single tone continuous --T match circuit with impedance matching range 8 ohms to 2,000 ohms --Custom large value variable capacitors, 460pF at 6 kV --10 Ampere silver plated ceramic body roller inductor crank, handle-driven --11 ga.

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.
