LDG Electronics AT-1000ProII Automatic Antenna Tuners
LDG Electronics AT-1000ProII Automatic Antenna Tuners are simple to operate! LDG Electronics has refined and expanded their flagship 1 kW automatic antenna tuners. They've retained most of the features of the previous successful models, but now have even easier operation. These tuners still offer two antenna inputs that are front panel selectable with 2,000 memories for each antenna. They store tuning parameters with virtually instantaneous memory recall whenever you transmit on or near a frequency you've used before. Just key-up and it tunes! AT-1000ProII tuners will operate at any power level between 5 and 1,000 watts peak RF input. AT-1000ProII tuners have large, easy-to-read LED bar-graph meters that display two selectable power ranges (100 and 1,000 watts), as well as SWR. An optional 4.5 in. analog meter, model M-1000, shows SWR and 100 or 1,000 watt ranges of forward or reverse power, in peak or average modes. AT-1000ProII tuners will interface with many popular transceivers, enabling transceiver "TUNE" button control of AT-1000ProII operation. Dedicated control buttons allow you to fine-tune capacitance and inductance on those rare occasions when the AT-1000ProII can't find a perfect match by itself. AT-1000ProII Automatic Antenna Tuners will tune from 1.8 to 54.0 MHz continuously, and will match an amazing range of antennas, from Yagis and dipoles to inverted-Vees and slopers. Virtually any coax-fed antenna may be tuned, from 6 to 1,000 ohms impedance across HF, and from 16 to 150 ohms on 6 meters. Initial tuning time is usually under 10 seconds. If you're transmitting near a frequency with stored tuning parameters, it will set those parameters in under 200 milliseconds. The use of longwires or antennas fed with ladder line will require an external balun, not included. Note: For additional information, please look at the files under the "Documentation" tab. For a versatile automatic antenna tuner that will handle some real power, remember these LDG Electronics AT-1000ProII Automatic Antenna Tuners from DX Engineering!

LDG Electronics AT-200ProII Automatic Antenna Tuners
There was a time when 100 watts was a lot of power. Today, more and more transceivers feature 200 watts of output. Even though many of these modern radios feature a built-in tuner, the tuners' range and features are usually quite limited. Break through those barriers with LDG Electronics AT-200ProII Automatic Antenna Tuners! They're designed for this new generation of rigs and are specifically recommended for Ten-Tec and tube radios. Many QRP operators have a small 100-150 watt amplifier for times when you need a few more S-units. The AT-200ProII tuners are ideal for this kind of operation; their minimum required power is only 5 watts, but they will handle higher power as well. The AT-200ProII tuners will handle up to 250 watts SSB or CW (75 watts RTTY, FT8) on 1.8-30 MHz, and 100 watts on 54 MHz. They feature LDG's state-of-the-art, processor-controlled Switched-L tuner. The AT-200ProII tuners will match virtually any kind of coax-fed antenna, including Yagis, dipoles, inverted Vs, slopers, loops, or just about anything. They will typically match a 10:1 SWR down to 1.5:1 in just a few seconds. You can also use the AT-200ProIIs with end-fed antennas, random wires, and antennas fed with ladder line with the optional LDG balun. Operation couldn't be simpler--while transmitting a carrier, just press the tune button. An automatic tuning cycle will begin and then end a few seconds later with the tuners set at the lowest SWR (almost instant for frequencies stored in memory). The AT-200ProII automatic memory tuners are the latest in a long line of innovative LDG Electronics tuners and will allow you to get the most out of your Kenwood, Yaesu, Ten-Tec, or ICOM radio that operates at higher power. Additional features include: * 5 to 250 watts SSB and CW (100 watts on 6M, 75 watts HF Digital, RTTY, PSK, FT8) * Easy-to-read LED bar graph display for RF power, SWR, and status * LEDs for antenna position and bypass * 4,000 memories (2,000 for each antenna) for instantaneous band changing * 2-position antenna switch with memories for four antennas on each position * Tuning time: 0.5 to 6 seconds full tune, less than 0.1 second memory tune * Built-in frequency counter for memory operation * Tunes 6 to 800 ohm loads (16 to 150 ohms on 6m), 6 to 3,600 ohms with optional 4:1 balun * Includes 6 ft. DC power cable * Power requirements: 11 to 16V DC at 750 mA max during tuning * Weighs 2 lbs. Note: For additional information, please look at the files under the "Documentation" tab.

Palstar BT1500A 1500 Watt Double L Balanced Antenna Tuners
Palstar BT1500A 1500 Watt Double L Balanced Antenna Tuners are the only 1,500 watt, double-L network antenna tuners on the market today. BT1500A tuners feature two tandem mounted, precision ceramic roller inductors for a truly balanced tuner. A dual section capacitor provides the correct amount of capacitance for both low-band and high-band operation and is relay-switchable between the input and output side to provide the maximum possible range of impedance matching. So, why buy a balanced tuner? Joel Hallas described the problem many antenna tuners experience in his September 2004 QST article on balanced tuners. He wrote, "Unfortunately, the typical random sized center-fed antenna with random length ladder line feed has an impedance at the feed point that varies dramatically with frequency. The result can be heating and loss (and occasional damage) at the balun ... the classic solution has been the use of an inherently balanced tuner." In his QST article, Joel Hallas was reviewing Palstar's former model AT1500BAL as a high-power solution for amateur operators looking for a balanced tuner. Since that review, the engineers at Palstar have reengineered their AT1500BAL tuner inside and out and reintroduced it as their BT1500A. Palstar BT1500A 1500 Watt Double L Balanced Antenna Tuners feature two precision ceramic-body roller inductors mounted in tandem. The massive dual-section capacitor can be switched, with a front panel controlled relay, from the input side to the output side of the tuning network to provide maximum flexibility in tuning range. Another front panel controlled relay switches the two sections of the capacitor for high and low-band coverage. Plus, as a final touch to the BT1500A, Palstar's engineers added the peak and peak hold dual cross-needle metering found in our popular PM2000A wattmeter. Here are the specifications on these great double balanced antenna tuners; model BT1500A: -- Power rating: 1500 watts PEP -- Relay switched Hi/Low-Z impedance range -- Relay switched Hi/Low-C variable capacitor -- Total inductance of 44uH for greater impedance range on 160m -- Matching range: 160m - 20m (2500+/-j2500), 10m - 15m (1000+/-j1000) -- Two tandem-mounted ceramic body roller inductors - silver plated wheel and wheel shaft -- One turns counter and one crank handle drive both inductors -- Low minimum capacitance, dual-section variable capacitor (960pF/65pF @ 4.5kV) with Vernier drive for smooth accurate tuning -- Ferrite 1:1 input balun, required on double balanced tuners -- Peak and peak hold dual cross-needle metering (1-2 sec hold) with backlighting -- Cabinet metalwork is heavy 11 gauge (0.090 in. thick) Iridite®-coated aluminum; powder coated front panel and top cover Note: For additional information, please look at the files under the "Documentation" tab. Please remember that Palstar BT1500A 1500 Watt Double L Balanced Antenna Tuners are highly-specialized tuners, designed to do only one thing--tune balanced-line feed antennas--and do it well.
