LDG Electronics Antenna Tuners
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. If you are running an older, high-output tube rig, a newer 200 watt rig, or have a small amplifier to give your QRP rig a boost, consider LDG Electronics AT-200ProII Automatic Antenna Tuners from DX Engineering!

LDG Electronics AT-600ProII Automatic Antenna Tuners
Today, more and more mid-sized amps with 500 watts of output are becoming popular. LDG Electronics AT-600ProII Automatic Antenna Tuners are designed for this new generation of power levels. AT-600ProII tuners will handle up to 600 watts SSB and CW and 300 on RTTY (1.8-30 MHz) and 250 watts on 54 MHz. They feature LDG's state-of-the-art, processor-controlled Switched-L tuner. Their front panel bar graph meter, and the optional sweep-needle remote meter, displays all tuner and power readings. AT-600ProII tuners will match virtually any kind of coax-fed antenna, including Yagis, dipoles, inverted Vs, slopers, loops… 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 AT-600ProII tuners with end-feds, random wires, and antennas fed with ladder line just by adding a balun. These tuners feature two antenna ports with a front-panel indicator showing which is in use, and separate memory banks for each antenna. Easy-to-read LED bar graph meters showing RF power, SWR and tuner status, tactile feedback control buttons, and an LED bypass indicator complete the user interface. As with most RF Sensing autotuners, AT-600ProII tuners will automatically tune with any rig without the need for accessory band-switching cables. An OPTIONAL antenna tuner radio interface cable automates transceiver control, if supported by your particular transceiver. An optional Analog Remote Meter with 6 ft. connection cord provides a touch of Amateur tradition. Any power source from 11-16 Vdc may be used. The AT-600ProII tuners only draw up to 750mA. Additional LDG AT-600ProII features include: * 4,000 memories for instantaneous band changing * 2-position antenna switch with memories for each position * Tuning time: 0.5 to 6 seconds full tune, 0.1 second memory tune * Optional antenna tuner radio interface cable available * Built-in frequency counter for memory operation * Tunes 6 to 800 ohm loads (16 to 150 ohms on 6M) * DC power cable * Weighs 3 lbs. Note: For additional information, please look at the files under the "Documentation" tab. If you power up with as much as 600 watts, LDG's got your back with the AT-600Pro tuners. LDG antenna tuners are recognized for their ease of use and reliability. Order your LDG Electronics AT-600ProII Automatic Antenna Tuners from DX Engineering.

LDG Electronics RT-100 Combo Remote Antenna Tuners
LDG Electronics RT-100 Combo Remote Antenna Tuners are 100 watt coax-in/coax-out remote tuners designed to be placed near the feed point of the antenna. If you are worried about power loss due to Standing Waves in your feed line, the RT-100 is the answer! Place the RT-100 near the feed point and then virtually eliminate all feed line loss due to SWR. RC-100 Remote Tuner Consoles are control units supplied with the RT-100 Combo automatic tuner. These consoles provide coaxial DC power injection via their Bias T connection. They also add a convenient on/off switch, power indicator, and TUNE button! LDG RT-100 combos include these features: * 0.1 to 125 watt power range (SSB and CW), 30 watt digital * 2,000 memories for instantaneous band changing * Powered over the coaxial cable * RC-100 Controller (included) provides DC power and control to tuner * Weather-resistant ABS enclosure with gaskets * Tuning time: 0.1 to 6 seconds full tune, 0.1 seconds memory tune * 1.8 to 54.0 MHz coverage * Built-in frequency sensor * Tunes 4 to 800 Ohm loads (16 to 150 Ohm on 6M), 16 to 3,200 Ohms with optional 4:1 balun * For Dipoles, Verticals, Inverted Vs. Beams, or any coax fed antenna * Includes U-bolt for pipe mounting * Optional external balun allows tuning of random length, long wire, or ladder line fed antennas * Small size: 6. 5-in. long, by 6.0 in. wide, by 2.5 in. high * Weight: 1 pound Note: For additional information, please look at the files under the "Documentation" tab.

LDG Electronics AT-100ProII Automatic Antenna Tuners
LDG Electronics AT-100ProII Antenna Tuners are the next step in the evolution of the automatic tuner. These desktop tuners cover all frequencies from 1.8 to 54 MHz and will automatically match your antenna in no time. These tuners feature a 2-position antenna switch, allowing you to switch instantly between two antennas. Updated features include an LED indicator for antenna selection and an LED to indicate when in bypass. AT-100ProII tuners require just 1 watt for operation, but will handle up to 125 watts, making them suitable for everything from QRP to a typical 100 watt transceiver. These tuners include 2,000 memories for each antenna; automatically storing tuning configurations for each frequency and band as you use them. Frequency-sensing circuitry lets the AT-100ProII tuners "know" your operating band and frequency. Whenever you transmit on or near a frequency you've used before, AT-100ProII tuners can retune from memory almost instantly. Rugged and easy-to-read LED bar graphs show power and SWR, and a function key on the front panel allows you to access a data-like mode and status. AT-100ProII tuners use latching relays, which retain the tuned configuration indefinitely, even when powered down. They use LDG's state-of-the-art, processor-controlled Switched-L tuning network. They will match dipoles, verticals, inverted Vs, or virtually any coax-fed antenna. Features include: * 1 to 125 watt power range (SSB and CW), 50W on 6M, 50W Digital * Tuning time 0.5 to 6 seconds full tune, 0.25 sec memory * Selectable user parameters: auto/semi, 125/12.5 watt scale, auto-tuning threshold, and more * Tunes 6 to 1,000 ohm loads (16 to 150 on 6M) * Optional external balun allows tuning random-length, long wire or ladder line fed antennas * Includes DC power cable * Power requirements: 11 to 16VDC at 500 mA maximum Note: For additional information, please look at the files under the "Documentation" tab. If your rig doesn't have a built in tuner, or lacks the wide range required for some applications, consider LDG Electronics AT-100ProII Antenna Tuners from DX Engineering!
