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!

Palstar AT-500 600 Watt PEP Antenna Tuners
Introducing Palstar AT-500 600 Watt PEP Antenna Tuners. All of the quality and features that Hams worldwide have come to expect from Palstar are now available in these compact, lower-power, lower-priced AT-500 tuners. Covering the 160 through 6 meter bands, AT-500s utilize only 2 controls to operate for tuning, providing for maximum ease of use, and a more compact manual tuner. These tuners feature a Vernier drive differential tuning split-stator capacitor and a smaller, precision ceramic body, crank handle roller inductor. This combination allows for operation on 6 meters, while a relay-switched add-on inductor allows for 160 meter tuning. Just like the big tuners, AT-500s offers the convenience of a 6-position mode switch for multiple antenna feedlines and an external dummy load. AT-500 tuners also feature Palstar's active Peak and Peak Hold dual cross-needle metering found in our popular PM2000A wattmeter. They are made with an 11 ga. (0.090 in. thick) iridite-treated aluminum metalwork and durable powdercoated finish on the front panel and top cover. Covered under a 1-year factory warranty, Palstar AT-500 tuners are ideal as an entry-level selection, if you want to buy a high-quality, American-made product. Features of Palstar AT-500 600 Watt PEP Antenna Tuners: -- Power rating: 600 watts PEP SSB; 500 watts CW -- Active cross-needle peak and peak hold metering with backlighting -- Meter power ranges 0-300 watts/0-1000 watts -- Impedance matching range 20 ohms to 1500 ohms -- Output to both balanced and unbalanced lines -- 4:1 ferrite current balun handles balance line feeder -- Easy and quick tuning with only two controls -- Differential capacitor tuning with 2 stators and 1 rotor (360pF - 14pF - 360pF @ 2.5kV) -- Palstar designed and built 15uH ceramic body roller inductor -- 12 Vdc power connector and cable included Note: For additional information, please look at the files under the "Documentation" tab.
