ACOM 2000A Automatic HF Linear Amplifiers
ACOM 2000A Automatic HF Linear Amplifiers are the world's most advanced amplifiers designed specifically for hams. These amplifiers were the first to include fully-automatic tuning and sophisticated digital-control capabilities. ACOM's revolutionary 2000A amplifiers deliver maximum legal power in all modes and operate on all amateur HF bands 160 to 10 meters. Be sure to read the SPECIAL Note, below. These amplifiers follow your transceiver's band and frequency automatically in far less than a second. No special cables are required: Just a "dit" on CW or "AHH" on SSB is enough for instant band and band segment changes. ACOM 2000A amps break every amateur band into multiple frequency segments. The user can store up to ten (10) sets of tuning adjustments for every frequency segment - allowing individual settings for multiple antennas on each band. By completely eliminating time-consuming tune-up procedures, ACOM 2000A linear amplifiers give contesters a real edge. At the core of the ACOM 2000A is a classic HF amplifier design that employs two matched 4CX800A high-performance ceramic-metal tetrodes for maximum efficiency. ACOM uses these rigorously tested tubes with today's most advanced digital control technology to create an amplifier with outstanding performance, features and reliability. Measured third and fifth order IMD are typically 40dB and 45dB down, respectively. Typical harmonic emissions are as low as -55dBc (second) and below -70dBc (for third and above). Thus, probability of QRM, BCI or TVI is dramatically minimized. ACOM's 2000A remote diagnostic features and modular design ease fault isolation and repair. The protection system makes damaging one of these amplifiers difficult. Information on the 12 most recent protection trips is stored in an INFO BOX for remote diagnostics via phone line, PC, and Internet. Full break-in (QSK) is based on a built-in vacuum relay. Transmit/receive switching sequence is secured by a dedicated microprocessor. * Frequency Coverage: All Amateur Bands 1.8-29.7 MHz * Power Output: 1,500W PEP, 1,500W continuous carrier (the external auxiliary fan must be installed for operations of continuous carrier transmissions longer than 15 minutes * Hum and noise: Better than 35dB below rated output * Harmonics Output Suppression: Better than 50dB below rated output * Input and Output Impedance: Nominal values: 50 Ohm unbalanced output; Input circuit: broadband, VSWR less than 1.3:1, 1.8-29.7 MHz Amateur Bands (no tuning, no switching); Relay Bypass Throughput: VSWR less than 1.1:1, 1.8-29.7 MHz Amateur Bands * Automatic Tuning: Load Impedance Matching - less than 3 seconds; Band Change - less than one second; Segment Change - less than 0.2 seconds * RF Gain: 14.5dB, frequency response less than 0.5dB (50 to 60W drive power for rated output) * ALC: grid-current derived, -11V max, rear panel adjustable * Primary Power: 180-264V (200, 220 and 240V nominal taps, 10 percent tolerance), 50-60Hz, single phase, 3,500VA consumption at rated output * SPECIAL Note: Order part number AOM-2000A to wire the AC plug yourself; order part number AOM-2000A-240 for pre-wired 240 volt operation * Complies CE safety and electromagnetic compatibility requirements, as well as FCC regulations * Size: W 17.3 x 19.7 x H 7.1 in. Weight: 36 kg * Operating environments: temperature range: 0 to 50 degrees C; Humidity: up to 95 percent at 35 degrees Celsius * Altitude: up to 3,000m above sea level without output degradation Note: For additional information, please look at the files under the "Documentation" tab. Get the most advanced legal-limit HF amplifier for your shack. Order ACOM 2000A Automatic HF Linear Amplifiers from DX Engineering… today! Note: During and after your amplifier's warranty period, DX Engineering can direct you to the appropriate location for repairs for ACOM amplifiers. That facility will charge a repair fee for services outside the warranty period.

Diex Antennas Two-Band Trap Shortened Rigid Rotatable Dipoles
Diex Antennas Two-Band Trap Shortened Rigid Rotatable Dipoles offer high performance multi-band HF operations, and they are an excellent choice where there's not enough space for a full-size dipole or Yagi. Crafted with precision in Brazil using quality materials, these aluminum tubing antennas are designed to withstand tough environments assuring long-lasting, exceptional performance. They are packed partially assembled, saving valuable time and effort. Typically mounted on a rotating mast, these unique multi-band HF antennas provide high-band directionality depending upon installed height above ground. Given the nature of shortened low-band antennas with limited SWR bandwidth, these antennas feature the flexibility of physical adjustment to set the lowest SWR to a specific frequency. DIEX Antennas Two-Band Trap Shortened Rigid Rotatable Dipoles power handling is 1500W PEP SSB, which is further limited if using an antenna tuner. NOTE: Diex Antennas recommends that a directional HF antenna should be mounted on a tower at a minimum height of 33 to 50 ft. (10 - 15 meters) above ground level and must be installed in the clear, away from power lines, trees, buildings or other towers and antennas.

Palstar PM2000A Watt Meters
Palstar PM2000A Watt Meters measure and display SWR, forward power up to 2,000 watts, and reflected power simultaneously on a dual movement meter system that operates in the frequency range from 1.8 MHz to 60 MHz. Accuracy of the readings is assured with the PM2000A shielded directional coupler. These backlit meters, which can display average or peak power readings, now have a convenient peak hold function and a push-button selection for 300 watt and 2,000 watt ranges. PM2000A Watt Meters are the improved version of Palstar's best-selling WM150 Wattmeters. When QST tested the PM2000As' predecessor, they found it to be the only wattmeter with true Active Peak Reading. The PM2000As are one of the new generations of watt meters from Palstar. All of the features of the WM150 are integrated into PM2000A meters, now with increased power capability up to 2kW and two-second peak hold metering. To top it off, just like on Palstar tuners, the PM2000A meters have an 11 ga. (0.090 in.) iridite-treated aluminum case with a powdercoated front panel and top cover. Rear panel SO-239 (UHF female) connectors are provided for coaxial cable RF input and output, and a 2.1mm connector provides input for 12 Vdc at less than 200 mA to run the meter circuit and backlight. Note: For additional product information, please look at the files under the "Documentation" tab. Simple to hook up and use, Palstar PM2000A Watt Meters take the guesswork out of your inline RF power and SWR measurements. Order yours from DX Engineering today!
