HA8DU Tuners DU4000ML Reversible L-Network Manual Antenna Tuner
HA8DU Tuners DU4000ML Reversible L-Network Manual Antenna Tuner is a stylish, exceptional 4kW manual antenna tuner that covers the frequency range of 1.8-30 MHz. Its unique configuration uses a rotary switch to change the high-voltage variable capacitor component, its values and position, to either the input or output side of the 26-turn digital-counter high-quality roller inductor. This is an extremely effective method for matching the 50-ohm transceiver or amplifier to a variety of very low or very high impedance unbalanced antennas. A rotary switch selects the matching network to one of three antenna output connectors or bypass. The auto-ranging cross-needle SWR and wattmeter features 500W and 5000W scales which is backlit and powered by 12VDC. SO-239 connectors are used for the input and outputs. The DU4000ML tunes up to a 10: SWR, handles up to 4000W at 3:1 SWR, across 1.8 to 30MHz. It features a large 3500V, 500pF variable capacitor and a 0.5-23uH silver-plated roller inductor with ceramic body. Dimensions (WHD): 17 x 6.2 x 15.4 in. (430 x 160 x 154mm), less projections. Weight 17.6 lbs. (8 kg).

HA8DU DU4000AL Automatic Antenna Tuners
HA8DU DU4000AL Automatic Antenna Tuners offer advanced automation and display features that are truly unique for a 4kW HF antenna tuner, making this unit the modern-day station command center for automatic band, antenna, and memorized tuning selections. An intuitive 5-color, 5 in. touch screen provides complete control, status, and metering functionality for all station operations, including frequency readout, Forward and Reverse Power and SWR, multiple electronically variable Capacitors "TUNE", and an electronic 11- position Inductor "SWITCH" selector. The DU4000AL also features complete tuning memorization of four rear panel antenna ports as well as direct voltage control of an External 8-port Antenna Switch and Stack Match Switching. It interfaces with all types of Amateur transceivers, with the capability to use an RS-232 interface in-line between specific Yaesu, Kenwood, or Elecraft transceivers and the PC. Or, use this tuner's direct Icom "Remote" CI-V input while connecting the transceiver to the PC by USB. To top it off, the DU4000AL can be operated remotely over the Internet via LAN-Ethernet, supported by a Windows application. The DU4000AL is an automatic memory tuner that you initially program for each antenna and every applicable band segment. Subsequent operations on any preprogrammed frequency range, detected continuously by the transceiver interface, will automatically switch to the correct antenna switch position and tuning values, without transmitting, within 1 to 1.5 seconds, making this tuner truly contest- and DX-ready. The bar has been set very high for the competition. The last tuner you will ever need is the HA8DU DU400AL.
