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.
