  • Page 2: Specifications

    Features The DU 3000T and DU3000TB tuners optimize the performance of your antenna and transmitter or SWL receiver by providing adjustable impedance matching. The DU 3000 series also measure the Power and Standing Wave Ratio (SWR), which allows you to tune the indicated SWR to the lowest possible value for the selected transmit frequency.

  • Page 7: Installation

    Installation Select a location for the DU 3000 that allows the connectors to be free of any possible contact during operation. WARNING: Some balanced or end fed antennas will produce high RF voltages at the feedthrough connectors. Severe RF burns may result while in transmission if these connectors get in contact with the skin.
  • Page 8 Tuning 1. Select the band and frequency of desired operation. 2. Set INPUT, OUTPUT and INDUCTOR controls to the suggested settings before applying transmitter power. Actual settings may vary from one antenna to the other. 3. Set up your transmitter to a low power output. If your transmitter has a TUNE or RTTY position, select that position.
  • Page 9 Notes 1. An SWR or 1:1 is best, but an SWR as high as 2:1 may be acceptable. Check you transmitter manual for details. 2. If you can’t get an acceptable SWR, lengthen or shorten you antenna and/or feedlines and retune. 3.
