Note
Model DU 1500 L is high power antenna tuner that uses and adjustable reactive network for matching the unbalanced 50 ohm output impedance of transmitters and transceivers to a variety of balanced and unbalanced loads.
It is usable over a frequency range of 1.8-30 MHz. Provision is made for selecting one of three antennas or for bypassing the matching network.
A crossed needles SWR and wattmeter with switchable 200 and 2000 watt scales and selectable peak and average power output reading is included.
The DU 1500 L is designed for connection to transmitters having a 50 ohm nominal output impedance. Connect the coaxial output of your transmitter to the SO-239 INPUT connector on the rear panel of the tuner with a 50 ohm coaxial cable
