DX Engineering Transmit Four Square System Phasing Unit operating Guide
Description
This resource provides technical documentation for the installation and operation of the DX Engineering TFS Series Transmit Four Square System Phasing Units. It details the setup for monoband vertical arrays on 160, 80/75, and 40 meters, specifically addressing models such as the DXE-TFS4-160B. The guide covers system components, required parts, and a discussion of vertical antenna selection, including a table of DX Engineering Monoband Vertical Antennas. Installation procedures are outlined, encompassing site selection, four square layout, topographical considerations, and noise source mitigation. Specific instructions are provided for mounting the phasing unit, antenna feedline connections, and control wire routing. The document also includes details on radial system implementation, with a table of radial wire lengths for 160, 80, 75, and 40 meters, and procedures for tuning the vertical antennas. Operational aspects of the Four Square Control Console are described, including front and rear panel functions, control logic (Table 4), and typical transceiver/amplifier interconnections. Lightning protection and initial system testing are also addressed. The system enables directional control with gain in four directions or an omni-directional pattern.
