Both braids are 1" wide by 9" in length. Connect one braid from the antenna feedpoint located on Red "+" the base section of the antenna to the terminal on the DXE-UN-43 UNUN closest to the on the label as shown in Figure 5. Do not over tighten the wing nuts. Hand tighten them only, do not use pliers or other tools to over tighten the wing nuts. - Page 10 The feedpoint on the antenna bas section can be facing forward, or can be facing to the left (when looking at the front of the antenna). Note: Ensure the"-" braid connection to the Radial Plate does not interfere with the tilting process. If this is a problem, then remove the braid from the UNUN when tilting the antenna.
