  • Page 34 Yagi Troubleshooting Guide GENERAL: Be aware that just because the controller display says an element is a certain length there is no guarantee that it is, the motor could be running backwards due to a miss-wire, the element could have mechanical problems, or a broken wire in the control cable (the motor will run with only one winding driven in some cases) or a faulty driver board.
  • Page 35 Yagi Troubleshooting Guide CABLE PROBLEMS: The control cable uses 4 wires per motor (one motor in each element housing). Each motor has two wires for each of its two motor windings. This test assumes the antenna is connected to one end of the control cable and the measurements are taken at the 25-pin connector that mates to the controller.

  • Page 37 Yagi Troubleshooting Guide Two or More Elements are Swapped: ● This is easy to do if you don’t mark the 4 conductor cables before you tape them along the boom. The SWR will usually be high on every band. Often by changing the controller frequency, while keeping the transmit frequency fixed, the SWR may go quite low at a higher or lower controller frequency.
  • Page 38 Yagi Troubleshooting Guide Mechanical problems can range from an obstruction in the element, usually in the tip, such as packing material or in rare cases fiberglass bumps or imperfections. We check this by running a gauge in the tip but once in a great while that doesn’t catch it. DO NOT ever tape or block the end of the element tip, water can collect and freezing can cause a blockage or trap the element.

    SteppIR Antennas - 3 Element Appendix F: Replacing the Driven Element Bracket (Original 3 element only) For customers who purchased a 3 element antenna before March 2003 your element housing brackets may have been of a different design (Figure 3-C). If you have the original style element housing bracket you will need to install a new style element housing bracket on your boom (Figure 3) before you can mount the new 40m - 30m driven element housing unit.
