    When the power is “off” on your controller, there is still a very small amount of power feeding to the stepper motors, to effectively “lock” them in place. This reduces the need for calibration of the antenna. Page 13 Support: steppir.com/support ⚫ Tel: 425.453.1910 ⚫ support@steppir.com...

  • Page 15: Antenna Overview

    PREAMBLE ANTENNA OVERVIEW The UrbanBeam Yagi antenna uses a loop element for 30m and 40M. The loop elements used for 40m and 30m are 50% shorter than a full size dipole element, with very little sacrifice in performance (-0.6dB). The UrbanBeam is a dipole on 40m and 30m. The UrbanBeam performs as a 2 element Yagi on 20m-6m.

    It’s important to pay attention to the orientation of the EHUs on the boom, making sure that the ESTs (where the loop elements attach) are positioned to be closest to the ends of the boom. Page 16 Support: steppir.com/support ⚫ Tel: 425.453.1910 ⚫ support@steppir.com...

    PREPARING THE BOOM ASSEMBLY EHU Mounting Locations EHU CENTER-TO-CENTER SPACING MEASUREMENTS It is critically important that the center-to-center spacing is correct when assembling your SteppIR Ya- gi. Use Figure 1.00 for placement of each of the elements. Start from the left edge of the boom and measure from there.

  • Page 18: Ehu Placement

    EHU Placement ELEMENT HOUSING UNIT (EHU) PLACEMENT The UrbanBeam Yagi has two EHUs on the boom. One is a Driven element on 40 meters through 6 me- ters, while the other is a Director on 20 meters through 6 meters.

  • Page 19: Ehu Overview

    ELEMENT HOUSING UNIT (EHU) OVERVIEW When wiring the EHUs on the UrbanBeam Yagi, it is important to know that there are two different types of EHUs. One of the EHUs is the Driven element, and connects to the coax cable from the radio.

SteppIR offers saddle sizes in 1-3/4”, 2”, 2-1/4”, 2- 1/2” and 3”. Since the vast majority of installations of the URBANBEAM comes with the standard 2 inch sad- dles, that is the verbiage used in the instructions that follow.

    TROUBLESHOOTING THE URBANBEAM YAGI TROUBLESHOOTING TIPS SteppIR antennas are all powered by stepper motors, hence the name. Stepper motors function by rotating the shaft a specific number of “steps” per revolution. The SDA 100 directs the stepper motors to extend the elements a particular number of steps to the required length.

    3.0) when measuring the voltages, a suggestion would be to use a bare 25 pin D-Sub to plug into the SteppIR controller and then insert a paper clip to penetrate the pin hole. Usually about .75″ long will do the trick. One paper clip being longer than the other also helps.
