  • Page 9: Introduction

    From 26 MHz to 60 MHz, the Model 3142D antenna with optional end plates exhibits an average 5.5 dB gain improvement. At some frequencies, a 10 dB gain improvement is achieved.

  • Page 10: Tripod Options

    10 dB improvement in low frequency transmit gain and receive antenna factor compared to a same length regular bow tie. With the end plates attached to the Model 3142D bow tie elements, the equivalent dipole electrical length is increased, which decreases resonant frequency and increases efficiency in the 20 MHz to 60 MHz range.
  • Page 11 • Model 7-TR—Constructed of PVC and fiberglass components, providing increased stability for physically large antennas. The unique design allows for quick assembly, disassembly, and convenient storage. Allows several different configurations, including options for manual or pneumatic polarization. Quick height adjustment and locking wheels provide ease of use during testing.

  • Page 18: Attach Bow Tie Elements

    Attach Bow Tie Elements The Model 3142D ships with the bow tie elements detached. To attach the bow tie elements: For stability, mount the Model 3142D onto a tripod or tower. See Mounting Instructions on page 21 for the steps to mount the antenna.

  • Page 19: Attach Optional End Plates

    Attach Optional End Plates For protection, there is a black end cap on each of the bow tie elements. Use a Phillips screwdriver to carefully remove the four screws in each of the bow tie end caps. Remove the end caps. The end caps should be reinstalled when you are done using the optional end plates, so store the end caps and the screws in a safe place.

  • Page 21: Mounting Instructions

    Both horizontal and vertical polarization is easily accomplished when the Model 3142D with the optional end plates is mounted onto a tower, but vertical polarization on a tripod requires special consideration. Because immunity power requirements are many dB lower for vertical polarization, the optional end plates can be removed when mounting vertically on a standard tripod.

Remove the mounting knob from the mounting bracket on the antenna.

  • Page 24: Using The Stinger To Mount To A Model 2175 Minimast

    Using the Stinger to Mount to a Model 2175 MiniMast Do not use the stinger to mount the Model 3142D onto a 4-TR tripod. ° The stinger mount provides on-axis rotation during 90 horizontal or vertical polarization. The stinger enables you to mount the antenna directly to an ETS-Lindgren 7-TR Tripod or mast.
  • Page 25 1. Thread the antenna feed or receiving cable through the center of the boom so that the antenna connector emerges a few inches out of the clamp end of the boom. 2. Attach the cable to the Type N connector at the end of the stinger.
  • Page 26 4. When you reach the back of the balun box, align it with the boom receptacle, and then slide the smaller portion of the balun box into the boom. This will prevent rotation of the antenna unless the boom is being polarized.

  • Page 36: With Optional End Plates

    With Optional End Plates For emissions testing it is recommended that the Model 3142D BiConiLog™ Antenna be used without the optional end plates. The coupling of the endplates to ground will create higher uncertainty values, particularly in the vertical polarization.
  • Page 37 An estimate of the power required, taking VSWR into account, is obtained from: / {1-[(VSWR-1)/(VSWR+1)] = forward (amplifier output) power = new power, as discussed For IEC/EN 31000-4-3 type testing, the antenna tip can be placed at any distance between one and three meters from the EUT as long as the front face plane is illuminated according to the -0, +6 dB uniform field specifications.

    7.0 Typical Data Typical Antenna Factor Distance for the ANSI 3-meter and 10-meter calibrations is measured from the antenna midpoint, and for SAE 1-meter calibrations the distance is measured from the antenna tip. Midpoint is defined as half the distance between the small elements and the bow ties, which is about 45 cm from the small end tip.
