1.0 Introduction The ETS-Lindgren Model 3143B BiConiLog™ Antenna is designed as a dual-purpose antenna that can be used for both immunity and emission testing. From 26 MHz to 6 GHz, the Model 3142E exhibits an average 5.5 dB gain improvement. Applications for the Model 3142E include emissions testing, immunity measurements, and medical equipment testing.
Model 3143B shown in horizontal polarization The Model 3143B includes a stinger mount; it also includes a mounting bracket and 1/4–20 thread knob to attach to an ETS-Lindgren tripod or tower adapter. For the variety of mounting options available for the Model 3143B, see Mounting Instructions on page 19.
Tripod Options ETS-Lindgren offers the following non-metallic, non-reflective tripods for use at both indoor and outdoor EMC test sites. For easy horizontal and vertical polarization, the ETS-Lindgren Model 7-TR tripod is recommended. 4-TR Tripod—Constructed of linen phenolic and delrin, designed with an adjustable center post for precise height adjustments. Maximum height is 2.0 m (80.0 in), and minimum height is 94 cm (37.0 in). This tripod can support up to an 11.8 kg (26.0 lb) load.

4.0 Assembly Instructions Before connecting any components, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment.
Attach Bowtie Elements Photos of bowtie elements used in this section may differ from the bowtie elements for your Model 3143B; the assembly procedure is the same for both. The Model 3143B ships with the bowtie elements detached.
1. For stability, mount the Model 3143B onto a tripod or tower. See Mounting Instructions on page 19 for the steps to mount the antenna. 2. Slide the narrow end of one of the bowtie elements into the receptacle hole on the antenna balun, and then align the bowtie with the receptacle on the balun. Do not cross thread this connection or permanent damage to the bowtie element could occur. 3. Insert one of the 10–32 thumbscrew knobs into the opposite side of the balun from where you inserted the bowtie.

5.0 Mounting Instructions Before connecting any components, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. The Model 3143B antenna is a precision measurement device. Handle with care. Contact with any metal or non-metallic structure can capacitively load the antenna, which may cause unrepeatable results.
Using Included Mounting Adapters In addition to the attached mounting bracket and mounting knobs, the Model 3143B ships with these mounting adapters: 100989 Polarizing Mounting Adapter with 7/8–14 thread receptacle If you need to convert the polarizing adapter to a 1/4–20 receptacle, insert the 1/4–20 thread insert into the polarizing adapter 105861 1/4–20 Thread Insert 20 | Mounting Instructions
To attach the included adapters to the Model 3143B: Model 3143B mounted onto 4-TR using included 100989 Polarizing Mounting Adapter and 105861 1/4–20 Thread Insert 1. If required, insert the 1/4–20 thread insert into the mounting adapter. 2. Remove the mounting knob from the mounting bracket on the antenna. 3. Slide the mounting bracket onto the mounting adapter with the adapter placed between the shoulders of the mounting bracket. 4.
Using the Stinger to Mount to a Model 2175 MiniMast Do not use the stinger to mount the Model 3143B 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. Before you begin: Install the center rotate boom (part# 108197) for rear-mount stinger-type antennas.
2. Attach the cable to the Type N connector at the end of the stinger. 3. Slide the cable and stinger into the clamp on the boom, carefully guiding the cable out the other end. 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.
5. Tighten the clamp knobs on the boom to secure the antenna into place.
Additional Mounting Options 4-TR MOUNTING OPTIONS Following are additional options for mounting the Model 3143B onto an ETS-Lindgren 4-TR tripod. Contact the ETS-Lindgren Sales Department for information on ordering optional mounting hardware.
7-TR AND M AST MOUNTING OPTIONS The stinger on the Model 3143B enables you to mount to antenna directly to an ETS-Lindgren 7-TR Tripod Positioner. However, following are additional options for mounting the Model 3143B onto an ETS-Lindgren 7-TR Tripod Positioner. Contact the ETS-Lindgren Sales Department for information on ordering optional mounting hardware.
Mast refers to 2070 Series, 2075, and 2175 Antenna Towers.
2X2 BOOM MOUNTING OPTIONS Following are additional options for mounting the Model 3143B onto a 2x2 boom. Contact the ETS-Lindgren Sales Department for information on ordering optional mounting hardware. 2x2 boom refers to a typical 2-inch by 2-inch boom.
6.0 Typical Data Typical Antenna Factor and Gain 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 bowties, which is about 45 cm from the small end tip.
