Introduction | 7

1.0 Introduction

The ETS-Lindgren Model 3182 Broadband Biconical Antenna is designed for

optimal performance across the frequency range of 30 MHz to 1 GHz. The

uniquely-designed elements provide an omni-directional pattern without the main

radiation beam splitting into two lobes in the elevation cut.

In addition to covering the traditional frequency range EMC measurements, the

Model 3182 covers all the VHF and part of the UHF bands, making it ideal for

spectrum monitoring of FM, TV, and some cellular phones.

The Model 3182 is designed to have a radiation pattern that is dipole-like across

the range. The elements have been optimized to avoid any splitting of the main

radiation beam in the elevation cut.

The Model 3182 is ideal for surveillance and spectrum monitoring. The

omni-directional patterns can receive signal from every direction in the azimuth.

The Model 3182 includes a stinger mount and standard mounting hardware. For

the variety of mounting options available for the Model 3182, see
Mounting Instructions on page 17.

Tripod Options

ETS-Lindgren offers the following nonmetallic, non-reflective tripods for use at

both indoor and outdoor EMC test sites.

• Model 4-TR—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.

• 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. Maximum height is

2.17 m (85.8 in), with a minimum

height of .8 m (31.8 in). This tripod

can support a 13.5 kg (30 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.

The Model 3182 Broadband Biconical Antenna is shipped unassembled, and

includes these parts:

• Balun – includes attached stinger mount

• Biconical element (2)

• Belleville washer (2)

• Clamp block

• Support rod and base

16 | Assembly Instructions

To assemble the Model 3182:

1. Slide a belleville washer onto the threaded screw end of one of the

biconical elements.

2. Line up the screw threads with the receptacle hole on the balun and

turn the biconical element until it is firmly secured in the balun.

Do not cross thread this connection or
permanent damage to the joint could occur.

3. Repeat step 1 and step 2 using the remaining washer and biconical

element.

safety information in the ETS-Lindgren
Product Information Bulletin included with your
shipment.

Using Included Mounting Adapters

The Model 3180 Mini-Bicon Antenna ships with these mounting adapters, used to

mount the antenna to a 4-TR tripod:

• 102108 Clamp Block—Uses

standard 7/8–14 threads and comes

with a 1/4–20 thread adapter for

mounting to an ETS-Lindgren tripod

or most other tripods.

• 100733 Support Rod

• 101942B Support Base

18 | Mounting Instructions

To use these adapters to mount the Model 3182 to a 4-TR tripod:

Shown mounted with clamp block and support rod

(support base not shown)

1. Assemble the clamp block, support base, and support rod, and attach

the support base to the 4-TR tripod.

2. Unscrew the clamp block latch and open the top.

3. Insert the balun into the clamp block and close the top over the balun.

4. Move the latch to the closed position and tighten so the balun is held

securely.

5. Attach the cable to the output connector on the antenna.

Application | 23

6.0 Application

The Model 3182 Broadband Biconical Antenna is ideally suited for swept site

attenuation measurements per ANSI and FCC specifications. The Model 3182

can be used for horizontal and as vertical site attenuation measurements. A

20 dB pre-amplifier is recommended in line with the receive antenna to minimize

the required transmitted power and to reduce the possibility of saturation of the

transmitting antenna. The maximum continuous input power to the Model 3182 is

250 mW.

When the Model 3182 is used vertically, the same element orientation need not

be maintained from measurement to measurement. The Model 3182 exhibits

excellent symmetrical performance, and test repeatability is assured by the balun

design.

Each antenna is calibrated during manufacturing. The results of the calibration

are tabulated as gain and antenna factor vs. frequency for use in Specification

Compliance Testing. Typical data for the Model 3182 is provided in the next

section.
