1.0 Introduction The ETS-Lindgren family of Double-Ridged Waveguide Horn Antennas consists of linearly polarized broadband antennas ranging in frequency from 100 MHz to 40 GHz. These antennas were designed and built specifically from EMI measurements and specifications compliance testing. However, they can also be used for antenna gain, pattern measurement, surveillance, automotive, and military EMC immunity applications.
MODEL 3119 The Model 3119 Double-Ridged Waveguide Horn is a linearly polarized broadband antenna covering the frequency range of 400 MHz to 6 GHz. The Model 3119 is ideally suited for immunity over 1 GHz and as a reference antenna for wireless testing. In addition, the 3119 is useful for antenna pattern measurement as a source antenna. MODEL 3115 The Model 3115 Double-Ridged Waveguide Horn is a linearly polarized broadband antenna covering the frequency range of 750 MHz to 18 GHz.
MODEL 3116C The Model 3116C Double-Ridged Waveguide Horn is a linearly polarized broadband antenna covering the frequency range 10 GHz to 40 GHz. It is designed and built specifically for emissions and susceptibility testing. The Model 3116C is precision-machined from aluminum. A 50 Ω Type K (2.92 mm) female connector is mounted on the base block of the antenna for increased performance at high frequencies.
7-TR Tripod—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: 2.17 m (85.8 in) Minimum Height: 0.8 m (31.8 in) Maximum Load: 13.
MODEL 3112 POSITIONING SYSTEM The Model 3112 features an option for a fixed height pneumatic-assisted polarization positioning system. The position system is ideal when using the Model 3112 for immunity testing. Power Supply: 160 mA 120 VAC Optional 220 VAC available Pneumatic Interface: 50–80 PSI Weight: 181.43–226.76 kg 400–500 lb Maximum Height: 355.6 cm 140 in Maximum Load: 194.13 cm 76.

4.0 Mounting Instructions Before connecting any components or operating the Double-Ridged Waveguide Horn Antennas, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. The Double-Ridged Waveguide Horn Antennas are precision instruments. Handle with care. Make sure that no part of the antenna is in contact with the tripod or tower.
ATTACH MOUNTING BRACKET TO ANTENNA The Model 3117 Model and 3116C include a stinger mount for centerline rotation measurements; see page 21 for more information. The following illustration represents a typical assembly of the mounting bracket to an antenna. The Model 3116C is shown; however, the steps are similar for each of the Double-Ridged Waveguide Horn Antennas. 1.
ATTACH STINGER MOUNT (MODELS 3117 AND 3116C ONLY) The Model 3117 Model and 3116C include a stinger mount for centerline rotation measurements. 1. Hold the antenna with the connector pointing to the floor and align the holes on the back of the antenna with the ones on the bracket provided. 2. Select set of holes for horizontal or vertical polarization as desired. 3. Insert both thumbscrews and tighten. 4. Align the stinger with the threaded mounting stud then tighten.
MOUNT ANTENNA AND BRACKET TO 4-TR 1. Attach the mounting bracket to the 4-TR by aligning the 1/4–20 connector on the bracket with the 1/4–20 bolt on the tripod. Support the antenna securely while turning the mounting bracket to tighten the connection. 2. To change polarization, support the antenna securely and remove the thumbscrews. Turn the antenna to align the holes on the mounting bracket with the desired set of holes on the back of the antenna. Re-insert the thumbscrews and tighten.
7-TR and Mast Mounting Options Due to the size of the Model 3112, do not mount it onto a 7-TR. For a list of 7-TR boom options, see page 10. For 7-TR mounting instructions, see the 7-TR manual. For instructions to mount a Model 3106B to a 7-TR, see page 29. The stinger on the Model 3117 and Model 3116C enables you to mount the antenna directly to an ETS-Lindgren 7-TR without additional hardware.
2x2 Boom Mounting Options 2x2 boom refers to a typical 2-inch by 2-inch boom. Following are options for mounting a Double-Ridged Waveguide Horn Antenna onto a 2x2 boom. Contact the ETS-Lindgren Sales Department for information on ordering optional mounting hardware.
5.0 Mounting a Model 3112 to the Optional Positioning System Before connecting any components or operating the Double-Ridged Waveguide Horn Antennas, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. Failure to provide continuous support of the antenna when attaching or removing the antenna from the positioning system may result in damage and/or personal injury.
| Mounting a Model 3112 to the Optional Positioning System
Connecting the Optional Positioning System Once the Model 3112 is securely mounted on the positioner, loosen the nuts and turn the wheel at the base of the horn support for better field uniformity. This bore sights the horn 10 degrees. Input Locations Do not connect power to the positioner until the antenna is securely mounted and all connections have been made. The input panel is located on the base of the Model 3112 positioner.
Air Polarization Option Plug the ends of the twin air hoses into the two AIR OUT connectors located on the interface box at the base of the custom positioning system. Plug the opposite ends of the twin hoses into the two 90 degree fittings on the air cylinder of the custom positioning system. Plug one end of the single air hose into the AIR IN connector located on the opposite side of the interface box at the base of the custom positioning system (shown in previous diagram).
6.0 Mounting a Model 3106 Series Antenna to a 7-TR Before connecting any components or operating the Double-Ridged Waveguide Horn Antennas, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. You will need assistance from two team members to mount a Model 3106 Series antenna to the 7-TR. You must install the 108507 boom onto the 7-TR before performing these steps. For clarity, the following illustrations do not show the 7-TR.
Step 2 Lift the mount adapter up and away from the boom. Step 3 Remove the wingnut to free the 1/4–20 screw from the mount adapter. You will re-use the screw in Step 6. 30 | Step 4 Remove the nuts to free the two screws from the vertical plate on the mount adapter. You will re-use the screws in Step 6.
Step 5 On the side of the Model 3106B with the antenna connector, remove the two screws from the mount plate. Retain these two screws for future use; if you remove the Model 3106B from the 7-TR, you will need to replace these screws to provide support for the inner ridge of the antenna. Step 6 Attach mount adapter to the Model 3106B: Using the two screws removed in Step 4, insert the screws through the lip on the vertical part of the mount adapter and into the two holes on the antenna.
Step 7 Attach the mounted assembly to the boom: Use the two 104136 knobs removed in Step 1 to attach the antenna and mount adapter assembly to the boom. Tighten to secure.
