SEPTEMBER 2002 1 REV E PN 399034 INTRODUCTION The ETS-Lindgren Model 3104C Biconical Antenna is designed to

7、operate over the 20 to 200 MHz frequency range to meet Military and DOD EMI specifications. It is of lightweight construction for ease in handling and storage. The biconical elements are made from welded aluminum. The elements mount in a balun network which is fabricated of phenolic and is equipped

8、with the necessary impedance-matching components. The Model 3104C is designed and precisely manufactured to conform to the requirements of MIL-STD-461 and other Military Standards as reflected in Drawing ES-F-201286. Each antenna is individually calibrated during the manufacturing process. The resul

9、ts of these calibrations are tabulated and included with the antenna as gain and antenna factor vs. frequency data for use in specification compliance testing. Standard Configuration MODEL 3104C BICONICAL ANTENNA 2 EMC TEST SYSTEMS, L.P. SEPTEMBER 2002 REV E PN 399034 STANDARD CONFIGURATION Antenna

10、Elements Balun Clamp Block Individually calibrated at 1 m per SAE ARP 958 and 3 and 10m per ANSI C63.5. Actual factors and a signed Certificate of Calibration Conformance included. OPTIONS Portable Elements (P): Collapsible folding elements are available, making the antennas portable and ideal for f

11、ield use. Both the standard rigid and optional folding elements attach to the balun using screw mounts. This makes interchanging between the elements very quick and easy. Optional carrying cases are available to further enhance portability. Extended Portable Elements (XP): An extended version of the

12、 portable elements is available. These folding elements are twice as long as the standard elements. The longer elements enable you to generate high fields at low frequencies with reduced applied power. Carrying Cases: Carrying cases for portable elements and biconical antenna are readily available.

13、Support Rod: Antenna mount with insert designed to accept ETS-Lindgren or other tripod with ” x 20 threads Tripods: ETS-Lindgren offers two nonmetallic, non-reflective tripods for use at both indoor and outdoor EMC test sites. The Model 4-TR, constructed of linen phenolic and delrin, is designed wit

14、h an adjustable center post for precise height adjustments. Maximum height for the 4-TR is 2.0 m (80.0 in), while minimum height is 94 cm (37.0 in). This tripod can support up to an 11.8 kg (26.0 lb) load. MODEL 3104C BICONICAL ANTENNA Options EMC TEST SYSTEMS, L.P. SEPTEMBER 2002 3 REV E PN 399034

15、The 7-TR tripod has several different configurations, including options for manual or pneumatic polarization. This tripod provides increased stability for physically large antennas. Its unique design allows for quick assembly/disassembly and convenient storage. Quick height adjustment and locking wh

16、eels provide ease of use during testing. This tripod can support up to a 13.5 kg (30.0 lb) load. For the 7-TR series, maximum height is 2.17 m (85.8 in), with a minimum height of 0.8 m (31.8 in). The 7-TR is constructed of PVC and fiberglass components. Assembly Instructions MODEL 3104C BICONICAL AN

17、TENNA 4 EMC TEST SYSTEMS, L.P. SEPTEMBER 2002 REV E PN 399034 ASSEMBLY INSTRUCTIONS The Model 3104C consists of the following (shipped unassembled): 1 ea. Balun 2 ea. Biconical Elements 2 ea. Bellville Washers (In a small plastic bag) 1 ea. Mounting Clamp Step 1. After carefully unpacking all of the

18、 components, take one of the Bellville washers and slide it onto the threaded screw end of one of the biconical elements. Step2. 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. Be careful not to cross-thread this

19、 connection or permanent damage to the joint could occur. Step 3. Repeat steps 1 and 2 with the other washer and biconical element. Now you are ready to mount the antenna on a tripod for testing.

20、NTENNA Mounting Instructions EMC TEST SYSTEMS, L.P. SEPTEMBER 2002 5 REV E PN 399034 MOUNTING INSTRUCTIONS The mounting clamp of the Model 3104C uses standard 7/8x14 threads and comes with a 1/4x20 thread adapter for versatility when mounting on an ETS-Lindgren tripod or most other tripods for suppo

21、rt. After the mounting clamp is attached to a tripod, unscrew the latch and open the clamp. Insert the balun of the Model 3104C into the clamp and close the top over the balun. Move the screw latch to the closed position and tighten, so the balun is held securely. The cable can now be attached to th

22、e output connector. OPERATION The Model 3104C biconical antenna has a traditional coaxial wound balun which provides a broad frequency range and moderate gain for both transmitting and receiving. This antenna may be used for radiated immunity measurements provided that the peak input power is limite

23、d to no more than 100 W. For enhanced measurement repeatability it is recommended that when the Model 3104C is used vertically the same element orientation be maintained from measurement to measurement. A white strip or dimples on the element block mark the coax shield side of the element. Keeping t

24、his side towards ground when the antenna is used vertically will increase test repeatability especially when the Model 3104C is used inside a shielded enclosure.
