Biconical Model 3104C Features: ●
●
Ideal for Emissions Testing Unique Element Design Improves Performance
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. Model 3104C may be used for radiating immunity measurements provided that the input power is limited to no more than 100 W peak.
Standard Configuration ● ● ● ● ●
Antenna elements Balun Support rod and base Support rod base is drilled to accept tripod mount with 1/4 x 20 threads Individually calibrated at 1 m per SAE ARP 958 and 3 and 10 m per ANSI c63.5. Actual factors and a signed Certificate of Calibration Conformance included in Manual
Options Portable Elements (P) (Part # 101946B) Collapsible folding elements are available for all biconicals making the antennas portable and ideal for field use. Both the standard rigid and optional folding elements attach to the balun using screw mounts. This makes interchanging between the two types of elements very easy and quick. Optional carrying cases are available to further enhance portability. Extended Portable Elements (XP) (Part # 103032B) An extended version of the portable elements is available for all models. These folding elements are twice as long as the standard elements. The longer elements enable you to generate fields at low frequencies with less than 25% of the power usually required. These elements are most effective with models 3104C and 3109. Carrying Cases for Portable Models Carrying cases for portable elements and biconical antennas are readily available.
