ETS-Lindgren's Model 3149 Hybrid Log Periodic and Bowtie (BiConiLog) Antenna has an ultra broadband frequency range, accepts high power input, and is size-efficient for easy transport and use in compact chambers. Rugged construction assures dimensional and electrical stability over extended use. The electrical characteristics of this antenna were modeled using powerful workstations running electromagnetic simulation software. Equally important, experienced RF engineers worked with our manufacturing team to produce a practical and affordable realization of the modeling process. On completion, the antenna was tested and calibrated at our A2LA accredited lab facility. All production units are individually calibrated at this facility.
