6.0 Application
The Model 3109 Biconical Antenna provides a broad frequency and a high input
power, making it ideal for IEC 61000-4-3 testing. The antenna uses a modified
Guanella balun for impedance transformation and matching, and it is constructed
of much heavier materials so that maximum continuous input power can reach
2 kW. While this antenna typically has a high VSWR at frequencies below
70 MHz, it is still capable of generating a high field strength with acceptable input
power in this region of the band. The optional extended elements markedly
improve performance in this region.
