Frequency Range: 20 MHz – 300 MHz
The Model 3109 Biconical antenna is ideal for IEC 1000-4-3 testing as it provides both a broad frequency and high input power.
The 3109 uses a modified Guanella balun for impedance transformation and matching, and 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 its performance in this region.
ETS-Lindgren is the only manufacturer to offer optional extended elements. These elements are twice as long as standard elements and enable users to generate high fields at low frequencies with less than 25% of the power usually required.
