ATEC Assurance With Every
The ETS-Lindgren 3109 Biconical 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 the ETS-Lindgren 3109 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. The ETS-Lindgren 3109 is ideal for IEC 1000-4-3 testing.
