ETS-Lindgren 3109
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 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.

Got wonderful experience with Axiom. They have all the devices we need and the lady is very helpful during the usage. I accidentally dropped an important item in the package during equipment return. The lady Geri happened to find it and sent it back! Both great thanks to Geri and their team! -- Kevin H. San Jose, CA |
