Page 7: Introduction
1.0 Introduction The ETS-Lindgren Model 3159C High-Power Biconical Antenna is a broadband, linearly polarized biconical antenna with a 20 MHz to 100 MHz frequency range. This antenna exhibits a wide beamwidth and is designed to handle up to 10 kW input power for generating high electric field strength over a large uniform area. -
Page 8: Ets-Lindgren Product Information Bulletin
Unlike the top hat, capacitive-loaded, log periodic dipole antenna normally used in this frequency range, the phase center/source distance is the same for low and high frequencies. This ensures high field strength at frequencies as low as 20 MHz. The design of the Model 3159C takes advantage of the wide beamwidth feature of a biconical antenna. -
