ETS-Lindgren 3159 Biconical Antenna - Manual (Page 8)

8 | Introduction
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
30 MHz. The design of the Model 3159 takes advantage of the wide beamwidth
feature of a biconical antenna. In addition, the optimized design provides
low VSWR and high radiation efficiency.
