3159C Biconical Antenna

3159C Biconical Antenna

Frequency Range: 30 MHz – 100 MHz ETS-Lindgren's Model 3159C Biconical Antenna is a broadband, linearly-polarized biconical antenna which exhibits a wide beamwidth and is specially designed to handle up to 10 kW input power for generating high electric field strength over a large uniform area. An optional wheeled pedestal is available which permits horizontal and vertical antenna polarization, height, and tilt angle adjustments. A pneumatic cylinder is used to change polarization, and can be remotely controlled using an optional Model 2090 Controller. The Model 2090 is IEEE-488 compatible, and uses fiber optic I/O for communication with the pedestal. Unlike a top-hat capacitively-loaded log periodic dipole antenna normally used in this frequency range, the phase centre/ 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 3159C Biconical Antenna takes advantage of the wide beamwidth feature of a biconical antenna, and its optimized design provides low VSWR and high radiation efficiency.
