Frequency Range: 200 MHz – 5 GHz

The Model 3147 is primarily designed for use with the FCC Part 15, Subpart A, Section 15.33. This model covers both the traditional (200 MHz to 1 GHz) and newer (1 GHz to 5 GHz) frequency range requirements in a single unit.

The frequency ratio of 25:1 is one of the widest responses obtainable in a commercially available EMC test antenna. In addition, the Model 3147 has excellent VSWR characteristics throughout the entire operating frequency range.

ETS-Lindgren log periodic antennas are constructed of lightweight, corrosion-resistant aluminium, providing years of trouble-free indoor and outdoor service. Precision construction and assembly of the boom and elements result in excellent VSWR and optimal phase relationship. These antennas feature relatively constant linear gain (measured in the far field) without any sudden “dips” or “bumps”.
