  • ETS-Lindgren's Model 3147 Log Periodic Dipole Array is primarily designed for use with the FCC Part 15. The Model 3147 has excellent VSWR characteristics throughout the entire operating frequency range and has a relatively constant linear gain (measured in the far field).

    This antenna is constructed of precision, corrosion-resistant nickel-plated brass tubing, for years of trouble-free indoor and outdoor use. In addition to the excellent VSWR, precision construction and assembly of the boom also results in an optimal phase relationship.
