EST 3142B Log-Periodic Dipole Array (LPDA) Antenna

The Model 3142B Log-Periodic Dipole Array (LPDA) Antenna is specifically designed for making CISPR 16-1 measurements using an engineering and manufacturing process that offsets all its elements in a precision pattern. The 3142D also has excellent cross-polarization that ensures minimum measurement uncertainty for radiated emissions and normalized site attenuation measurement, as well as relatively constant linear gain in the far field. Its precision construction and assembly result in excellent VSWR and optimal phase relationships.
