ETS-Lindgren 3148B Log Periodic Dipole Antenna 200 MHz – 2 GHz

Description

The ETS-Lindgren Model 3148B Log Periodic Antenna is specifically designed for making CISPR 16-1 measurements which require a 20 dB difference in the cross polarization rejection. This is achieved using an engineering design and manufacturing process that offsets all of the elements in a precision pattern. The excellent cross-polarization property ensures minimum measurement uncertainty for radiated emissions and normalized site attenuation measurement.

The precision construction of the assembly of the boom and elements result in excellent VSWR and optimal phase relationship.

The Model 3148B antenna features relatively constant linear gain (measures in far field without any sudden dips or bumps).

A Type N connector is provided.

Frequency Range
The frequency range of the Model 3148B is 200 MHz to 2 GHz. This makes the Model 3148B ideal for CISPR 16 testing and other standards based on it, such as CISPR 25.

High Gain
The Model 3148Bs design provides a balance between the shortest antenna and the highest possible gain, with a 5 dB average gain over its frequency.

Low VSWR
The choice of spacing between booms and the changing element diameter provide excellent impedance of the antenna. This results in a in low VSWR.

Individually Calibrated
The Model 3148B is individually calibrated at 1 m per SAE ARP 958 and 3 m and 10 m per ANSI C63.5. This antenna also comes with a signed Certificate of Calibration Conformance.

Flexible Mounting System
The Model 3148B antenna includes both an EMCO classic mount and a rear "stinger" mount.
