Introduction：
The ETS 3144 Log Periodic Dipole Array (LPDA) antenna, manufactured by ETS-LINDGREN in the U.S.A. and authorized to be distributed by EUTTEST in Shenzhen, China, is a standard medium gain (6 dBi) log periodic dipole array. This logarithmic antenna allows the user to scan frequencies from 80 MHz to 2 GHz in one pass, eliminating the need to replace the antenna in the event of a band break, saving time and money.
In addition, the high power input capacity of the ETS 3144 is ideally suited for IEC 61000-4-3 testing and applications that require field strengths in excess of 100 V/m to be generated. The antenna has a hard powder-coated surface that resists scratches and abrasions better than painted or bare surfaces. The ETS 3144 is calibrated to 1 m according to SAE ARP 958 and 3 m and 10 m according to ANSI C63.5, respectively.The antenna also comes with a signed certificate of compliance with the calibration.
