  • ETS-Lindgren's Model 3186 is a dual stacked log periodic dipole array antenna (LPDA), each of the two separate LPDAs comprising the dual array are 100 antennas. When assembled in parallel, the results are a 50 input impedance array. This array provides increased gain when compared to a single LPDA. The arrangement of the two LPDA in the arrays provides a very constant pattern across the entire frequency range.

    This antenna is ideal as a receive antenna for CISPR emissions testing above 1 GHz. It is also ideal when performing the site VSWR test as per CISPR 16.
