ETS-Lindgren 3186 is a Dual Stacked Log Periodic Dipole Array (LPDA) antenna. It is ideal as a receive antenna for CISPR 16-based testing above 1 GHz. It covers a frequency range of 1 GHz to 18 GHz and provides increased gain when compared to a single LPDA. The beamwidth in the two principal planes is 59.8 degrees for the E-plane and 57.0 degrees for the H-plane, while the directivity is about 10 dB across the entire frequency range. The antenna has a 50 Ω input impedance and includes a stinger mount and standard 1/4–20 thread mounting hardware.
