​ETS-Lindgren's Model 3140B BiConiLog is one in a series of hybrid antennas designed for broadband EMC radiated immunity (RI) measurements. The model 3140B BiConiLog features a patented T-Bow Tie element design that significantly improves low frequency performance, compared to conventional biconical or other hybrid antennas. When setting up the model 3140B, the T-Bow Tie elements are easily attached/detached with hand tightened screw knobs. Once assembled, the antenna is self-standing when placed balun end down on the ground plane. A tough powder coat finish protects the antenna.                       

The Model 3140B BiConiLog is not designed to be used for RE (radiated emissions) measurements. For RE applications, ETS-Lindgren recommends the model 3142E Biconilog.
