ETS-Lindgren 3180B Broadband Mini-Bicon Antenna - Manual (Page 8)

8 | Introduction
The Model 3180B is designed to have a radiation pattern that is omni-directional
in the H-plane and maintains a single lobe in the E-plane across the range. The
elements have been optimized to avoid splitting of the main radiation beam in the
elevation cut.
The Model 3180B includes a stinger mount and standard mounting hardware.
For the variety of mounting options available for the Model 3180B, see
Mounting Instructions on page 23.
