WebbIts gain and beam shape is decided by the turn numbers of the helixes. It is easier to get shaped beam with more helix turns, whereas the reliability of the structure need be considered with more turns. The turn number of each helix is chosen as 4 in this case. The antenna is omni-directional in the azimuth plane and is shaped with conical http://www.ichacha.net/beam%20shape.html
