13.2.2 Collinear Array Antennas

A collinear array antenna is typically composed of several linear antennas
stacked on top of each other. The more stacked elements it has, the longer it is,
and the more gain it has. The signal is connected at one end.

The antenna pattern is torroidal. Its azimuthal beamwidth is 360°
(omnidirectional). Its vertical beamwidth depends on the number of
elements/length, and more elements produce a narrower beamwidth.

The antenna gain depends on the number of elements/length, and more
elements produce a higher gain. The typical gain for this antenna is 5 to 10
dBi.

The antenna polarity is linear, or parallel to the length of the antenna.
