In telecommunication, a collinear antenna array is an array of dipole antennas mounted in such a manner that every element of each antenna is in an extension, with respect to its long axis, of its counterparts in the other antennas in the array. Telecommunication is the extension of communication over a distance. ... In computer programming, an array, also known as a vector or list, is one of the simplest data structures. ... A yagi antenna Most simply, an antenna is an electronic component designed to send or receive radio waves. ...

Note: A collinear array is usually mounted vertically, in order to increase overall gain and directivity in the horizontal direction. When stacking dipole antennas in such a fashion, doubling their number will, with proper phasing, produce a 3 dB increase in directive gain. Electronics In electronics, gain is usually taken to meaning the ratio of the signal output of a system to the signal input of the system. ... Phasing describes relative phase shift in superposing waves. ... Although it is widely used as a measure of the loudness of sound, the decibel is more generally a measure of the ratio between two quantities, and can be used to express a wide variety of measurements in acoustics and electronics. ... In telecommunication, the term directive gain has the following meanings: 1. ...
