CB Antenna Beam-forming
Beam antennas use a technique known as beam-forming for signal transmitting and/or receiving. Beam-forming takes a signal and guides the direction that it goes. Beam-forming is often used in RF broadcast such as CB Radio, TV and FM radio, amateur (ham) radio, and on cell phone towers.
The side of the beam antenna with the smaller elements, the directors, is considered the front of the beam-aerial, while the side with the longer elements, the reflectors, is the back. To CB receive a signal, the antenna is pointed in the direction of the signal, and the smaller elements pull the signal into the middle CB beam element. The longer CB beam elements reflect back any radio signal that would be lost back to the center element.
An important characteristic of any multi-antenna configuration is the distance between the different antenna elements, to a large extent because of the relation between the distance and the mutual correlation between the radio-channel fading experienced by the signals at the different antennas.
The antennas in a multi-antenna configuration can be located relatively far from each other, typically implying a relatively low mutual correlation. Alternatively, the antennas can be located relatively close to each other, typically implying a high mutual fading correlation, that is, the different antennas experience the same, or at least very similar, instantaneous fading.
