Antenna Characteristics
Antennas have three main characteristics:
horizontal coverage pattern
(horizontal beamwidth)
vertical coverage pattern
(vertical beamwidth)
gain
(signal amplification power)
3.1.1 Antenna Coverage Patterns
Antennas transmit and receive signals in a specific pattern; each pattern has a horizontal and vertical
component. (See Figure 2.)
component. (See Figure 2.)
