Working Principle

The W4120GL5000 antenna utilizes a dipole array design with horizontally polarized probes. This design provides an exceptionally broad bandwidth and high levels of gain and efficiency. The antenna uses an internal radome for protection from the elements, and also houses all other components needed for proper operation. The antenna is connected to the transmitter via a coaxial cable, with two wires used to pass the signals between the two components.

The signals from the transmitter are applied to the antenna element, which then radiates them in a specific direction with a specific polarization pattern. This is achieved through several techniques, one of which is the use of parasitic elements such as director and reflectors which act to “shape” the radiated signal. The director elements are typically short, and are generally placed in front of the radiator, while the reflectors are longer and placed behind the radiator.

The antenna is designed for high gain, and is able to produce a gain of up to 9 dBi. This gain is achieved through the use of the director and reflector elements, which direct and “shape” the radiating signal, as well as through the use of other technology such as matching networks which improve the impedance match between the antenna and the transmitter. The antenna is also able to provide an exceptional degree of selectivity by rejecting unwanted frequencies.
