ANT-418-HETH application field and working principle

The ANT-418-HETH is a high efficiency broadband dual polarization antenna, which is widely used in the field of dual polarization microwave and ultra-wideband radio frequency. This antenna is designed to provide wireless: Multimedia Broadcast, TV broadcasting and digital communication systems access to extremely efficient, wide-ranging coverage, allowing users to send data at higher rates over longer distances. The antenna has two polarized lobes and is designed to provide a higher degree of transmission and reception efficiency indoors and outdoors to fully optimize communications reliability and signal-to-noise ratio. The ANT-418-HETH is also designed to be omnidirectional with full 360° coverage, while maintaining high gain, low cross-polarization, and good impedance match characteristics.This antenna can be used for a range of communication applications, including long-distance communications, backbone data link networks, multimedia broadcast systems, and point-to-point communication networks. The ANT-418-HETH is also capable of providing scaleable coverage for various bandwidth applications, from 5 GHz to 13.25 GHz with a frequency range of 1-40GHz. The antenna offers high gain and directivity to ensure consistent and reliable signal reception and transmission.The ANT-418-HETH antenna is an omnidirectional antenna that provides effective coverage over wide frequency ranges and long distances. It is capable of transmitting power up to 40 watts and offers greater than 20dB gain on all frequencies between 5 to 13.25 GHz. The antenna features high Efficiency, Low Side-lobe Ratio, High Gain, and Low Cost. The antenna also features low voltage standing wave ratio (VSWR) of less than 1.5:1. The antenna also has the ability to detect circularly polarized signals.The ANT-418-HETH works by using a dual-radiate antenna. The two antenna elements each have a 180-degree polarization. The antenna elements also have a symmetrical radiation pattern, which helps in achieving the desired beamwidth for any given application.The ANT-418-HETH is manufactured using a conductive material such as copper or aluminum to ensure its durability and resistance to wear. The antenna is also designed with a high degree of stability and robustness to withstand harsh weather conditions. The ANT-418-HETH is also designed with an integrated hermetically sealed RF feeder line, which helps further secure the antenna from external damage and interference.The ANT-418-HETH antenna offers many advantages for use in radio frequency applications. Its dual polarizations provide great coverage indoors or outdoors and its narrow beam width also helps in providing coverage for smaller areas. Its high gain and wide frequency range make the antenna ideal for point-to-point communication such as long-distance communication. networks, multimedia broadcast systems, and other communications applications. Its high efficiency and low cost make it an ideal low cost option to many communication applications. Finally, its hermetic RF feed line ensures secure performance in harsh weather environments.
