Arrays, Signal Transformers: The SRF1280-4R7Y Application Field and Working Principle

The SRF1280-4R7Y (also known as the RF1280-4R7Y) is a high power, reflective array antenna device developed by a leading global antenna manufacturer. It is designed for use in wireless data networks, such as Wi-Fi systems.This device is made up of an array of four transmitting antenna elements, each with two distinct working principles. The first is what is referred to as the directivity principle, which creates directivity by adjusting the power level of each individual element to optimize the signal reception. The second is what is known as the polarization principle, which creates polarization by controlling the angle and tilt of each of the four elements to give the antenna its desired coverage range.In addition to providing the directivity and polarization required to transmit and receive wireless signals, the SRF1280-4R7Y offers two major benefits for wireless systems. The first is its high power output, which can support up to 4 watts transmitter power and up to 50 watts receiver sensitivity. This allows the device to be used in a variety of wireless applications, from short distance communication to long-range data transmission. The second benefit is its compact size and low profile, making it an ideal solution for applications where space is limited, such as rooftops and tight spaces.The SRF1280-4R7Y is designed to be used in a variety of arrays or signal transformers, such as Wi-Fi extenders, repeaters, and signal boosters. Its design also allows the antenna structure to be used as a signal subscriber, which allows the antenna to be used as part of a wireless network. This makes the SRF1280-4R7Y an excellent choice for both commercial and residential applications.In addition, the SRF1280-4R7Y is built with advanced tracking technology, which enables the device to adjust its power level based on nearby transmissions. This ensures that the signal is always optimally received and sent out with minimal interference or noise levels. The signal can also be tracked for up to a five minute window in order to save power and reduce interference from strong signals.The SRF1280-4R7Y also offers a wide variety of features, including weatherproof construction, wide angle beamwidth, automatic gain control, and temperature sensors. This makes the device an ideal choice for outdoor wireless applications, such as surveillance cameras and wireless LANs. The signal can also be tracked in real time, enabling the device to adjust to changing conditions quickly and accurately.Overall, the SRF1280-4R7Y is an ideal solution for a variety of wireless applications, offering high power output, a wide range of features, and a compact size and low profile that make it suitable for even the tightest of spaces. With its advanced tracking technology and weatherproof construction, it is an ideal choice for both commercial and residential applications, as it is able to adjust automatically to changing conditions and optimize reception and transmission of signals with minimal interference.
