RF accessories are an incredibly wide-ranging class of radio frequency equipment designed to facilitate communication between two or more devices. The MB195NFI is one of many examples of highly specialized RF accessories that exist to meet the needs of various applications. In this article, we shall explore the application fields and working principles of the MB195NFI.

Application Fields

The MB195NFI has a range of applications that include the broadcasting, cellular, wireless data, and land mobile industries. It is used as a base station equipment for direction finding, or DF, along with many other functions. The MB195NFI is a complete DF system that utilizes high power wideband directional antennas to achieve precision areas of coverage.

These antennas are capable of providing a near 360° coverage angle and are calibrated and tested with a very low resistance from circuit to the antenna ground. The antenna can also be effectively used in ranges from 40MHZ to 950MHz, making it one of the most versatile and effective directional antennas that can cover a wide range of frequencies.

Working Principle

The MB195NFI uses an adjustable circular polarization technique, which can provide attenuation up to 30 dB across the full range of frequencies. The MB195NFI system also features an Electronic Phase Shifter (EPS) that can be used to shape the polarization of the antennas signals to increase or decrease the directivity of the antennas. The EPS allows the antennas to be used in any configuration in order to achieve the required coverage.

It is important to note that the MB195NFI is a self-calibrating system, meaning that the antennas may be used in any location without having to be re-calibrated. This feature helps decrease the overall setup time and makes it an ideal accessory for installation on a variety of platforms.

Other features of the MB195NFI include its ability to operate remotely, making it possible to adjust the antennas remotely to optimize the coverage area. This feature is especially useful for installations in hard to reach areas. The MB195NFI system also features a built-in power supply that eliminates the need for an external power source.

In conclusion, the MB195NFI is a specialized RF accessory that is designed for the broadcasting, cellular, wireless data, and land mobile industries and offers adjustable circular polarization along with a range of other features. Its flexibility and ease of use make the MB195NFI an ideal choice for many applications.
