FM2LB

FM2LB application field and working principle

FM2LB is an RF accessory that is usually used with a base station antenna. It is commonly used to increase the signal gain of a base station antenna in order to improve its performance. The FM2LB is typically used in the context of directional antennas with ranges of up to a few kilometers to enhance the radio frequency (RF) signal quality and range. It is often deployed in digital radio environments, such as in cellular networks, as it provides a good increase in RF signal strength over the distances a base station may cover.

The FM2LB antenna accessory consists of two dipole antenna elements that are mounted approximately perpendicular to each other. The dipole antenna elements also contain radiators that allow for the correct impedance and radiation pattern as well as the increased signal strength gain. The FM2LB antenna accessory has a working frequency range from 450 MHz to 1000 MHz, and it is said to provide a gain of up to 15 dB. The FM2LB application area is normally limited to cell range coverage, as this accessory is not designed to cover larger areas.

To set the FM2LB antenna accessory up, the antenna needs to be pointed in the correct direction in order to focus the signal gain in the desired area. The radiated gain then contributes to an increased efficiency in the transfer of information within the desired range and allows for increased reliability of the system. The radiation pattern of the system can also be adjusted by adjusting the phase lag between the two dipole elements of the antenna.

The work of the FM2LB antenna accessory includes both the transmission and reception parameters. During the transmission, the antenna radiates RF energy to the desired area, allowing the wireless signal to reach its user successfully and accurately. During reception, the FM2LB antenna accessory adds to the incoming signal, therefore enhancing the signal reception and noise rejection, leading to more accurate and reliable transmissions.

The FM2LB antenna accessory is a cost-effective and easy way to increase the signal range of a base station antenna, especially in digital radio environments. With its increased signal gain, the FM2LB antenna accessory also helps reduce interference and allows more accurate signal reception over the distances a base station is designed to cover. The FM2LB is able to reach its full potential when paired with a solid reflector or parabolic antenna, providing a strong and reliable signal for the intended area.
