An essential component of any radio communication system, RF antennas are the physical connection between radio transmitters and receivers and the outside world. The antenna provides the link for the transmission of electrical signals over large distances. Among the array of antenna designs, the FG8243 has become popular for its features and operational benefits. This article will discuss the application field and working principle of the FG8243.

What is the FG8243?

The FG8243 is a type of dual-linear polarized, omni-directional antenna used in radio communication systems. Developed in the late 1980s, it became a major part of most modern communication systems. Thanks to its part-pendent arc design, this antenna is able to accommodate two separate linear polarizations and provide an output with high horizontal and vertical radiation characteristics.

Applications of the FG8243

The FG8243 is most widely used in wireless LAN systems, such as IEEE 802.11a and 802.11b. These systems are now commonplace in homes, offices, and restaurants. The FG8243 is also used for point-to-point directional communications and has been found to be a great antenna for satellite communications. Additionally, the FG8243 is used in military communications systems, such as long-range aircraft. This provides excellent reception at both long and short distances.

Working Principle of the FG8243

The FG8243 works together with a duplexer and an amplifier. The duplexer is connected to the radio transmitter and receiver, allowing them to communicate while using only one antenna. The amp is used to boost signal levels. The antenna’s design features a dipole element for each of the two linear polarizations.

The two dipoles are arranged in a pendent arc pattern in order to avoid interaction between the two signals. In addition, the antenna’s height helps reduce interference and noise. Lastly, the FG8243 features an efficient match, allowing it to transfer more power to the transmitter than other antenna designs.

Conclusion

The FG8243 is an omni-directional, dual-linear polarized antenna used in a variety of radio communication systems. It works together with a duplexer and an amplifier to boost signal levels. Its part-pendent arc design provides a highly efficient match and excellent horizontal and vertical radiation characteristics, making it a great choice for many applications, such as wireless LANs, point-to-point directional communications, and military communications.
