RF Antennas are antennas used for the transmission and reception of radio frequency signals. They are essential in wireless technology in order for the signals to be transmitted, received and amplified. The YDA4704 or BA4704 is a type of RF Antenna. It is a directional antenna designed for a specific frequency range, making it an ideal antenna solution for a variety of applications.

YDA4704 Applications

The YDA4704 is a medium-sized directional UHF antenna designed to operate in the 400 to 500 MHz frequency range. It can be used for base station applications as well as for fixed-site systems and vehicular systems. It can be used for any application that needs a directional UHF antenna such as monitoring and surveillance, fixed wireless services, point-to-point and point-multipoint networks, radio communication as well as satellite communications.

The YDA4704 is known for its excellent electrical performance, with good gain, high efficiency, robust design, low noise figure, and wide bandwidth. It is also rain and wind tolerant, making it an ideal solution for outdoor applications.

YDA4704 Working Principle

The YDA4704 works based on the principle of resonance. It works by collecting a small portion of the electromagnetic energy that passes through it and resonating it in a specific direction. This is achieved using its metal elements that are arranged in a specific pattern, called an array.

The elements are arranged in such a way that they form an array antenna. Each individual element picks up a small portion of the total energy and resonates in a specific direction. The combination of all the individual elements results in a high level of radiation in the desired direction.

The YDA4704 also has the ability to amplify the signals it receives, increasing the signal strength and providing improved reception for the desired direction. This feature is especially useful for long-distance and outdoor applications. The antenna is also able to identify which direction the signal is coming from, allowing it to be pointed in the right direction.

Conclusion

The YDA4704 is a directional UHF antenna designed to operate in the 400-500 MHz frequency range. It is an ideal antenna solution for a variety of applications such as monitoring and surveillance, base station applications, point-to-point and point-multipoint networks, radio communication, and satellite communications. It works based on the principle of resonance, using its metal elements to collect and resonate a small amount of the electromagnetic energy that passes through it while amplifying the signal in the desired direction. With its excellent electrical performance, robust design, low noise figure and wide bandwidth, the YDA4704 is an excellent choice for long-distance and outdoor applications.
