EXD450SFU

RF Antennas

The EXD450SFU antenna is an ideal choice for a variety of applications, due to its highly efficient, wide operating temperature range and low cost design. This antenna is a Radio Frequency (RF) antenna designed to transmit and receive very high frequency (VHF) and ultra high frequency (UHF) signals. It is often used as part of a cellular communication, radio navigation, telemetry, and tracking systems.

Application Field

The EXD450SFU is a medium gain antenna, with a gain of 12 dBd and maximum VSWR of 1.5:1 in the frequency range from 400 MHz to 450 MHz. This type of antenna is widely used in air traffic control, maritime or ground-based navigation systems, paging systems and radio communication for air, marine, and land applications. In addition, it can also be used in Wi-Fi system, terrestrial television, FM radio broadcasting, communication link or data transmission.

Working Principle

The EXD450SFU antenna works by capturing radio waves through a directional design. It is shaped like an array of dipoles with a hyperbolic parabolic reflector mounted behind it. This reflector creates a strong gain in the direction the antenna is pointed to, meaning the signal gains are stronger when compared to an isotropic antenna, whose signal gains are same in all directions. This antenna also can runs on both linear polarization and circular polarization, which makes it suitable for applications like satellite communication.

The antenna’s gain is very important in terms of how far the Wi-Fi or radio signals can travel. As the gain increases, the signal extends further. With high gain, these signals can be extended beyond the line-of-sight, enabling communication over greater distances. The EXD450SFU also provides efficient signal coverage and is a cost-effective, dependable device for a variety of applications where the wireless signal needs to be extended or amplified.

Conclusion

The EXD450SFU antenna is an efficient and cost-effective choice for RF applications. With high gain and wide operating temperature range, it is suitable for a variety of applications like cellular communication, FM radio broadcasting, data transmission, paging systems, and radio navigation. Its robust design ensures it performs well in applications that require long-term reliability.
