Introduction

The TQX-900CI is a type of RF antenna which uses advanced technology to provide excellent signal coverage in a variety of applications. It is an easy-to-install, robust antenna that offers exceptional performance at a reasonable cost. It is highly adaptable to a range of reception conditions, making it suitable for a variety of applications such as home and business wireless networks, wireless broadcasting, and radio astronomy.

TQX-900CI Application Field and Working Principle

Application Field

The TQX-900CI antenna is designed to be used in a variety of applications, including:

• Wide spectrum radio communication
• Broadcast reception
• Navigational aids
• Radio astronomy
• Wireless networks
• Telemetry and remote monitoring

Working Principle

The TQX-900CI is a log-periodic dipole array antenna operating on frequencies from 890 MHz to 30Mhz. It is specifically designed to offer extremely high performance in the 400-900MHz frequency range. This range includes most of the global cellular network standards (GSM, EDGE, WCDMA, etc.), as well as public safety bands.The antenna consists of two dipoles mounted in a log-periodic array, arranged in pairs along a straight line. Each dipole is tuned to a specific frequency, from 890 MHz to 30 MHz. The two dipoles are arranged so that they are exactly 180 degrees out of phase from each other. This arrangement creates a dipole array that is optimized for both the operating frequency and radiation pattern.The TQX-900CI is designed to provide an omni-directional radiation pattern with a gain of up to 6 dBi in the 400-900MHz range. The antenna also offers excellent linear polarization. This type of antenna is often used to minimize multipath interference, as it is highly effective at cancelling out signals coming from multiple directions.The antenna also utilizes a unique construction that makes it lightweight and resistant to hardware damage. The aluminum reflector elements are corrosion resistant and designed to minimize the impact of wind loading. The dipoles are made of high-grade stainless steel, ensuring that they will last for years in the harshest environments.

Conclusion

The TQX-900CI antenna is an excellent choice for a wide range of applications, from wireless networks to radio astronomy. The unique log-periodic dipole array design provides excellent reception over a wide range of frequencies, with a gain of up to 6 dBi. The antenna is lightweight, easy-to-install, and highly resistant to damage, making it suitable for use in any environment.
