6GK5793-8DJ00-0AA0 ANT793-8DJ IWLAN Antenna Siemens

Product Introduction

The 6GK5793-8DJ00-0AA0 ANT793-8DJ is a professional-grade IWLAN antenna engineered for demanding industrial wireless networks. This antenna operates exclusively in the 5 GHz band, covering frequencies from 5.15 to 5.875 GHz. It delivers an exceptional gain of 18 dBi, making it ideal for point-to-point and point-to-multipoint connections over long distances. Furthermore, its dual-linear polarization (vertical and horizontal) ensures robust signal reception in diverse environmental conditions. Additionally, the antenna features a narrow beamwidth of just 17 degrees in both planes, providing strong directivity that minimizes interference from adjacent networks. Consequently, this antenna excels in applications such as factory automation, logistics warehouses, and outdoor communication backhauls.

Technical Specifications

Wireless Performance

The 6GK5793-8DJ00-0AA0 offers outstanding RF characteristics. Its antenna gain measures 18 dBi relative to an isotropic radiator, significantly boosting signal strength. The impedance is standardized at 50 Ω, ensuring compatibility with most WLAN equipment. Moreover, the voltage standing wave ratio (VSWR) remains below 1.7 maximum, indicating excellent impedance matching and minimal signal reflection. The crosstalk attenuation between the two antenna connectors reaches 30 dB, while the front-to-back ratio is also 30 dB. These parameters guarantee high isolation and directional performance, reducing unwanted multipath effects.

Connectors and Radiation Pattern

This antenna includes two N-type female connectors for versatile cabling options. The dual connectors support applications requiring diversity or MIMO configurations. The radiation pattern is highly focused, with a horizontal and vertical beamwidth of 17 degrees each in the 5 GHz band. Therefore, precise alignment during installation is critical for optimal performance. The antenna's tilting frame allows a maximum downward tilt of 0 degrees, meaning it remains fixed in a horizontal orientation during normal operation.

Mechanical and Environmental Durability

Robust Construction

The 6GK5793-8DJ00-0AA0 features a rugged enclosure made from polycarbonate and aluminum. This material combination provides excellent protection against mechanical impact and UV radiation. The antenna measures 190 mm in width, 190 mm in height, and only 30.5 mm in depth, offering a slim profile for unobtrusive installation. Weighing just 700 g, it is lightweight yet durable enough for permanent outdoor deployment.

Extreme Temperature Range

This antenna operates flawlessly across an exceptionally wide temperature span. It supports ambient temperatures from -45 °C to +70 °C during operation, storage, and transportation. Such resilience makes it suitable for arctic climates, desert environments, and everything in between. Additionally, its IP67 protection rating guarantees complete dust-tightness and resistance to temporary immersion in water. The antenna also withstands wind loads up to 220 km/h and mechanical forces of 104 N, ensuring stable performance even in severe weather conditions.

Mounting Options and Installation

Flexible Mounting Methods

The 6GK5793-8DJ00-0AA0 supports both wall mounting and pole mounting, providing flexibility for various deployment scenarios. However, it does not support ceiling or direct surface mounting. The included installation aid simplifies the calibration process, helping technicians achieve precise alignment for maximum signal strength. For pole mounting, use standard U-bolts or brackets (not included) to secure the antenna firmly.

Alignment Best Practices

Given the antenna's narrow 17-degree beamwidth, accurate alignment is essential. First, use a compass or GPS to determine the line-of-sight direction to the remote site. Next, loosely attach the antenna and connect a spectrum analyzer or signal meter to one of the N-type ports. Then, slowly rotate the antenna horizontally and vertically while monitoring the received signal strength. Finally, tighten all mounting hardware once you achieve the peak reading. Recheck the alignment periodically, especially after strong winds or maintenance activities.

Frequently Asked Questions (FAQ)

1. Can I use this antenna indoors?
Yes, the ANT793-8DJ works perfectly indoors, especially in large facilities like warehouses or aircraft hangars. Its IP67 rating is an added benefit for dusty or humid indoor environments, although it was primarily designed for outdoor use.

2. What is the maximum cable length I can use with this antenna?
The cable length depends on the cable type and the acceptable signal loss. For LMR-400 coaxial cable, keep the run under 10 meters to maintain reasonable performance. For longer distances, consider using an external amplifier or lower-loss cabling.

3. Does this antenna support both 2.4 GHz and 5 GHz?
No, this antenna operates exclusively in the 5 GHz band (5.15 – 5.875 GHz). For dual-band applications, please consider other models in the ANT793 series. The 6GK5793-8DJ00-0AA0 is optimized solely for 5 GHz WLAN and IWLAN networks.

4. How do I clean the antenna's surface?
Use a soft, damp cloth with mild soapy water to remove dust and grime. Avoid abrasive cleaners, solvents, or high-pressure water jets, as these may damage the polycarbonate radome or compromise the IP67 seal.

5. What does the "installation aid for calibration" include?
The installation aid is a simple alignment tool that helps you visually or mechanically set the correct azimuth and elevation angles. It attaches temporarily to the antenna's mounting bracket and provides reference marks for fine-tuning the orientation. Refer to the instruction manual for detailed usage steps.
