Shenglu 4+4+4+8 Hybrid TDD Smart Antenna with Frequency Bands of 700/900/1800/F/A
"4+4+4+8" 700/900/1800/FA hybrid smart antenna realizes FA smart antenna and 700 / 900 / 1800 independent ports in a single radome, and each frequency band is independently electrically tilted. Bands 700, 900 and 1800 are four channel antennas, which are electrically tilted at 0-14 degrees and 2-12 degrees respectively; FA band is an eight-channel smart antenna, which is electrically tilted at 2-12 degrees independently.
The smart antenna works under frequency bands as below:
700: 703 ~ 788MHz
900: 885 ~ 960MHz
1800: 1710 ~ 1830MHz
F: 1885 ~ 1915MHz
A: 2010 ~ 2025MHz
One of our best outdoor antenna's mechanical angle adjustment is within 0-10 degrees, and the diameter suitable for installing the holding pole is within 50-115mm.
The requested RCU is unpluggable and integrated inside the antenna. It supports remote calibration as well as AISG ports available. It can works under environment temperature as low as -40℃.
To improve the waterproof ability, there are four water-leakage holes at the bottom cover in four directions.
The electrical interface between smart antenna equipment and matched RRU equipment adopts multi coaxial cluster cable connector structure.
In the socket connector of multi coaxial cluster cable connector, the c identification port of the 5-joint interface is the calibration channel, and the other 4 channels of the 5-joint interface and the 4 channels of the 4-joint interface are a total of 8 feeding channels. The port of plug and socket shall ensure no loss of electrical performance and mechanical performance after at least 100 times of plugging.
The fixed position of cluster socket and antenna meets the protection grade requirements of IP67. The cluster plug and socket can also meet the protection level requirements of IP67.
When the antenna supports broadcast beamforming, the weight parameters can meet the half power beamwidth of 65°±5° based on the performance requirements of the system, it can meet the requirements of 30°, 90° and 120° horizontal half power beamforming without changing the hardware.
