Modular design
Independent electronics and motors
Mechanical characteristics
TELNET iRET is a completly configurable solution to control the antenna downtilt configuration.
This solution consist of one electronic board and as motors as bands needed to be controlled into the antenna.
Electronics and motors can be added after the antenna installation. Both of them are sold independently from each other.
Main features
Internal RET for TELNET antennas includes 2 control interfaces. Each control interfaces offers one AISG input male connector and one AISG output
female connector. Tilts of all bands can be remotely controlled from any of the control interface.
These two independent interfaces make TELNET antennas ideal for site sharing between two operators without the necessity of any external device.
Bands distribution for each control interface is made through AISG commands .
Female output AISG interfaces are intending for daisy-chain connection with other antennas (in the same or different sectors).
Tilt can be also manually adjusted regardless the presence of RET device.
Tilt indication bar always shows the current adjusted tilt value, regardless manual or remote control
