RET System without Smart Bias-Ts (Home Run Cable)


The system uses local or remote commands to adjust equipment for the desired antenna performance.
 
System Operation
 
1.       A laptop or network PC running Antenna Line Device Control (ALDC) software sends an AISG command to either the Portable Control Unit (PCU-KIT-4-xx) or Site Control Unit (SCU-xxx-01).

2.       The command is forwarded to the internal or external RET unit via control feed communication cables. 
 
3.       The RET unit performs the command and sends positive feedback to the Control Unit.

Any PC using MicroSoft Windows XP or 7 operating system, and directly connected to a control unit, can run the ALDC software. A network connection may be used instead of a direct local connection for greater control flexibility. An Ethernet cable is used to directly connect a user's personal computer (PC) to the site control unit (SCU-xxx-01). The SCU-xxx-01 site control unit is a compact device providing on-site access to AISG compliant devices via Ethernet or customer network. Antenna Line Device Control (ALDC) software sends and receives commands through the controller to the RET and other AISG compliant devices. The PCU-KIT-4-xx portable control unit provides local access to AISG compliant devices at the antenna site. One or more control feed communication cables transmit data from the portable control unit or site control unit to the RET units and antenna. This style of RET is installed inside the antenna structure and is not visible after installation.  The cassette RET can control a single motor subunit. This style of RET is installed inside the antenna structure and is not visible after installation.  The MDCU can control up to 16 motor subunits. With this style of RET, 100% of the antenna aperature is dedicated to radiating elements providing higher gain for a given antenna size. RET antennas adjust the vertical beamwidth electronically, providing a superior pattern shape than mechanical tilt adjustment.
