Teletilt Bottom Smart Bias Tee

PART #  464720
Minimum 1 EACH


The item has been discontinued by the manufacturer.

The AISG Smart Bias Tee is designed to eliminate the long AISG data cable run from the base to the top of a cell site tower by electronically injecting (piggy-backing) power and control signals onto an existing RF coaxial cable run. ; There are multiple options used to divide the AISG signal from the RF cable onto control cables leading to the antenna line devices at the top of the site. One option is to install a Smart Bias Tee at the top of the tower, below the Teletilt RET devices, with another Smart Bias Tee installed at the base of the tower. Each Smart Bias Tee is equipped with a grounding stud that requires a grounding kit (ordered separately) to provide additional lightning protection. These Smart Bias Tees are RoHS and AISG compliant.
