Combiners (or multi-plexers) allow operators to combine multiple frequencies onto a single run of coax reducing overall costs, wind loads and weight in a streamlined site arrangement.
The Smart Bias-T eliminates the need for the home run cable by integrating DC power and AISG control signals into the coaxial feeder line. If a TMA is not used, two Bias-T’s are typically required – one at the bottom of the tower and one at the top.
