The Smart Bias Tee combines the performance of a standard Bias Tee (e.g. type 78210577) with the function of an additional modem (AISG standard) in order to provide either DC voltage as well as remote control signals via an RF feeder cable to a TMA or RCU.

The Smart Bias Tee provides low RF signal insertion loss from port 1 to port 2 and vice versa.The measures taken to protect against static discharge and lightning ensure a high level of reliability and operational safety.
