The Smart Bias Tee combines the performance of a standard Bias Tee (e.g. type 793 304) with the function of an additional modem (AISG standard) in order to provide 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.

782 10253: 12 V version for use near the BTS, in order to feed-in DC voltage and RCU control signals into a feeder cable

782 10254: 12 V version for use near the antenna, in order to control an RCU (only required if no TMA is in use)

782 10255: 24 V version for use near the BTS, in order to feed-in DC voltage and RCU control signals into a feeder cable

782 10256: 24 V version for use near the antenna, in order to control an RCU (only required if no TMA is in use)
