Two Way Indoor Amplifier Indoor Distribution Amplifier
• High quality hybrid amplification module system at 54/87- 860MHz bandwidth for forward direction and 5-40/65MHz for reverse path.
• For two way amplifier: Plug-in duplex filters are capable of two way Transmission; Reverse bandwidth 5-40/ 5-65 optional
• Two outputs which can plug-in direction coupler to change output value.
• Both the input and output have testing points (-20dB).
• Input, outputs are all equipped with arrestors that reduce mechanical breakdowns from sudden electrical surges
• Trunk line amplifiers allow forward, backward power supply
• Uses high efficiency transformer / switch power
