The MB1048R-M can work either as a line amplifier or as a bridger amplifier - the mode can be set by using jumpers. The 4th RF port can be configured as an input bypass port or a 3rd output

• Outdoor aluminium casting case
• Switchable bridger/line extender working mode
• Freely configurable 4th RF port
• Internal return path hybrid module
• 1GHz GaAs or GaN Power-doubler hybrids
• Remote powered switching power supply
• Pilot control option
• Return path noise switch-off option
• Status monitoring option
