AFB-450 : Duplex TxRx Antenna Fiber Box

AFB-450 is a duplex remote antennas box that modulates one transmission and one reception antenna signals in one single Neutrik OpticalCon Duo plug. With its rugged housing and 12V on XLR4 power, it is designed for location or live market. The AFB-450 comes with a built-in simple SWR indicator on the TX side. On the RX side a RF peak led indicate if the RF field is too strong. A buit-in 10dB RF attenuator can be switched on at the startup of the device.
Integrated amplifier can output one carrier up to 500mw (27dBm). More carrier can be ouputed with reduced power.
