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.

ADH-400 Duplex Station (TX: 2 coax, 2 fibers/ RX: 1 coax, 2 fibers)

ADH-400 is an hybrid duplex station allowing both transmission and reception signals carriage through fiber optics, it also features direct coax input and output. ADH-400 perfectly matches with wireless intercom base stations such as RTS BTR700/800/80.

For transmission section, ADH-400 allows sending RF signal to an OpticalCon Duo fiber output and directly to a nearby coax antenna. For reception section, ADH-400 can combine one fiber and one coax inputs to one output.

ADH-400 works with a duplex remote antenna box AFB-450 (TxRx) through a single OpticalCon Duo connector

Output RF power at the AFB-450 side can be set with potentiometer on the front of the ADH-400 for the two channels (not showed on the obsolete picture).
