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).
