The ACH-842 is a two channel hybrid diversity combiner, two coax and six fiber antennas towards two BNC outputs. The ACH-862 combiner is available with a switching feature providing eight buttons to switch ON/OFF each antenna. The ACH-862 allows to remote up to three pair of RX antennas over 6 monomode fibers and combine their RF signal with a pair of local RX antennas (connected with coaxial cable to the base). Specially made electro-optical components are used in this equipment. Each antenna can be enabled or disabled with switches on the panel. This device must be used with one or two or three AFB-250. A 12V DC-feed supply, protected from short circuits, can be activated on each inputs individualy (switches inside the ACH). Six indicators « OPTICAL IN » shows if loss on incoming optical signals occured (from AFB-250). Leds will blink if loss is between 3 and 6dB. Beyond 6 dB leds turn off. As with other RF equipments some rules applies in order to get the best from this equipment. FEATURES: bandwidth 470-790 MHz 6 fiber channel 2 coax channels protected 12V DC-feed optical loss indicator ON/OFF of 8 channels
