Hybrid antenna combiners can receive both coax antennas for nearby areas (2 active or passive antennas) and fiber antennas for distant areas (connected to AFB-250) combined towards two BNC outputs going to one or more wireless diversity receivers.

The ACH-642 allows to remote up to two pair of RX antennas over 4 monomode fibers and combine their RF signal with a pair of locall RX antennas (connected with coaxial cable to the base). Specially made electro-optical components are used in this equipment.

The ACH-642 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).

Four indicators « OPTICAL IN » shows if loss on the 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 100-850 MHz
• 4 fiber channels
• 2 coaxial channels
• protected 12V DC-feed
• optical loss indicator
