1584-81 RF Combiner The Model 1584-81 is one eight-way, 0.95 - 2.05 GHz, 0 dB gain combiner in a 1RU rack mount chassis with redundant 100-240 ±10% VAC power supplies. The combiner provides excellent RF characteristics. It has eight inputs and one output on the back panel. Two individual 100-240 ±10% VAC input power supplies provide diode ORʼd redundant power to the unit. A surge suppressor on the combiner output protects against high voltage transients. On the front panel, two green LEDʼs indicate the presence of DC voltage from each of the two power supplies. MODEL 1584 COMBINER LNB VOLTAGE
