Overview
4O3A A50 Antenna/Load Switches
4O3A A50 Antenna/Load Switches serve as 50-ohm loads for open ports on the HFC4500 combiner or other multiplexer, preventing tuning degradation. Applying 12V power connects the input to the combiner's output, linking it to the corresponding combiner or filter. A typical setup switches a filter or a combiner to a monoband antenna. When the A50 is not powered, the switch defaults to a 50-ohm termination for the input and the antenna output is open.
NOTE: The A50 is NOT an A/B switch. The manufacturer's label of "A/B Switch" is a product grouping, NOT an indication of the function of this product. The LOAD resistor is internal, so one of three connectors is unnecessary, which leaves an open hole in the chassis, a "normal feature" of the A50.
