This is an image of a Sonora ASPI-20 Power Inserter device mounted on a wall. The device is a satellite signal distribution unit designed to combine LNB (Low-Noise Block) inputs with trunk outputs for television signal distribution systems. The unit features three LNB inputs (marked with red and gold connectors at the top) and four trunk outputs (marked with blue connectors at the bottom), along with indicator lights showing operational status. The device requires 24VDC input power, which is supplied through a dedicated power connector visible at the top of the unit. Three primary cables carry signals from external sources into the top connectors, while additional coaxial cables distribute signals to downstream equipment via the trunk outputs. The device is equipped with green LED indicators to verify proper operational status of the outputs. This type of equipment is typically used in cable television headend facilities or satellite distribution systems to manage and amplify signals across multiple distribution paths.
