RACK SYSTEMS
Most of ETL's sub-systems are designed to fit standard 19" racks. We produce RF distribution equipment for a wide range of applications in the RF chain. On satellite downlinks this is between the LNB and the modem or receiver; and on satellite uplinks it is between a modem and a BUC.Reliability, Resilience and RF performance are designed into all our equipment wherever possible. Scaleability and Adaptability also influence the design process.The main product families are shown below, with further selection of products via functionality and design.
