Frequency Extender
This ELFE frequency extender can be used with a variety of receivers and operates from 18 to 40 GHz. A dedicated RF input operates from 0.5 to 18 GHz. When the extended range is not selected on the ELFE, the 0.5 to 18 GHz signal is routed through the unit to the accompanying microwave tuner or receiver. A separate RF input accepts 18 to 40 GHz, which is converted to the 2 to 18 GHz range for the accompanying tuner or receiver. The 0.5 to 18 GHz RF pass-through feature along with the down-conversion of 18 to 40 GHz band allows the ELFE to operate with other manufacturers’ equipment of limited frequency coverage while providing full 0.5 to 40 GHz performance.
