Down Converter, 5000 ... 5500 MHz


Working range of the KU LNC 5055 C PRO is the frequency range 5000 to 5500 MHz. The standard IF range is 300 to 800 MHz. Due to four configurable oscillator frequencies the down converter can be used with different receivers. An additional user defineable oscillator frequency solves special requirements on the IF range. For more flexibility the gain of the down converter is setable in two steps. The KU LNC 5055 C PRO comes in a rugged milled aluminium. The down converter is water resistant and ready for outdoor use. For tower mount application a suitable mounting clamp is available.
