Conversion Tables
Downlink/l-band Frequency Conversions
A distributor or programmer can provide the latest C-band and Ku-band frequency plans at
purchase time.
If desired, the following formulas have been provided to perform calculations for both C-band and
Ku-band transponders, or if the user is installing for a new satellite.
Calculation for C-Band Transponders
Calculation for Ku-Band Transponders
Formula for L-band frequency:
Example calculation if downlink
frequency = 3,740 MHz:
5,150 MHz 5,150 MHz
-Downlink frequency (MHz) -3,740 MHz
L-band frequency (MHz) 1,410 MHz
Formula for Ku-band frequency:
Example calculation if downlink
frequency = 12,019 MHz:
Downlink frequency (MHz) 12,019 MHz
-10,750 (MHz) -10,750 MHz
L-band frequency (MHz) 1,269 MHz
