Downlink/L-Band Frequency

Conversion Tables

A distributor or programmer can provide the latest L-band frequency plans at purchase time. Use the formulas in Table 5-1and Table 5-2to perform calculations for both C-band and Ku-band transponders, or for installing a new satellite.

Table 5-1: Calculation for C-Band Transponders (Using 3,740 MHz Downlink Frequency)

Formula for converting a C-band Frequency to an L-band Frequency	Example calculation if
	downlink frequency is
	3,740 MHz
5,150 MHz <minus> Frequency Downlink (DL) <equals> Frequency (L-band)	5,150	MHz
	-3,740	MHz
	1,410 MHz

Table 5-2: Calculation for Ku-Band Transponders (Using 12,019 MHz Downlink Frequency)

Formula for converting a Ku-band Frequency to an L-band Frequency	Example calculation if
	downlink frequency is
	12,019 MHz
Frequency Downlink (DL) <minus> 10,750 MHz <equals> Frequency (L-band)	12,019	MHz
	-10,750	MHz
	1,269 MHz
