Radio & Satellite Frequency Bands

If you hear Ku Band, C Band and L band being discussed and wonder what on earth people are talking about then fear not, it isn't some special code. Radio & Satellite frequency bands are both Historic Radar bands and ITU definitions and they are given letters to represent bands of frequencies.

Satellite Frequency Bands
 
L BAND 1 - 2 GHZ MOBILE SERVICES [ Mostly used for Intermediate (IF) frequencies ]
( 950 - 1750 MHz is the Tx Band and 950 - 1900 MHz is the Rx Band )
 
S BAND 2.5 - 4 GHZ MOBILE SERVICES
( Not used apart from satellite control links & HAM radio. )
 
C BAND 3.7 - 8 GHZ FIXED SERVICES
( 5.7-6.725 GHz is the Tx Band [Linear] and 3.625-4.2 GHz is the Rx Band [circular] also 5.85-6.425 GHz is the Tx Band [cirular] )
 
X BAND 7.25 - 12 GHZ MILITARY
( 7.25 to 7.75 is the Rx Band and 7.9 to 8.4 is the Tx Band all circular )
 
Ku BAND 12 - 18 GHZ FIXED SERVICES
( 13.75  - 14.5 GHz is the linear Tx Band and 10.7 - 12.75 GHz is the linear Rx Band )
 
Ka BAND 18 - 30.4 GHZ FIXED SERVICES
( 27.5 - 31 GHz is the Tx Band [linear] and 19.7 -  20.2 GHz is the Rx Band [circular] also 29.5 - 30 GHz is the Tx Band [circular] )
 
V BAND 37.5 - 50.2 GHZ FIXED SERVICES
( New - not widely used yet - maybe used instead of Ka Band in the future. )
