There are two types of Ku band LNBFs- circular lnb's which have a low frequency of 11250 mhz,
and linear lnb's, which have three different frequency ranges, universal -

9750mhz-10600mhz (European model), universal - 9750mhz- 10750 MHz, ( U.S. model’s use both and are wide band LNBFs), and standard - 10750mhz.

Here is a list of satellites and the correct lnb's to use with them:

61.5W Echo 3 - use standard circular lnb - 11250 MHz

63W Estrela - use linear lnb, either universal or standard linear- 10750 MHz

71.8W Nahuel 1- linear lnb, either universal or standard linear- 10750 MHz

77W Echo 4 - circular standard lnb - 11250 MHz

79W Amc 5 - linear lnb, either universal or standard - 10750 MHz

82W Nimiq 2 - circular standard lnb= 11250 MHz

87W Amc 3 - --- linear lnb, either universal or standard - 10750 MHz

91W Galaxy 11- linear lnb, either universal or standard- 10750 MHz

91W Nimiq1&3- circular lnb standard= 11250 MHz

93W Intelsat 6- linear lnb, either universal or standard-10750 MHz

95W Galaxy 3c- linear lnb, either universal or standard - 10750 MHz

97W Intelsat5- linear lnb, either universal or standard - 10750 MHz

101W Amc 4 - linear lnb, either universal or standard- 10750 MHz

103W Amc 1- linear lnb, either universal or standard- 10750 MHz

105W Amc 15- linear lnb, either universal or standard- 10750 MHz

107.3W Anik - linear lnb, either universal or standard- 10750 MHz

110W Echo 8 & 10,X - circular lnb standard - 11250 MHz

111W Anik f2 - linear lnb, either universal or standard - 10750 MHz

121W Echo 9 - linear lnb, either universal or standard - 10750 MHz

123W Galaxy 10r - linear lnb, either universal or standard - 10750 MHz

127W Galaxy 13 - linear lnb, either universal or standard - 10750 MHz

129W Echo 5 - circular lnb standard - 11250 MHz
