Choosing the right one:

• DBS / DSS / Circular LNB's are those used mainly for Echostar and Nimiq satellites (61.5, 82, 91, 110, 119, 148). They have a LO frequency of 11.250 GHz
• FTA / FSS / LinearLNB's are used for 121, AMC4, Galaxy25 (T5), Galaxy10R, Galaxy3, etc. They have a LO frequency of 10.750 GHz. Note: these satellites require a 30" or larger dish
• 118 / 118.7 LNB's are used mainly for 118.8/119 Anik F3 LNBs or 118.7. They have a LO frequency of 10.750 GHz. Note: these LNB's are circular polarization and can also be used for all DBS/DSS type satellites including 61.5, 82, 91, 110, 119, 148, etc
• Universal LNB's are a dual-band LNB often used for satellites in Europe. In North America, the only satellite that requires a universal LNB is Intelsat 9 (PAS9) at 58°W. Universals are a kind of linear LNB and can be used for any linear satellite. They have LO and HI frequencies of 9.750 and 10.600 GHz
• Invacom Quad PolarLNB's are a special type used for mainly for motorized dishes. They are an all-in-one LNB, giving you both circular (DSS) and linear (FTA) polarizations at the same time
