The difference between installing a 1GHz RF splitter and a 3GHz RF splitter depends on the service. Although the same footprint and port configurations, the 1GHz splitters are all that is required for cable TV, digital cable TV, or cable internet at and below 960MHz. Satellite requires a start point of 2.4GHz requiring a splitter that is rated from 2.4GHz to 3GHz. When amplifying a 6 and 8 port splitter make sure to match the appropriate amplifier with your installation. A 1GHz drop amplifier should be used for your MOCA and CATV installs and a 3GHz amplifier should be used for your Satellite installs.
