Providing you receive a strong digital TV signal and have good quality cable (minimum CT100), with an eight way screened amplifier, you will be able to provide up to eight digital TV signal feeds to the same number of digital boxes and associated TV sets.
Performance will be reduced by long cable runs over 30 feet between the amplifier and any of the connected digital boxes
If you wish to deliver TV to more that eight TV sets through a single aerial or satellite then you should look at communal aerial systems such as MATV or IRS. For more information on communal aerial systems visit the your options page.
