WHAT IS A MULTI-SWITCH? If you want to use more than two receivers on a DSS (DirectTV),TIVO or DISH Network system, you must use a dish with a dual lnb and a multi-switch. This switch enables you to connect 1 to 4 receivers to one dual lnb dish. This switch should be mounted inside and has two grounding lugs to replace your grounding block. There is also a terrestrial input that allows you to connect an off-air antenna or analog cable signal for local channels (to separate the signals you will need a diplexer at each receiver you wish to use the off-air or cable signal).
NOTE:Will Not Work With DISH 500 SYSTEMS!!
