I have a Dishnet 3000 receiver and programming for both 110 and 119. I have just upgraded programming to include 110 channels and have added a second unversal LNB with bracket and receiving good ss on both LNB's (checked with a Birdog meter and individually through the receiver). My question is do I need a specific swith to work with universal LNB's and a 3000 receiver? I have tried a couple different FTA switches but can not get receiver to recognize the 2nd satellite no matter how I switch the cables around. Any thoughts on this? I have seen a SW21 suggested, but wanting to know for sure. Any help would be greatly appreciated.
