I was wanting to get a second satellite dish and set it up at our Boat Marina. This would allow me to take my Vip 211 receiver from home and watch Standard Definition (will use regular non HD TV) TV out there. My question is what dish antenna do I need to get? Do I need a special LNB? since this is a HD receiver (again watching standard definition). Craigs list has several dishes listed cheap but I am unsure If they would work. Any help would be appreciated.
