im totally new at this and honestly have no knowledge about how the whole fta systems work..this guy online was going to install a system for me for like 350...the thing is i see that u can buy the receiver and all the equipement for alot cheaper..i already have a dish on the roof because the previous owners of the house had directv...so i was hoping i could use that one...i really dont know where to start though on figuring out how to do this..if anyone could help i would be very thankful
