Ihave had the winegard carryout for 4 years and it has worked without any problems. I know it will work with eastern and western arc satelites and can be used with direct or bell systems with simple switch changes. I live in pa. and use eastern arc because of trees at home sat. 129 on western arc is to close to horizon so I don't have a clear shot at 129 for dish HD service and the same condition could limit use from central pa' to new England depending on elevation and tree height. and it appears that tailgater does not receive eastern arc satelites so depending on your travels this could be a consideration. I also think the carryout uses other recievers that have DVR capability.But double check that I think 722 is the model but am not sure.
The winegard also supports 2 recievers running different stations for a 2nd tv as long as stations are on the same satelite On the other side the tailgater is cheaper and only requires a coax cable not a separate power cord so simpler to set up and can be set up further away from trailer to avoid obstructions without the need to extend the 50 ft. power cord supplied with winegard I am sure picture and ability to receive tv is the same .So decide which serves your needs and get one ,you won't ever regret not having to aim that manual dish .
