The problem with the portable automatic antennas is with two TV's and two receivers, they both must be on the same satellite. The Receiver on #1 output controls the satellite. You can watch two different channels, but they must be on the same satellite.
What we have seen is people use two portable antennas to get multiple satellite reception.
Dish has a monthly plan that has no contract.
Here is the Winegard antenna list for the different receivers. None of the automatic portable antennas will work with a Hopper receiver.
