RE: Satelite
If you decide that you want a satellite, there are a number of options. You can go with a dome style or a parabolic dish style. As you should not have anyone in the FW while moving, there is likely no reason to purchase a dome style dish. A parabolic dish will give you much better performance.
In a parabolic dish, you have a variety of options. You can get a tripod mount, or a roof mount. The advantage to a tripod mount is that if you are parked under a tree, you can move the dish to where you can get a signal. The disadvantage is the time to setup, as well as dealing with the weather during setup. In a roof mount, you can get a manual or automatic dish. The manual is just that, you crank up the dish and calculate where the satellite is and locate the satellite manually. The automatic dishes are the most expensive, but the easiest. Simply park, push a button, and in a few minutes you have TV.
As a side note, you can get multiple LNB's on a parabolic dish so you can lock onto 2 or 3 satellites simultaneously. With that setup, you never have to repoint the dish to get programming on a different satellite.
Each of these setups would require service with DirecTV, Dish Network, or Bell ExpressVU. As another reply stated, if you currently have service with a company, you can use an extra reciever and it would be part of your home service.
