97W sat can be found on Galaxy 19 or 25 and on some receivers it will show as Intelsat 5 but it's all the same sat. Satellite provider is called GlobeCast and there is some true fta channels and some you have to pay for. In order to get this sat you need at least 30" dish and Linear LNB. It's mostly International channels, here is a link to the channel list for Globecast so you can see what channels are available.

If you are looking for true fta North American channels 123W is your best bet and in order to get that sat you would basically need the same Dish 30" and
Linear LNB. As i mentioned before the bigger the dish the better but 30" will work.
